Hi,
I've noticed an audio output distortion of some frequencies when listening to music, in the sound coming out of the 2.5mm jack.
When the speakers on the device is used, there is no problem.
When I plug the headphone, there is sound output, I hear the music, but some frequencies are lowered so much that I can't hear the singers voice. When I unplug, the speakers work fine and I can hear the singer again.
In additon that, most of the background instruments can be heard as well as the backvocals, if they are female.
It's like the sound is being processed (like an equalizer) when I plug the headphone, some frequencies are lowered, given some echo, reverb etc.
I don't understand how this is possible. I am thinking of a hardware contact problem, but it's hard to believe if this is a hw problem.
I've tried two firmwares (2.16.x, 2.25.11.1) and made hard reset also. No result.
Any ideas?
Note: I can try to actually record the sound tonight if anyone wants to hear.
Best regards,
Fast
maybe try a different headset first?....could be a short in the cable, because what you are describing is a phasing issue with the headset speakers......
Thanks for the response Kiru,
Just tried a different headset plugging it into my HAMA 2.5 --> 3.5 adapter. same result.
I will try the original headphone came with the Wizard. If the source of the problem is the HAMA adaptor, this should resolve it. (i hope it is)
Could you please elaborate on the "phasing issue" ?

Hmm....how can I explain.....Let's start with the speaker itself. A speaker has two terminals on it, one postive and one negative. What we want is to have the positve from the source (ie. Amplifier) to the positive terminal of the speaker, and the same for the negative. Since there is a pair of speakers, we want them to be hooked-up correctly. If hook-up correctly then the speakers are in phase with each other, and this is called constructive interference, hence in phase. When ONLY ONE of the speakers is hooked-up backwards, we call this destructive interference, hence being out of phase. Being out of phase causes frequencies to cancel or sound muffled. Hope you kind of get what I mean, but I highly doubt that this is the problem with headphones because heaphones nowadays rarely get manufactured with this problem. This is just the electrical part of phasing. Also, you can have one speaker, and it could sound out of phase because of the distance it is firing from walls or the shape of the room due to the reflections of sound, this is called acustical phasing.
A short in the cable, meaning the positve and negative wire are somewhat touching, can cause a similar effect, and I suspect that this is problem for you. As you now state that you are using an 2.5 to 3.5 adaptor, I would agree with you that most likey you have a faulty adaptor.
Hope this helps! and keep me posted!
Hi again,
Thanks again for the explanation Kiru, I know a bit of electronics so I got the problem.
However, I'm now home and tried to original headset, no result. The same problem is existing.
This makes me believe that I've broken something inside the Wizard which shortcircuits something. I'm very dissapointed.
Maybe the only way is now to buy a stereo bluetooth headset...
Thanks for your help
Any reason that you can't return to orange for repair/replacement?
PROBLEM SOLVED
I got this unit from priceminister second hand. It's origin is not France, I don't have a purchase receipt neither.
By the way, I solved the problem. I disassambled the unit using the info given in one of the posts in the forum. I played a little with the contacts, there was oxidation in the outer solders, i cleared them up etc, it 's working at the moment.
I'll post some pictures afterwards.
and I hope i will be able to reassamble it, I already have a piece of thing which I don't know where to put
I got the same problem. Was working fine for 2 months then all of a sudden the headphone plug is all messed up. Volume is all distorted I can sometimes hear a song but quality is no where near the original. Usually everything sounds echoed. I think something is wrong with the plug
I've had the same problem. The headphone jack on the Wizard is crap. If you have your Wizard in your pocket with an adapter, as you move, the adapter pries back and forth on the jack. This breaks the cheap jack.
If you want to listen to your Wizard as an music player, you should invest in a nice set of bluetooth headphones and only plug the jack in when the wizard won't be moved around a lot, like a home or car stereo.
I recommend Nextlink Spider headphones. They double as a headset and you can navigate through your library with the button on them.
MUSIC Speed
I got the same problem here. The SE stereo btooth headset isnt yet in our place.
Anyway, i experienced this one with ROM2.16 Imate. The sound speed or music speed seems to being played faster than normal. But when i tried to plug the 2.3-3.5 adopter and quickly pull it out, the sound is played in normal speed then. strange.....
