A2DP is sounding scratchy

Hi
I'm a new user with an Excalibur which I bought second hand the other day and generally am fairly impressed with. I have had it unlocked and bought a 4Gb microSDHC Card and upgraded to 6.1 using Kavana's ROM remade by Ricky.
I do have one small problem though, the A2DP is sounding scratchy whenever I use it to play music. It's not like an interference scratchy, but the highs of the music sound clipped and very scratchy, especially noticable at the higher volumes which I am having to use because the volume also does not go especially high, but it's present but softer at the lower volume levels.
I'm using Coreplayer but have the same experience with WMP or in fact any audio application I use. The files are fairly good 320kbps encodes in MP3 and AAC which sound excellent on the computer and I have tried a variety of files as well as some Youtube streams, all with the same results.
The headset is a Sony Ericsson DS-200 which is the dongle type headset where you can plug in your own headphones. The headset and headphones combination again sounds excellent when paired with a Sony Bluetooth walkman and an old SE mobile phone with A2DP.
I'm guessing it might be drivers, or something? I have ordered a wired headphone adaptor but would really like to use A2DP if possible.
Finally, if this is fixable, is there any way to boost the volume? My headset does not have a volume control, but the Coreplayer etc. volume control adjusts the volume - it just doesn't go very high and I can imagine it wouldn't drown out, for instance, public transport noise.
Thanks in advance

Hi
Sorry, should have really done a search! I found this:
http://www.htcwiki.com/page/Tweaks+and+Hacks?t=anon
and tweaked the registry settings and it's sounding considerably better now. Unfortunately it seems to have introduced a bug where the wireless stereo headset icon no longer appears, all that appears is the standard headset icon (the one with the microphone on it) but A2DP is working so I can live with that!

thanks for the link, Ive seen this tweak in other forums but this one the directions were way easier to follow.

I cannot control the volume of Streaming Bluetooth Audio.... :(

I have a pair of bluetooth headphones and a bluetooth receiver in my car.
Once i pair either one to my Touch Pro 2, i noticed that raising/lowering the volume on my HD2 does not affect the audio what so ever(unless i put it on mute).
The music sounds very loud and distorted, and i cant control the volume either way...Anyone else run into this issue? How can i solve it?

That's normal. You need to adjust the volume at the receiving end.

I have the exact same problem. Not sure why as when I pair up to my speakers, the phone tells me it cannot control the volume, yet it worked fine on my "Touch Pro" (the 1st one) and my Kaiser. Not looked for a solution, because its not much of an issue for me really.

But the problem is that, the audio being streamed from the HD2 is so loud and distorted, that i have to turn it down(but i cant).
So even if i turn it down on the receiving end, the distortion is still there.
With my old samsung omnia, i was able to turn the music up or down from the phone...I dont understand why this isnt possible with the Touch Pro 2.
The music coming from my phone is unlistenable. The distortion ruins the audio. Which really sucks, because i spent $300 on a car reciever with bluetooth!
There has to be a solution! Come on XDA!

Try turning it down on the phone first? Or get a player that uses it's own volume control instead of the system volume (I believe Mort Player and Nitrogen will do this).

Same problem here!!!
No volume control at all on TP2, and volume of music cant be changed through the system volume control either

I have a bluetooth connection to my motorcycle intercom system. I had the same problem, sort of.
I installed Conduits Pocket Player, and use the equalizer to bring down the level of the Bluetooth. That worked well enough for what I needed to do.

I read somewhere else on the forum here that this issue is attributed to the Widcomm Buetooth stack on our phones. Whenever I connect my headset to my phone or my laptop, I receive a warning that the volume must be adjusted on the output device, and cannot be adjusted on the phone/computer. It may be related to the poor support for AVRCP.

ok, so it seems that this wincomm bluetooth stack or whatever SUCKS. You're right....I guess the only work around i guess is a player that doesnt use the system volume, like coreplayer.
Coreplayer is great for movies, but for playing mp3's i would prefer Slide 2 Play.
Havent tried nitrogen yet though.
Does a mp3 player exist that is similar to slide 2 play, but doesnt use the system volume of the phone?

I too am not able to use many of the bluetooth audio accessories such as my jabra headphones, desktop speakers and my indash audio system. None of which work as they did with my Kaiser. This was supposed to be an upgrade to my Tilt and it doesnt even support the OLD protocals that were common 2 years ago?? Im seriously considering switching to blackberry. Anyone intrested in a nearly new Tilt 2. Goodbye htc (high tech crap)

THis is a problem with the bluetooth stack, just email HTC so they can get a patch for this. or microsoft because they are the ones that control what stack it gets.
this Goes for the HD2 and others too

Bluetooth audio.

