A2DP still subpar in JI4 Eclair and JP3 Froyo.

In case anyone was curious, A2DP really doesnt sound any better between these builds. I'm starting to give up hope, maybe it's just my phone. The sound quality difference is night and day between my Vibrant and the myTouch 3G I have. I've tried on both my Kenwood head unit in my car and a pair of bluetooth headphones so I'm certain it's not the device I'm pairing with.
Ugh, just needed to vent, thanks.

pardon my ignorance, but i keep reading about A2DP and I finally want to find out what it is.
What is it?!?! thanks!!

A2DP is a bluetooth connection profile that supports high quality stereo audio. In the Vibrant's case however it is far from high quality. I was finally able to try another Vibrant today and it sounds just the same so now I know it's not just my phone. Some songs actually pass as decent bust most have a scratchy sound in the background and just lack overall depth. It really sounds like the bitrate is set too low on the Vibrant. Sabotage by the Bestie Boys for example has constant background noise/distortion that is not present when listening with wired headphones.
I've been digging around and swapping files around with the Korean Rom that has a supposed fix but I haven't made any progress.
One of the reasons I'd really like the Vibrant to sound better is because my Head Unit in my car supports A2DP. I have an app on my Vibrant called Tasker set to automatically fire up Pandora when a bluetooth connection is detected. So basically I can start my car and have my phone automatically start playing Pandora through my stereo, I can even advance songs with my dash controls. The audio quality can make it difficult to enjoy, My wife's myTouch3g on the other hand sounds superb on this same setup.

thanks for the response. i don't have a bluetooth set so that's probably why i haven't noticed this.

It really gets me down that my GPS, Compass, and A2DP are all broken on this phone. I'm gonna try and hold out for another month on a fix. If they released it in Korea hopefully they will release it here. Maybe I can talk Eugene or another dev to look into it
Audio quality is one of those subjective things and I really think a casual listener might not notice the problem but once you do you can't ignore it.

Strange, my BT sounds great streaming music through A2DP. I'm just on the stock Eclair build and streaming music through a Sony BT receiver, MW600. It's not an audiophile solution, but pushing music through some high-end IEMs sound perfectly fine for mobile listening. Maybe your hardware is bad?

I've tried two different Vibrant's on my car stereo and a pair of Bluetooth headphones and the results are the same. Again my wife's mytouch3g works perfect on both devices, maybe I should trade her phones . I've also tried an iPhone4 with excellent results.
Someone has actually opened a bug report with google on this very issue so I know I'm not alone in what I'm hearing:
http://code.google.com/p/android/issues/detail?id=9888
There was also an update for the Korean version of the Galaxy S that improved A2DP quality. This confirms that there is probably an issue that has not been addressed with our phones, since there have been no updates for Tmo customers.

Hi jz9833, what bluetooth device are you pairing your Vibrant with? Also what firmware, music app, file format are you using?

Have you considered going back to the stock ROM?
BT on mine is virtually identical to the headphone jack output. With Ety ER4p I can detect a little bit of digital hiss, but it's not really noticeable in a mobile environment.

Just today I tried a friends brand new out of the box Vibrant and I could still hear distortion/crackling at high frequencies. I then paired my headphones to my other friends iPhone4 just seconds after testing the new Vibrant and guess what, no distortion.

Man, I don't know what to say to you. My Vibrant sounds better out of BT than my iPod does out of its headphone jack. What BT headset are you using? For some strange reason they may just not get along. I've got a Sony MW600 and it's fantastic.

There is no word on if this fixed it or not and according to your link this has nothing to do with Samsung.
Look, if you don't know that Samsung has acknowledged GPS by now, has already fixed the compass in the JI4 series you mentioned in this thread, you should just jump over to Android 2.2 and it's problems.. sounds like you won't be getting a fix either way according to your own links

The first link confirms that other Android devices are having the same issue. Again my wife's myTouch3G doesn't suffer from the problem so I think it could be a simple bit rate setting that some manufacturers are overlooking.
The second link confirms that there is an A2DP problem on the Samsung Galaxy S and a fix exists.

No it doesn't. You don't know if the "fix" is not a "fix". The myTouch 3G has Android 1.6 stock and if she hasn't changed it, it's still running Android 1.6.

I'm not sure what point you are trying to make, I still hear the distortion on a bone stock Vibrant. The reason I tried these beta builds was because I was hoping that Samsung would have incorporated the A2DP update. And yes the mytouch3g is running Android 1.6.
What does "You don't know if the "fix" is not a "fix"" mean? I think the fact that Samsung released an update for the Korean Galaxy S that improves A2DP quality pretty much sums it up, there was a problem and they fixed it.
This reminds me of the Oscar Rogers skit on SNL, "Sombeody needs to look at this mess and fix it!", lol.

This is true, I have no idea what the A2DP fix does besides doing what Samsung claims it does, improve A2DP playback quality, which is exactly what I want. What is your point again?

Bluetooth audio still sounds poor on the new JI5 build. I've tried on three different Vibrants and three different bluetooth audio devices and have had others hear exactly what I hear. My wife's exact words, "Your phone sounds like a radio broadcast and my phone sounds like a CD."
I spoke to Samsung and they acknowledged there was a problem and said it was due to my devices not being Bluetooth 3.0 compatible. To my knowledge you can't even buy headphones that support 3.0 yet. I really wish they could fix this, I really like the phone overall.

[Q] Bluetooth A2DP and yamaha

I think I will get the note eventually either way, but I would like to confirm this:
Will using a bluetooth A2DP headset bypass the low quality yamaha DSP that everyone seems to be complaining about?