are you all sure that the wizard has a stereo output ? I thought it was mono.
Anyway you can get earpieces and headphones with a 2.5mm jack so you don't need a 2.5-3.5mm adapter.
Maybe the contacts on your jack are not connecting properly with the internal contacts of your adaptor
I have found some strange behaviour that i'm hoping someone else can test out on their Galaxy S.
I have found that some headphones seem to work fine with the phone for music playing but others result in the sound being distorted with the vocals being very faint as if the left and right channel are cancelling each other out (with vocals generally being on left and right channel).
The packaged Samsung headphones appear to work properly although the quality seems average. I tried my iPhone headphones but these resulted in the strange sound distortion described above. I also tried a pair of cheap Sennheiser which were a free give away with a purchase from Richer Sounds and they worked well. Another pair of no-name cheap headphones exhibited the same distortion problems as the iPhone headphones.
Oddly, the FM radio sounded ok with all the headphones, it's just the music player that has the problem. I have also tried a couple of other music apps including the doubletwist player to rule out the software.
I'm considering taking it back to the shop to swap for a replacement. I'd be grateful if anyone could try out some headphones (particularly iPhone ones) on their Galaxy S and report their results to see if this is just a quirk with my phone or the Galaxy S in general.
Many Thanks
I just need some clarification because I know that a headset, and not headphones, is delivered with the Iphone. If it was a headset then I might suspect that different Iphones use different polarity as opposed to Samsung. Try out the Samsung headset on the Iphone.
EDIT:
Obviously not the problem. I must have skipped over the radio experience.
I can't post a link to it, but I remembered that GSMArena did a thorough review of the SGS. If you find your way to it, go to page 6 and see the sound chart at the bottom. SGS is superior in sound to iPhone. Perhaps the iPhone headset/headphones and the cheap ones are not sufficient for the SGS? I'm guessing
I had a similar experience when I tried to use the Samsung Spica headset on my HTC Hero. It seems that it might be a difference in polarity as suggested above.
Does all the headsets that give distorted sounds have a microphone on them? (E.g. not headphones)
the iPhone's headphones have extremely high distortion regardless of the media using to play them. The SGS is probably just overpowering them because they are very loud headphones as well/easily powered.
No it's nothing to do with them being overpowered.
I have an expensive pair of etymotic in ear headphones that are exhibiting the very same problem. Strangely I found a fix. They have a microphone on them and pressing in the answer button on them seems to fix the problem. I have taped the button down now and everything works perfectly. The second that button is released though, everything goes back to being faint, muffled and distorted.
Odd!
PS. This isn't just with the music player. I noticed it first watching a video.
It sounds like Samsung has their own way of producing the 3.5mm port with regards to the microphone support.
The Samsung headset distorts music on my HTC Hero.
The HTC headset distorts music on my gfs Galaxy Spica
To be clear, are you saying the problem only affects headsets with microphones? I have etymotic er4p headphones and it would be a deal breaker if they didn't work right with this phone.
If its only showing up in the media player, check that you havent enabled the 5.1 button in the the top right of the player. This can really screw with the sound and entire frequency ranges can be lost. I'm guessing this is whats happening.
The default headphones work fine for me if a little tinny, but with my Senheissers, the results are very pleasing. Apart from a slight gap between tracks that should seemlessly play through, I prefer using it to my iPod Touch. Being able to change tracks and volume without unlocking is a nice feature.
I threw my iPod headphones out years ago, they're the most ridiculous design ever, with the cable tapping the inside sleeve all the time when you walk or run.

It sounds like that the problem is with headsets with microphones, yes. Not sure if it happens with all 3rd party headsets w/ mic though.
Considering you have etymotic, and ClownShoes a few posts up have problems with this brand, I guess you're out of luck unless you wanna tape the answering button like he did.
The er4p is just headphones, so it sounds like i'm in luck.
Got my GS a few days ago and im having exactly the same problem with the Etymotic hf2 Headset with mic. So yeah it looks like it the mic that causes the problems.