Has anyone figured out why high frequencies get garbled since the EG30 kernel? That's the last one I remember that did not garble. From what I've been told, the bluetooth stack is built into the kernel, not the ROM.
Could someone please clarify and perhaps offer a solution?

How about very low volume on the BT ? I paired my phone with the BT in my 2012 Ford (with SYNC) and the music plays perfectly, but I can't hear S#!T during a phone conversation...

I have a 2011 Explorer with SYNC and if memory serves, it considers the BT music volume and in-call volume 2 separate things. Once a call is made, you have to turn up the volume again to get that where you want it. Once it's turned up, it stays that way.

I'll try that but then I'll have to remember to turn it down when switching back to SiriusXM so that I dont blow my ears out.

I turned the media player volume down to 10 (as opposed to the normal 15) and it's still static on the high end.

Everything except cyanogen sucks as far as the bitpool goes and low bitpool makes bt sound like ****. I love android so much but I'm soooo disappointed in the amount of attention paid to Bluetooth sound. It's fine for audiobooks or podcasts but sucks for music.
Actually my son has a nexus s unrooted, maybe I should check that and see if music sounds OK. Maybe pure Android doesn't suck its just the touchwizs and senses of the world that make it terrible.

Wow... I was debating getting a Bluetooth speaker today. Didn't realize there was an issue like this with our phone.
Thanks for the insight. I wonder if any dev could do anything about this.

I have had a very different experience with in-car bluetooth audio. I just installed an iSimple expansion kit (uses the factory harness/plug and play) into my vehicle, and it sounds excellent! I have the phone volume turned all the way up, changing the level on the stereo instead. It seems to me that it isn't any quieter than XM, FM/AM, or CDs, and I like having all my music in Google Music and Pandora instead of the giant case of CDs I used to carry around. The call quality is average, better than OnStar if you've used it, worse than a call with good signal. The person on the other end sounds great, but I've heard that the driver always seems quieter than through the phone mic. My friends bluetooth audio in his Kia Soul does not sound as good as mine does, but the call quality is sometimes better.
Anyway, just my 2c. Cheers!

I have been using bluetooth audio and phone calls on stock rooted EL29 ROM with the Rogue Gunslinger kernel in both my car as well as a pair of headphones, and the audio comes through crystal clear. The car has a Kenwood KDC-BT945U head unit that supports A2DP and AVRCP, as well as hands-free calling, and I have no problems with either calls or music streaming. In the home, I have a Logitech bluetooth wireless speaker adapter plugged into my AVR, and it also sounds perfectly clear. There is never a hint of hissing, popping, dropouts, etc. I suggest that anyone who has bluetooth issues try my rom/kernel setup. If it does not work, you can blame the Ford or whatever bluetooth setup you have because the phone itself is perfectly good at bluetooth audio streaming. Maybe not out of the box, but with my setup I have no problems. For the record, I have high-end (near audiophile grade) audio equipment in both my car and home, so I know what good music sounds like. One caveat though, don't expect bluetooth streaming to sound as good as a wired connection. There is quite a bit of compression going on, but the difference is barely discernable in the car, probably due to the road noise. In the home though I have much higher quality speakers, and I can perceive a larger difference, but unless I'm listening to classical music in FLAC format, it's negligible.

Bluetooth audio on MyFord Touch is flawless..

I have noticed the crappy quality as well.... but here is some good news... they fixed it with ICS. I'm currently running the FB17 leaked build, and the quality is PERFECT. I'm an audiophile, so I pay close attention to the sound quality. and am very very happy the addressed this issue in ICS.

I have to agree, I have uConnect in my new Durango and was pissed when BT streaming did not work (it sounded like a constant pause/unpause and fastforward all at once). I just by happenstance tried it on FB17 and FB21 and it was perfect! Although the builds are not great yet so I went back to Calk 2.9 and itchin for a great ICS build to get that back!

The BT sounds very well for music but during a phone conversation, the volume of the other party is way too low. If you were to increase the car's volume to hear the other person, it will decrease your microphone's sensitivity to a point where the other person cannot understand what you're saying (to prevent feedback)... It may be my FORD SYNC, but it worked beautifully on my old Blackberry. I will wait for ICS update and hope they addressed this problem.

Thanks!

I sure hope you're right! It's so much nicer to use my steering wheel controls then to reach over to my windshield-mounted phone and push the tiny on-screen buttons with Google Music. I'm also an audiophile and couldn't take the low quality sound of BT-Audio. Thanks for the hope!

