So I am getting this buzzing/hissing sound from my ear speakers. It is only noticeable when I hold it very close to my ears in a quiet room. But then it is quite easy to hear. The sound changes all the time. The frequency is different and there is a click sound every second or so.
It doesn't matter if the screen is on or if the phone is in stand-by. A restart didn't help.
I have never noticed this before so it might be my manual update to stock 4.3 that caused the problem. But it might have been there before the update.
It is not really bad because you only notice it when you call someone but it might eat up my battery.
That's normal and not even exclusive to your (our) phone
It's caused by electrical noise

Hi guys,
I've found a very interesting sound effect on my O2 XDA Mini (=Magician). I've been having the phone for a few days only, but right from the very first calls I noticed that the speaker creates a very high frequency continuous beep-sound, not loud of course, but crazy high, something like the well-known side effect of the old CRT TVs. At first I thought it is produced during a conversation. Then today, I held my phone to my ears without any calls, and guess what: the beep is there. :shock: It's produced always!
I started to look around, and had a hunch that the LCD backlight can be the problem. I played a little with the backlight setting and found that I was right, the sound is poduced only when the light is set to low. It's loudest at the first notch of the light slider, and gets more and more quiet as you set the backlight higher.
Now I wonder if it's a special problem with my phone (like some bad quality filtering somewhere in the power electronics of the backlight system) or if it is the same with your devices.
Please try it and post your comments. Listen closely! And try both ears (not kidding), the sound is very quiet and very high in frequency, so your ears may not be up to the task to pick it.
Have to be honest I can't get a quite second at the moment but I'm pretty sure I've noticed this noise before as well. Another noise which can be irritating is the GSM radio module and it's intermitting buzzing (a quiet version of what you hear when unshielded speakers pick up your signal).
So basically I'm not sure but I think it's a generic issue with the backlight
Hi,
I found that too....
it's quite irritating as it looks like an old TV turned on.
I hope that won't be a problem to our ear in the future
I have a bit of curios problem with my TD2. During a phone call i get a sound distortion / vibration from the earpiece. It makes no difference if i change the volume level. Playing music or using the speaker phone does not cause the problem. So i'm not sure if it's a software or hardware problem? Has anyone else found this problem? or have any clues for me.
Thanks in advance

It isn't related to the "vibrate on connect" feature is it?
No i have that disabled. It sounds like when a music speaker has a damaged cone and vibrates / distorts or there is too much bass?
The distortion in my earpice goes away at 80% volume. Is very annoying. It distortes on bass (low frequency) very much on 100% volume. The D2 speaker is very crappy. I wonder if there is a solution to this (software bass reduction of the incoming calls).
I agree the earpiece is utterly crap, the distortion goes at 50% on my TD2! Have spent sometime looking if there is anysoftware solution but to no avail!! I'm debating weather to return it under waranty as a faulty phone and see where i get.
any solves on this issue?
Mine too have the same problem, but i was told by others owners that this situation is not normal.
They say it´s a faulty device.
Result!! My touch screen went faulty so had to send the phone back in for warranty repair. I mentioned that the ear piece may also be faulty and requested them to take a look. Phone returned with new screen, new housing & i must assume a new ear piece. All distortion has disappeared even at 100% volume!!!
Maybe it's not the thread to mention it in (apologies to all those with problems) but when it works properly the TD2 has the best sounding earpiece of any phone I've had, including two other HTC ones. It actually has bass!
The distortion described sounds like the moving part is partially rubbing against the fixed part. In a proper speaker this can be caused by dirt or dust trapped between magnet and coil, or distortion of the coil through overload or temperature changes. I would send the phone for service 'cos it sadly won't get better of its own accord.
Hi all.
I just received my a500 a few days ago.
I have Thor 14.2 on it now, and have been enjoying it. However I noticed the speakers have started making a ticking noise. Kind of like what you would expect from a hard drive, or something electrical turning on and off quickly.
At first, i thought maybe it's a hardware issue. Whats interesting though, is that the sound is only present when there is nothing else using the speakers. As soon as I turn on some music (even the very lowest volume) it no longer ticks. Pause the music, and the ticking is back.
This makes me think the problem is software, considering there shouldn't be any change between the tablet not playing any sound via speakers, and music via speakers, in so far as the circuitry used.
Should i try going back to a stock rom? Has anyone ever experience an issue like this?
Thanks!
Could it be gsm interference from your phone??? Sounds like typical gsm radio interference on your speakers.
I have the a500 not a501, so there is no radio in it to send GSM signals.
However i think what your saying is its interference from my cellphone, which is a captivate and does have a gsm radio.
Is there a way I can check if this is the case? Now that i think of it, my cell was in my pocket when I was noticing the problem. I guess i will try having it really close, see if theres a problem, and then really far away.
Thanks, i'll report back in a bit.
Is it possible that a speaker is blown? Or that the volume is up to loud? When my volume is turned up even to 75% it makes a crackling noise.
HI there guys.
Brand new to this forum.
I've searched for days and I'm unable to find a solution.
I'm experiencing a crackling or a distortion on phone calls at certain volumes. I noticed it with certain pitches in peoples voices it would cause a vibration in the ear speaker and some distortion in the sound. Kind of like the speaker is being over driven or has too much power going to it. It usually goes away if I turn the volume almost all the way down, but this is obviously not a practical option since I'm not always making phone calls in a dead silent room. The speaker phone works fine. This only happens when I'm using the earpiece. Is this normal? Is it related to the camera autofocus sensor rattle? Are the sound vibrations from a person's voice enough to set off the rattle? It's really annoying as I tend to make phone calls a lot and I don't like using speaker phone or a headset. Does anyone else have this problem?
From what I can tell, it happened and was normal in the S4. (http://forum.xda-developers.com/showthread.php?t=2280930).
Please help. Im deciding if i need to return it.

It's too bad that you didn't describe it in more detail.. i.e. give us steps to replicate it. A recording of the distortion would have been helpful too. I haven't noticed what you describe but it sounds like the gain or auto gain is too high and your earpiece speaker is being overdriven.
There is a gain setting in the service mode menu but first you need to distinguish an app issue or possibly damaged speaker before messing around in the hidden settings. See if you can find an audio app that will give you a wider adjustment range for your system volume and gain.,

Thank you for the reply.
If you go into the service menu, the go into the low frequency test. At 100hz and 200 hz there is a little bit of buzz in the headset reciever unless you really push it against your face (which i assume kind of tightens the spaces in the plastic and prevents whatever vibration in the speaker is occuring).
Hmm.. the vibration is akin to as if you were speaking into some cellophane wrap; like some film (maybe for waterproofing) is covering the speaker.
Oh. It's also worth noting that I cannot replicate the issue on Skype or Viber. Those sound crystal clear.
Bump. Anyone?
I didn't noticed this before, so I'm not sure if its due to the Nougat update or its just the "normal" way the speakers work.
I was watching youtube and the phone sounds ok when the volume is set above 40%, after that its to loud to notice the "scratch" sound I hear when the volume is really low (on speaker, not headphones).
Has anyone noticed that? I don't think is a big deal since it's rather unnoticeable in normal conditions but I wonder if it's just my phone or what.
Lower quality speaker. It is a budget phone after all.
You can download a sound equalizer and play with the frequencies a little to see if you can tone the frequencies down a little that are causing the distortion.

Yeah, I find it hard to believe its a budget phone, for me it's an expensive phone :angel:
I should point out that the only way to notice the scratch sound is by lowering the volume and placing the speaker close to the hear (I know, not healthy right?)