It's a little bit crude, but taping the button down does work.
I have the same issue with with Monster Studios even with the cable without the integrated mic. Would be great to have some sort of fix.
Headphone issues
Just thought I would post what I knew about the issue, both me and my dad purchased the same pair of headphones to use on mp3 players (the headphones are ultimate ears metro fi 220 vi's if I remember correctly, these have an in-line microphone as well as a single button for answering calls and to control music playback). Whilst I experienced no distortion when using them on my iPod Classic, my Dad's Creative player would produce the issues described above - he found that either taping the button down or slightly pulling the headphones out would solve the issue however it ended up annoying him so much that he went back to using another set of headphones.
I don't know what causes the issue but I just thought I would let people know
i have some sennsihaur sport headphones which work fine no problems. i also a monster fm transmitter in the car.. again no problesm.. just make sure the volume is not on max but 1 setting below max.
Hmmmm, a few problems here. Obviously the standard Samsung headphones are fine, no humming, no background noise. However if I connect the following:
1. Standard Apple iPhone (with mic) loads of background noise, humming etc
2. Shure (no mic) loads of background noise, humming etc
3. B&O (no mic) loads of background noise, humming etc
4. Shure (with mic adaptor) loads of background noise, humming etc greatly reduced by pressing the mute key.
Using the Shure adaptor with the others resulting in the same as 4.
Needless to say I'm not happy!
That's too bad. Not being able to use my Shure with the phone renders it useless for music and that IS important.
In the SERVICE MODE *#*#197328640#*#* there is an audio menu
there you can change the headset settings too like NR noise reducion.
i did not test and changed the settings but when i had the samsung omnia2 last year
i had some problems with my headset and fix it in in the sevice menu.
when you gonne do some tests write down the orginal settings before you try.
hope this will help some of you..... and post the results
im sure its the jack, cos the galaxy s has a 4pole trrs at left/right/mic/ground
iphone compatible headset have a 4pole trrs at left/right/ground/mic
thats why pressing the mic button clears up the sound as it closes the circuit
so it a matter of finding an adaptor that switches the mic and ground terminals
I have a tf10vi and im trying to diy one
will post the results
Just saw the post and thought I would check mine again, not that I noticed anything....anyway tried few songs and different types and all are sounding amazing, I use Sure 530 so music needs to be no lower than 256 to get the best out of the phones, most of my music tracks are 320bit.
Guys,
Another day, another observation. When you plug in the headphones, do you guys hear a hissing/static/white noise for a couple of seconds initially. I am able to reproduce this every time I plug in my headphones (tried three different sets). I am not too bothered by it because the noise dies after 2-3 seconds. I also witness the same behavior when I pause a song.
I guess I am raising the topic here because am not sure if this is common across all WP7 devices (thereby making this a WP7 issue), if it is only my phone, or if it is common across all Venue Pros.
Thanks for any input.

I get the same noise, but mine is constant. Whenever a sound plays, the white noise/hissing in the background comes up and continues for 5-10 seconds after the sound is played and then goes out. Then when another sound happens, it does it again.
It almost makes using headphones unbearable.
I've tried multiple sets of headphones too, it does it on them all.
I think it may have something to do with the curved top of the phone and the fact that the plug doesn't go all the way into the device.
Anybody else have a similar experience?

