Is anyone having issues with 'tinny' and distorted sounding audio while streaming via A2DP? I'm using a Blackberry audio gateway that worked flawlessly with my old G1 but with the Vibrant I find the audio quality so appalling I can't even listen to it. It's definitely not a question of the volume settings being too high. It also does this for EVERY program so its a global problem, possibly with the bluetooth stack. For now I'm coping with the 1/8" jack but thats starting to drive me nuts.
Anyone experience this? Is there a way to force the stack not to use A2DP or other protocols?
Yes A2DP sounds bad for me as well. I'm using a kenwood bt-200 made by parrot for my kenwood head unit and the audio is distorted at higher frequencies and it's missing a lot of mid bass. With my wifes mytouch the same setup sounds excellent.
Samsung released an update for improved A2DP streaming in korea so maybe well see it here as well? Like you I've just been using an rca cable for audio because A2DP is simply unusable with the Vibrant.

The more I listen to it the more I think its a volume/clipping issue than an encoding issue. Thank christ I'm not alone I was beginning to suspect I was being a whiney brat about the quality.
I just tested the gateway with a third phone and it also works flawlessly. Getting frustrated...

So does anyone have experience extracting files from Samsung .rfs files? I'm trying to do so via adb and failing miserably. I'm hoping to snag the new bluetooth.apk from the 2.2 developement build from Samsung to see if it has the sound quality updates.
Anyone?
I'm trying to determine if it's just the crappy TouchWiz Music Player they replaced the default Android player with. When I stream from other apps it sounds noticeably better (like Last.FM or Pandora), and I tried the Cubed player for a comparison of MP3 audio and it also sounded better.
Have any of you done a comparison like that?
I carried over the heavily modded cyanogen music player and besides that I use slacker. Still sucks.

Yep pandora, slacker, and the music player all sound terrible through A2DP.

Phone fell on it's face when trying to use the experimental bluetooth files. Wouldn't boot or respond to anything. Going to restore my nandroid backup and call it a night. Looks like we'll have to wait for the update...
If anyone can offer some more insight in regard to what I should do with the files please let me know.
It looks like the Vibrant isn't the only Android phone suffering A2DP quality issues. Please vote on Android issue 9888 if you are experiencing subpar A2DP audio quality from your Android device!

Thanks for the heads up. Honestly sounds like a Bluetooth 3.0 issue with android now. Just shocked so few people are complaining.

I am running the desensed honeycomb ROM and have no issues with the audio when using plug in headphones or the devices speakers. But using Bluetooth headphones with Netflix, I get a five to ten second lag on the audio. Is anyone else having this issue? If so, is there a fix. It seems that the tablet is working rarely hard trying to keep up. Maybe its underpowered?

I am also experiencing the same problem, i called netflix to let them know of the issue. I am on a Galaxy Note. you should call them at 1-800-585-7265 so they can be aware of the issue
I think this issue isn't related to Netflix. I experienced the same delay (~3sec.) thru bluetooth on all my Android devices (Liquid E, i9000, xperia play, atrix, ideapad k1)
Try watching a video on the stock video player... I noticed a delay in that too (on the Atrix)
My car bluetooth is really annoying seeing that I press the skip button and have to wait before it actually skips to the next track...
Here are some threads showcasing the same issue:

I haven't had any issues until this device. I have a transformer, galaxy tab 10.1, razr, thunderbolt, incredible, og droid. I thought that perhaps the CPU isnt strong enough. It struggles just trying to play it without Bluetooth. Does this tablet support hardware acceleration?

I've had similar issues with Netflix on a Galaxy 8.9, Galaxy 7.0, and an Acer Iconia A100. The BT headphones I have work great with my iPhone and iPad -- no lag whatsoever. It hasn't been just the Netflix, but virtually all video apps.
When I did pair my BT headphones there were 2 ways to pair it (headset or headphones). After I found that setting, it dropped the lag from about 5 secs down to about 1 second. Still too disconcerting to watch a video though.
The Acer Iconia A100 has been the best so far. It actually played YouTube vids without a lag (the through the app and the browser).
I thought the issue was 3.0/3.1, but Iconia is 3.2. I'm going to see if ICS makes any difference.
(Side Note: I found that at least one of the Galaxy tabs uses the same BT chip as the iPad so that's probably not the culprit.)
its not the CPU or the ROM, or the app and it won't be fixed in ICS. Its a artifact of the Advanced Audio Distribution Profile (A2DP) Bluetooth protocol. It buffers a couple of seconds of audio before it starts transmitting because when it was specd. they intended it only for music playback. Now it is pressed into service for video audio and there is no way to sync the playback. Perhaps more advanced players will arrive on the scene someday and allow for adjusting the timing. something like VLC maybe, but for now, you can't fix it.
To me it only affects crackle and netflix. By the way other devices like galaxy nexus does not have this problem along with other phones. What ever it is it must be our bt drivers of our Notes