I was on Paranoid Android 2.16, I used the Bluetooth music and calls in my 2012 Civic Si and sound quality was perfect. I switched to FI27 to give it a try and the Bluetooth sound quality went to crap. Has anyone looked further into the kernel theory? Anybody know a good kernel to use with latest update? That can be pushed with Odin? Thanks for any updates or suggestions.

anyone play music in their car with this and have it NOT suck?

Wondering if there's a secret. It's like everything below 200mhz has been removed, both through headphone jack and bluetooth.

Sound quality for me both on Bluetooth and headphones is great

Sounds good to me

Same here. Good quality in car whether i use my bt adapter or through audio jack.

Using Vanilla Player to play local mp3s sounds good on my headphones. Maybe a little "small" on my BT speaker, but its a small cheap speaker. Haven't noticed poor quality in my car.

I do use bluetooth pretty much exclusively in the car. I have a pair of headphones that sound really good with the phone. Dont use anything else to play music but I do sometimes have problems with the headphone jack when I move the cable around.

The sound quality when connected via cable to my car stereo or headphones seems to be fairly decent, though a bit noisier than the audio I get from my iPhone. I still have the problem of losing audio on calls after disconnecting from the audio jack (I can't hear callers on incoming calls and sometimes callers cannot hear me when I call them) and then having audio not re-routed back to the audio jack the next time I connect. Because this has happened on more than one Fire phone, I just use a cheap Bluetooth USB adapter connected to my stereo which does degrade the audio quality somewhat however.

Do you guys use any sound processing apps at all? I seriously have no bass coming out of my phone. I turn the bass up almost all the way on my car stereo, and in an EQ app for the phone (tried without the app too), and it's still not quite what a normal mp3 playing directly on my car receiver sounds like.
I'm on fire OS, are any of you on cm11?
Also this uses dolby or something doesn't it? I worry that something I've disabled has messed it up, but don't know what it would be.

No sound processing apps for me. I'm usually on Fire OS 4.6.3 rooted with no Google Play services. Now I'm on 4.6.5 unrooted (trying to resolve a GPS issue) and it sounds the same over BT.

Works fine for me too. Hardwired through AUX or with Bluetooth. Headphones/earbuds sound good too. I mainly use Amazon Music player, Google Music, and Pandora.

I've had no problems with BT connection from my Fire OS Fire Phone to my Sony receiver. Bass response is good whether or not I am running "Equalizer FX." I use Equalizer FX because the bass on the car stereo (and my headphones) rolls off below 60Hz.
I have learned from other phones that running the volume at max level can cause clipping and sound degredation.

Question Usage of Razer Kraken Over-ear wired on Pubg Mobile, Poco F3

Using the headset for the first time and I can see a notable sound reduction compared to gaming with a mi mix 3 5g I had before. I dont have a second wired headset to compare.
Any idea what could be going wrong? I have ultra sound enabled in-game. I also downgraded from that and the issue remains.
Comparing with Razer Hammerhead True Wireless I have, the sound is really loud on the second , so something is definately going on with the first headset interaction with the game.
Listening to music or doing anything else seems the same as before so the possibility of headset malfunction is out of the table.

Yes done already. Still the same.

The only difference I can find from my previous xiaomi Device is the addition of 24-bit/192kHz audio. Thats for wired Audio?

Me too facing this problem, when i use in ear earphones like i have jbl, the sound output is loud and clear, but when i switch to hyperx cloud stinger headphones, the sound output becomes very low, this case happens only in games, music youtube etc. have loud sound output, if anybody knows the solution of this problem please tell us.

Oops Wrong thread.

Wrong thread why? Wrong Device?

But really hoping I can find a solution. Even if I sell my headset how can I be sure the new one I will get will perform as it should?

have you tried to remove "improoved audio" from the turbo videogames settings? have you tried using a pair of in ears. if the in ears are at "high volume both in games and not. the problem resides in the internal amplifier. you can buy a more powerful cabled or bt adapter to solve the problem

I have turbo turned off. Should I turn it on? Also my brother has some other jbl over ear wired headphones. Going not to check if the Audio is the same with those and coming right back here.

Out of curiosity i've tried a few pair of headphones with the adapter. The phone had enough volume to drive a pair of Beats (32 ohm) at 60% and a pair of dt990pro (250 ohm) at max volume. Id doubt the problema comes from the headphones used. Try to check under soud assistant if you have the "mixer" enabled or disabled. Maybe you've lowered the volume of that single app

I opened sound assistant, it has 3 options and the third is turned on, the first two are turned off. One is for playing sound through multiple apps and the second for multiple sound sources.