I don't think it's that - if the curved surface was the culprit, the sound wouldn't vanish after a few seconds. It almost seems like a software issue.
Thanks for confirming the behavior!
I only hear the hissing sound for a few seconds after plugging it in to the jack...
Hearing a hissing on most smartphones is pretty common, in my experience. The better quality earphones you use the more you will notice it. The Nexus One did, the Venue Pro does, my N95 did a bit.
People I've called with the built in headphones/mic say the noise levels are so extreme they are unusable. Hopefully the free Bluetooth headset we're all getting will fix that issue...
Hello!
This is normal when companies use cheap DACs and amps for sound replication. The DAC turns on when you play sounds, and turns off when there's a period of no sound. If it's a cheap system, there's a noticeable base sound/noise that is added to your signal.
When you have music playing, that, of course, is drowned out by the music. Thus, you won't hear it unless you have really soft music, say, a few bars rest in your classical album or something.
The problem also is more noticeable with low impedance earphones (IEMs, for example).
A possible, easy way to fix this is to use an inline resistor/impedance cable on your headphones, since typically this noise does not vary with volume (in my experience). Then, you bump up the volume on your device... if it's powerful enough to do it. Otherwise, you'll have to inline resistor, a clean-sounding portable amplifier (powered by additional), and then your headphones. It gets pretty bulky...
Alternatively! Separate your music player and your phone. Unfortunately, the DVP has such a nice Zune interface. And still, with cheap music players you can hear the hiss if you're careful. I can hear this on iPods with my earphones still...
Sorry to hear about this! I was hoping that the sound quality would be decent. I might try to get an HD7 instead now...
Cheers!

Just to let you know, the HD7 does not have the hissing/static that the DVP does. I've tried the HD7, Samsung Focus and DVP and HD7 had the best sound quality in my opinion. The Focus sounds muffled compared to both HD7 and DVP.
I've got the same hissing noise on mine, but I think it's an issue with a crappy DAC as it's only there when there is sound. I was hoping to replace my Zune HD but there's no way that's gonna happen with this noise - it's AWFUL!
I'm really thinking about moving to a Samsung Focus. I loved this phone when I first got it, but over time I just uncover more and more I don't like.

Very true. Almost every phone I've used has this. It's more noticeable on some phones than others but it's nothing unique to the DVP.
Bringing this back to the top, I've observed something on my new model, though I could have sworn the one I sent back for a refund did not have this problem...and it only occurs with earbuds, and not ear phones (I have a big pair of medium to high quality full-size Creative earphones, the buzzing is not audible at all with them.
Since this phone seems reasonably crash-free, I'm reluctant to press Dell for a replacement, especially if, viola, all the DVPs have this problem. Mine seems particularly loud, but that may be a combination of the Zune Premium earbuds I'm using and other factors. As others said, it vanishes briefly if you pause a song (like the sound output is switching off to save electricity or whatever) but resumes immediately. I might be better off just going through various earphones and finding a brand that's of at least the quality of my current earbuds but minimizes the effect.
EDIT: Additionally, lowering the volume simply makes it much more noticeable.
Hi, does someone have the same experience when connecting a headset to the TF?
I have to adjust the plug very precisely, since it can be pushed further into the device. Otherwise I loose left or right channel.
Is it less than 3.5mm? Or is some of where the wire means the plug (usually chunk of plastic) cut off?
no, it's an almost brand new inear headset which came with my Xperia Neo phone. I assumed the problem being caused by a sloppy assembled connector. If it works fine for everybody else, then it must be an individual defect with my TF
yeah i have a cheap pair of sony headphones and they work fine. just the volume isnt the best....but i know that is a tf issue not a headphone issue.
Yes, volume is a horror. I expected better. Haven't tried volume+ yet, works fine on my android phone.
To be honest, I wouldn't necessarily attribute the volume to the TF101. I have a decent pair of headphones and the volume works fine. Also, I've never noticed anything about the plug being finnicky.
I wasn't complaining about the sound but about the max. volume level. It seems to be a little low on my device. It may comply to some EU laws - I assume.
Anyway since nobody else has issues with the headset connector, I have to check with my dealer.
i'm having a similar issue but not exactly the same.
i used to have a problem with the 3.5" jack only when i plugged it to my surround system- logitech x530. i supposed it was because the signal is being amplified. so when i touched the connection or rotated it at his place it made a lot of loud static noise. i've tried changing cables but the same.
so i've got the lab to replace my transformer's mother board or so, and it is still happening. in fact i've noticed a new problem, this time with just a simple earphones.
when i push the plug a little bit harder into the jack, the sound becomes a bit louder.
wierd stuff... and of course in general the max volume kind of sucks.
I've noticed a similar issue with several of my plug-in phones.... Some work great whilst others either have no sound or mono only.
To me it appears the connector on the TF is simply too picky.
I have a pair of meelectronic A151 armature iems as well as Vsonic GR07, and while i like my music loud, clear, and with a lot of instrument seperation, maxing volume is definitely not needed.
Quick fix would be to flash a Rom/kernel compatible with Supercurio's Voodoo control and install Voodoo. It will be louder and sound clearer.
http://forum.xda-developers.com/showthread.php?p=14914293
Long term fix would be to buy a better pair of iems/headphones. Armatures like the A151s I mentioned above for clarity, a good dynamic driver like Meelec CC51, Sunrise X-cape, if you're a basshead, or VSonic's GR07 if you want a nice combination of both.
I'm quite a bit of an audiophile and while it surely isn't THE best DAC out there, the Wolfson WM8903 is very very good.
Also, depending on what phones you're using, you may just need an external amp, especially if their impedance is rather high.
Edit: I realize I went more into the sound aspect, as it was also being discussed above, but all my iems fit my TF snug just like all my other devices.