The built in codecs "attempt" to compensate for those formats that they support. Since Netflix is propitiatory, that does not work for Netflix, its an application problem.
Hat makes sense. I called netflix and tried to tell them of the issue

By the way your explanation is bunk.bunk.bunk.
I upgraded to ICS and the out of sync is no longer there. Netflix is same exact version. sorry dr. quack. I knew your explanation was fishy
Sent from my SAMSUNG-SGH-I717 using Tapatalk
Regardless if his explanation is accurate or not, what's true is that it's a common problem for Bluetooth to lag and not sync the audio with different video applications.
It doesn't just happen on the HTC View, and it doesn't just happen with netflix.
I haven't researched why it happens, nor do I have any suggestions on how to fix it. I just know it's a common issue.
While I'm not sure if DigitalMD's explanation is 100% accurate, I'm inclined to take his word for it. It was the way Bluetooth was designed, and it truly wasn't intended to be used for videos. The reason it might appear more obviously in our devices is due to the use of Bluetooth 3.0? I really have no clue though, but it's a thought!
Its the Bluetooth stack or drivers in our device. what else would it be? After upgrading to ics, all.of the sudden it works. other phones i had didn't have this issues before.

That's probably exactly what it is. Other devices may have drivers or software that can compensate for the lag. I have had the problem on other devices but not *every* device. I'll actually be able to test my thunderbolt tonight to see if it has the same issue just because I'm curious
EDIT: yup, lag exists on thunderbolt too

From what I have gathered he is correct about the problem being in the BT stack. Even if he is wrong there is not reason to attack him and be so insulting. That makes you way more wrong than he may be.
Here are my own experiences with Android and Bluetooth audio.
Some video material itself has an inherent lip-sync issue that will show up no matter what you play it back with, so you have to rule that out. However, there is also a known lip-sync delay bug with the Android Netflix client and Bluetooth audio devices. I have tried the following Android devices:
Samsung Galaxy S4 (Android 4.4.2)
Nexus 7 2013 (rev2) (Android 5.0.2)
Hisense Sero 7 Pro (Android 4.2.1)
with the following Bluetooth audio devices:
Monoprice 11947 On-The-Ear Headphones
Monoprice 10585 Premium On-The-Ear Headphones
Creative D80 Portable Speaker
There is a significant lip-sync delay (anywhere from 1/4s to 1/2s) with the Android Netflix client with all combinations of these that I have tried. With these same Android devices and Bluetooth audio devices, the following apps play back perfectly with no lip-sync issues:
Amazon Video
Hulu
TiVo Roamio Streaming
YouTube
Native Android video player
Other Android apps (games, etc.)
The only combination with a lip-sync delay is the Android Netflix client with a Bluetooth audio device. Wired headphones are fine. I also tried the iPhone Netflix app with the Bluetooth audio devices and that plays back fine, so this is a problem only with their Android client.
Bluetooth itself has a 3ms latency; the delay is not a Bluetooth problem. In games with sound effects, they happen immediately through Bluetooth audio.
I called into the Netflix customer service department so many times. Every time, the same script - clear the app cache, restart the Android device, charge the battery in the Bluetooth device, power-cycle the router and cablemodem, unpair and repair the devices, etc. Some customer service reps told me it was normal Bluetooth behavior (it is not - the latency is 3ms), most told me it was the Bluetooth interfering with the Wifi connection (wat?). I repeatedly explained my testing results (long) and how it entirely points to a software issue. After many calls, I begged the rep to contact the next-level support to report this as a bug, and finally got confirmation that their Android client "has some issues" with Bluetooth audio, but no mention of a fix.
So there you have it. Call into Netflix customer support, repeatedly! Maybe we can get them to fix the problem.
I have a jvc deck that has built in blutooth. It routes the sound they the car speakers and uses a wired microphone. Call quality transmit an receive is pretty damn good. However, when using bluetooth audio...say pushing anything from the music app, or pandora, there is alot of static attached to the signal. Does anyone else have this problem? Are there any solutions. I am rooted but still stock. I use poweramp as well as the default player at times.

I have a jvc deck as well, and I don't have any problems with static over bluetooth. I use Pandora and Google play music, and both work great for me on stock, CM7, CM9, and MIUI. MIUI actually works the best for me as far as bluetooth playing nice with the head unit.
Never used power amp or stock tho, so I can't speak for that.

Thought I really hate the annoying noise when I use the wired earphones.
Ill have to experiment with a few other players. I rarely use the phone for streaming in the car. Odd, I really dint pick up any noise with wired cans. On a side note, I found a new player 'neutron' that blows away anything I've used this far in the sq department. Its a paid app that offers a limited use 'timed' trial.