Hey bro, I moved to S2 after X1. I am tempted to get one and my hands are itching. I may buy one in Dec when I back to HK, or wait a little while for little lowered price.
I think volume+ only boost the volume but do not solve the problem of bad music quality of Yamaha chip (the same issue I found on S2). But I found music thru A2DP (SE MW-600 and JVC KD-BT1) are pretty good.

hopefully today (given up on lying couriers, going to collect it in person) I'll be able to actually have a listen..
although I wouldn't consider myself an audiophile, just a musician
volume+ does seem to help with eq, I've been using it on my streak for a while, but its mostly boost rather than anything else.
I guess its time to I started looking at the kernel..

Handsfree (cabled) problem with nexus 4

Hi all,
Got my nexus 4 last week - very impressed with it (then again (as my username says) i came from Sony X10/Arc land so a big improvement was easy!)
Having problems using handsfree on the phone - i'm using my existing handsfree cabled (3 bands on connector).
If i plug in the headset before making a call and dial someone, the call instantly ends and goes to google now
If i make the call and then plug in the headset, the quality is genuinely terrible.
Anyone else have any experience with this? Call quality without handsfree is genuinely perfect...
Ta in advance.

I am also unable to use my sony headset with n4 and was searching for problem.
whenever I connect it opens googles now and sound quality is clear only if I keep the button pressed on my headset. Can you check if the same case?
I am finding someone with same situation. I want to know if this is problem with sony n4 match up?

Hi Ksavai,
Thanks for the response. I don't have the headset with me now but will check later...
I also have a sony headset (MH-500) so maybe should test with another. Would like to know that no one else has this problem though before i spend money on another brand/model!

Checked my phone tonight.
With the sony mh-500 headset, i now get volume through the earphones ok but the audio level is very low; when i press the handsfree button the audio level increases dramatically.
Really is a crazy problem!

Hey,
Is this just a problem for some users? I would imagine that it would be a much more reported problem if it was the case with every phone. Or maybe everyone else is a blue-tooth-er

I am having the same problem with samsung handsfree. Actually I tried two sets. One had this issue and the other one just didnt work.
Is there a list of tested handsfree headsets?

After lots of searching I found out headset prior to 2011 won't work as it was different standard now it is updated standard. (I forgot the name but if you are interested I can look that up for you)
Newer galaxy s2 onwards or 2012 and later will work.
Newer one comes with grey or white circles on on pin while older ones have black.

I 've read about a ctia standard, but none of the products in eshops says whether they are compliant or not. There are also headsets with green circles in the pin...
I guess I should look for sony and iPhone compatible headsets.

2012 Sony line up was compatible

I was having the same issue and I found this: https://code.google.com/p/android/issues/detail?id=41860 I've used three different headsets: Samsung, Skullcandy, iPod headphones (newer model and the low mic problem persists throughout all of them).

Generic & Nokia earphones have voice cancellation! Hayyyylppp

No need to tell you guys about what rom kernel mod I'm using since I tested it on an unmodified Galaxy Y and it has the same results. And I don't know where to post this.
Please help me guys. So I bought a cheap generic low quality made-in-China earphones from the nearest mall. We're poor (kinda) and we really don't like to spend big amounts of money for these accessories. But seriously, I won't buy an earphone even more expensive than my device.
I brought it home and listened to some music. Voices were cancelled, like I can only hear the chorus and other sounds which are frequency related (maybe). I tried listening to a song made in 2008 and it was fine, I just had to increase the volume.
Then I discovered this secret button (lol) which was in the middle of it. I pressed it while listening to music and guess what. It now plays normally. I released my finger and it went back to voice cancellation. So literally, I have to press that button for 3-5 minutes when I want to listen to a song. I returned to the mall and asked for a replacement, said what my problem is, and they gave me a Nokia one. Sure the name is pretty reliable even though it's pretty old. Haha.
I listened to music while on the mall, I thought it was fine now and I hear everything cause it was just noisy there, I didn't notice that it had the same button (actually it's a button for skipping track, if plugged into Nokia phones). I brought it home, and I realized it was the same. I tried it on my brother's phone (Galaxy Y) and it was the same. I tried it on my sister's Nokia phone and it was working perfectly.
Now, my question is, how do I disable this? It seems to react that way when it's plugged into an Android device. Are there any workarounds?
Any suggestion is highly appreciated!

Update :
I experimented with the jack, I kinda loosened it a little bit, I think I found a point where it plays the music normally. So it works half plugged. Is there something I'm missing? :S

you could just go get a refund and buy a plantronics m50 bluetooth headset, i got mine for about £35/$53 no connection issues, no plug compatibility problems and wireless. now even works with "google now" (press ear button and speak to google from headset) as well as streaming music

Erm..I don't actually like a bluetooth headset since first of all I need to have my bluetooth on all the time, so it drains battery. Secondly it's only on one ear, I can't stand that. Is there a bluetooth headset that has both and is totally wireless?

yeah you can get bluetooth set with both ears, just search stereo bluetooth headset, i would definitively go with plantronics.
the brilliant thing is after setting up "bluetooth launch" with the tab in my backpack i can still ask google now questions without getting off my bike via wireless.
"play music"
"whats the weather like today"
"navigate to *****"

Is it possible to have dual audio bluetooth output like s8

Now that android pie has arrived that do support connecting 2 devices at the same time but there is no way that we can play in both bluetooth speaker at the same time like s8. Maybe it is a noob question but this development will be very beneficial

I was hoping for this feature in Pie aswell since there were many articles in the internet saying that it should be possible to connect up to 5 devices at one time. But it seems like there is no way to get this running .