If anything mine is too tight a fit, but works perfectly with any headset I've tried.
Hi all,
So I recently bought a new LG G3 - after having screen problems with the Oppo Find 7 - had the Oppo fully refunded, so was on the hunt for a new phone.
Bought the LG G3 instead - great phone (apart from the stupid button placement)...but there's a fundamental flaw with it - just sharing this here, to hear if anyone else has been testing it the way I have done in the video:
(Essentially the audio has a buzzing noise to it, when using the phone - this happens when you amplify the source)
I don't find it acceptable for a 2014 flagship phone to be like this.
I'm on the fence now to root it and/or flash another ROM OR just return it for a full refund - anyone else have any experience with different ROMs (ie 5.0 ROMs)?
EDIT:
I'm returning the phone: http://forum.xda-developers.com/showpost.php?p=57514537&postcount=12

That "beep beep" sound when connecting your audio jack appears to be unique to your device as I haven't seen any other G3 do that before.
Also, I stated in another thread about this issue, It only happens while the cpu is under load AND there is no audio.
Once the cpu load drops to idle the issue is gone.
Once there is audio playing the issue is gone too.
It's annoying while no audio is playing, But it's not gonna degrade your audio experience in any way what so ever when there is sound coming out of your phone.

Well that's odd, I've gotten others saying the beep beep is normal, but the buzzing isn't lol.
Out of interest, do you have the same issue?
And it's also a matter of principle, rather than it also being a fundamental flaw in the design. No flagship phone should have such an issue.
Whilst music is playing it's not noticeable at the levels I play it at, but at low volumes, and whilst using the phone at the same time, I can hear the problem. I'll retest tomorrow to make sure.
Not because I'm looking it for it, but because something doesn't sound 'right'in my music.
If it's CPU causing it, then is it linked somewhat to the kernel (ramp up and down of the CPU) or is it due to the placement or 'communication' it has to do within the phone (hardware problem)?
Mine does the Beep beep thing when i plug in my phone to the sound system at my work. It's done it on every ROM i have tried. The hissing, i haven't heard for a while though.
To be honest though, it is completely unacceptable it's not been sorted though yet.

Hi !
I think the audio system is the only problem with this phone.
When hearphones are plugged and there's no sound, you can hear a weird sound (especially when you touch the screen).
I also have a problem when I listen to music, sometimes the music has a little lag, a little buzzing for less than a second, as if the phone didn't have the time to load the music. It sounds like an old used CD. It happens once every ten minutes approximately. I don't know if it comes from the fact that I listen to music from my SD card, which isn't a very good card (64Gb, 20$ on amazon). I should test it from internal storage to check that...
Anyway, I'm using ChupaChups ROM and the problem you're talking about is also present. But Chupa Chups is a stock-like ROM, so this isn't a surprise.
I'm planning on installing CyanogenMod to see the difference.
I'll report back here after that

What hidden menu ? Dev options ?
ChupaChups ROM includes a mod which allows the processor to have an higher temperature (I think the original limit is 65°, the mod is set to 75°). The mod is supposed to erase this kind of issue.