Similar issue
I've also got a semi-stock Photon 4G. Been using it fine in my Ford Fusion w/ Sync. Sunday, tried to make a phone call and it was just static. Turned off the bluetooth on my phone and it was fine. Now, it's unable to make a call through Sync. It pairs fine, just nothing but static. Why the sudden change? No new updates from Motorola or Sprint that I'm aware of. BTW, by semi-stock, I mean it's rooted. No custom ROM's or what not. Any ideas? I've googled some and it seems that the Photon 4G has some bluetooth related issues. I really like the phone and had really planned on holding off on upgrading since there wasn't a real 'need'. Another issue I've had lately is receiving texts w/ no sound. It vibrates, but doesn't give me a sound. I checked the setting and even when scrolling through the notification sounds, it doesn't do it. Then it will randomly do it. Rebooted and battery pulls have been done. Really, REALLY don't want to do a reset. Ideas? Are they related?
I use bluetooth audio everyday, and I've used every rom except stock. Bluetooth always works very well. Rule out your jvc device first, test your Bluetooth on something else. Then reset or reflash, then use your warranty.

I also intermittently get static when making calls in my Focus via Sync over Bluetooth. I can faintly hear the caller in the background, but the static is MUCH louder than the person. When this occurs, there are some other symptoms the phone exibits:
No audio will play via multiple apps. Tested in Pandora (cycles from one song to another), Amazon MP3 (same as Pandora), Youtube (Gives an error about audio), Voicemail (Unable to play the message).
Alarms only vibrate, no audible alarm.
When trying to do a call via speakerphone, the person on the other end cannot hear me.
The fix I have found is to reboot. The phone is stock, but has been rooted, and has occurred for the past few months, even with the update that came out at the beginning of August. I tried reflashing it in June with the 198 SBF, but didn't do a reset of the data. The reflash succeeded, but the problem is still occurring. I removed "Words with Friends" and "Scramble with Friends" last night to see if it helps.

Rats. Too bad I hate Sense, so I'll probabpy go with a Galaxy S III, even though I dont like TouchWiz. However, Touchwiz is preferable to Sense. Might go Galaxy Nexus, not sure. For now, haven't had it reoccur yet, but we'll see.
Good news: not a single reoccurance of the static over bluetooth and no audio. I still wonder how an app can effectively crash the audio stack, though. Oh well.

not every bt car audio system has the ability to stream music, just because you can make phone calls through it..
does the owners manual say that you can stream music from any android phone through it?
you might want to contact them and ask them directly
Yes, I actually bought it for the android streaming ability. I figured it has to be my phone since I can not make it do that any other time. Just curious if anyone else has had an issue like this.

I just upgraded my Rom to the Jedi XV12 rom without issue. Currently I'm experiencing a "silent" audio when the phone is synced to my car via bluetooth BT and trying to listen to Pandora. My car has the Pandora app and prior to this ROM I did not have the issue. I "turned" the volume up on the phone and it showed the BT audio at max... yet there was no sound. Is there something else I need to do or update on the phone?
Check the settings on your paired Bluetooth device and make sure media audio is selected. Otherwise I'm not sure. You might try to delete the device and re-pair it.

What music app are you using ? Did you try a different one ? I'm using Subsonic and I'm having issues with eq's.
My audio work with my Bluetooth in my car neither the in app nor Beat's eq's work. I did not have eq issues with Bean's which I'm probably going to switch back to.
Looks like Google Music app works with Beats so for me it was the app I was using.
Well, according to the thread title, [Q] BT Audio / Pandora / Jedi XV12, looks like he is using Pandora.
Interesting enough..... If I have BT Audio enabled for both Phone Audio and Media Audio.... ANY BT audio does not come through the BT device. If I uncheck the Phone Audio.... it plays just fine. The Controls for the player work fine in either scenario... just no audio if the Phone Audio is checked. I have had intermittent success by having the audio going.... unchecking phone audio... listening for a few... and then re-checking phone audio. Sometimes it will keep playing without issue.... other times it "mutes" the media audio even though it is checked.
Did I confuse anyone.... LOL

Neo CM10.1 rom + IHateWebOS latest test kernel + power amp music program = ear orgasm.
Sounds a lot better than any stock sense rom i have heard so far.
but it also depends on the equipment you have, what settings you have, what you like to listen too, ect.....
Using Vigor360 still. But Sense 3.6 and the Beats mod sounds great. My only complaint is that the Play Music app sounds horrible on bluetooth. Using the headphone jack for Play Music, and any other app on bluetooth sound fine.
Hearing that the AOSP roms don't sound all that great makes me hope there will eventually be a 'leaked' JB update from HTC...odds are not great on that though.
This is easy. Get rid of any sound defects apps (HtcMusicEnhancer.apk, HtcMusicEnhancer.odex, HtcBeatsNotify.apk, HtcBeatsNotify.odex). Turn off any equalizer, or set it to "flat" if it can't be turned off. If your preamp doesn't have enough gain, get Volume+. A direct connection will sound better than Bluetooth. The only reason a ROM would make things sound bad is if it's screwing with the (raw/decoded, depending on the source) bitstream.
I just use poweramp and mess with the EQ a lot.
I use Equalizer with Pacman.