Legend - seems hardware related (as initially thought)
Unless CM use the same stock kernel - highly doubt that though!
OK guys - went into O2 store in the UK - they had a G3 on display.
(It was plugged in) - I could hear a LOT of static noise on my earphones with the amp connected.
Then I unplugged it from the mains - the static went away.
I then did the same tests as before and boom - same issue.
It's 100% not my device only and is present in the international G3 version.
My LG G3 is being returned tomorrow. It's unacceptable.

OK so I did tests -
Without the micro USB cord connected:
Audio playing - 0% volume (thus you can't hear anything) - static noise, no HDD-esk noise
Audio playing - 1st notch (you can hear music faintly) - static noise, no HDD-esk noise
Audio not playing - HDD-esk noise
WITH the micro USB cord connected - charging:
Audio not playing - Louder static noise, minimal HDD-esk noise
Audio playing - 0% volume (thus you can't hear anything) - louder static noise, no HDD-esk noise
Audio playing - 1st notch (you can hear music faintly) - louder static noise, no HDD-esk noise
Hope this helps everyone looking at this thread
So, I have a set of Sennheiser HD 598, a pair of Monster DNA headphones and Sennheiser CX275S in-ear earphones (for Android smartphones).
When I connect the HD 598 and the Monster DNA to the phone directly. I get no noise.
But when I connect the CX275S, I get the noise.
Could it be something to do with the impedance/resistance of the headphones and/or cable that is being used?
However I am not using an amp. Do you get the noise without the amp? Have you tried a variety of headsets??

Yes it can be the impedance - however this doesn't apply when I connect the amp -as it is picking up more than the source usually shows.
In other words - you CX earphones could be more sensitive (which I find surprising vs the HD 598) - but if you were to put an amp - I think all of them would show.
I've tested with a bunch of earphones and my headphones - all of which showed the same problem with the amp.
I know for sure now it's to do with the phone - now if some people would notice it or not with their given setup is another thing.
ie. their setup might not reveal the flaw (ie if I had never put the amp - I wouldn't have heard the problem).
Also - I've noticed a audible "click" / "lag" when music was changing. making me say: "Yup 100% this phone is being sent back"
Can't believe I'm back to my SGS3. over 3yrs old - no problems and trumps these flagship phones in terms of audio quality.
Just to add my part, the "beep beep" is normal when connecting headphones. I usually get a very quiet buzzing noise when I have the phone connected to a power source and have headphones in. I'll report back in a week, getting a warranty replacement so may be different
EDIT: Using a pair of Audio Technica CKS-77X in ear headphones

excellent thanks for letting me know - why are you getting a replacement? (this issue?)
I've already packaged mine ready for an amazon return.
I decided to pull out all the earphones and speakers that I have. And here are the results.
1. LG earphones that came with the phone - no noise
2. Old Samsung Galaxy S2 earphones - no noise
3. Old iRiver earphones - no noise
4. Sennheiser HD 239 headphones - no noise
5. Bose Soundlink speakers in aux mode using a cable - at the highest 2 levels of volume I can hear the noise.
So it may be an amplification issue.
I am not sure that LG would accept the product back here in Australia if I tried to return it as there is no noise with the supplied earphones and any problems with amps would probably be out of their warranty terms.

Cracks on the top IR Blaster (the one used for Quick Remote not for the camera) and your bottom microphone. Its a know defect with the G3 and they'll replace the phone for free

Not an amp issue - I think I showed that by comparing multiple devices.
It's the fact the source doesn't like to be amplified - and when done so, shows these problems quite easily.
The source (LG G3 jack) doesn't seem to be isolated/shielded well - that's the issue. Therefore normally nothing happens, crank the source up a little and it fails miserably.
It's 100% down to LG here - I won't say it again, but I've returned the LG G3 now. I'm done with their crap implementation. How on earth they would have missed it is beyond me.
Reviewers also need to wake up when they do audio tests. Useless.
