p3600 A2dp, crappy sound

The quality of music with A2DP is really bad, have much better sound with my qtek s110 with a2dp hack. I have been using the same sony ericsson ds970. Is there anything that can be done about it?

perhaps you can follow the instruction to turn on the stereo, then the sound will be better.

This is my experience to. I had a SE m600i before and the sound was way much better on that device.

The sound clearly suckes with the headset that is packet with the P3600.
The sound on the S100 was far more better.
Lets just hope the ATi chip get's activated on the rom-update, so that the Graphics and Sound get better.

guys, could you please be more specific? what exactly made you unhappy about the sound produced by HTC Trinity?
please define the problem. is it too soft, too loud, lacking bass or higher frequencies, choppy, etc, etc????
P.S. forget about stock standard wired headset supplied with your Trinity. it's bad.

ATI chip?

Guys try using the Hermes Registry Tweaker
I used the hermes registry tweaker to take BT Stereo sound from "Okay" to "Excellent" the tool has five levels of quality as well a tweak to enable true stereo rather than joint stereo.
It worked for me! You can unlock and mount EXTrom too.

It has a desturbing sound on the higher tones and the bas is muffled. I tried the fit4 program and changed to the best quality, it sounded a little bit better but it was hard to hear, beacuse now the music skips even more thnat earlier. You know you ger music for a while, it cuts of for a second and then comes back. Now it does this every 5 seconds.

just tested it here. seems to work. The setting was on LOW on my trinity.
I also tried to turn on the GPS settings, which turned on a nice little menu for configuration of the GPS. Looks promising if this is what we get
does not look like the settings gets any gps functionality to be activated besides the settings.

Excellent
Made a big diference on mine too! Nice to know it worked for you.
Try this to disable joint stereo so you get REAL stereo sound, then you will see the difference.

you guys might also want to check out the effort made to port the WIDCOMM stack onto the hermes (to replace the microsoft BT stack). the widcomm stack is superioir and the testers so far have indicated that sound on a2dp is great. the hermes and trinity are basically the same... so it might work.

Last time I tried the Widcomm stack the stack started well, but I couldn't see any bluetooth device. The blue-led did not flash either.

Can't find any bluetooth device.

3D surround configuration
On page 78 of Trinity's manual there is an instruction to set the 3D surround configuration at the headset by going to
Start> Settings > Personal > 3D Surround Sound
and enabling surround sound + setting levels.
I simply can't find the "3D surround sound" selection at >Personal tab...
Can someone help me to configure (eventually by using some registry configuration) how to make this command to appear?
Seems to me this could help to improve stereo quality at P3600...

The problem with my new p3600i is that the volume is much too low. With volume control at max setting, I can just hear music in a quiet environment. e.g. an empty room. When there is any background noise, e.g walking along the street, on a train etc, it is almost inaudible. I am mainly listening to classical music, so the dynamic variation is greater than for rock etc., but nevertheless very disappointing.
I am using the supplied headset, but the sound is not loud enough to know what the quality is like.
Are there any setting I haven't found yet? All the talk about changing the ROM sounds like something which might void the warranty
thanks

I have used HTC_UseJointStereff.cab and HTweakC, it seems that the sound changes a little, i don't konw which helps, but they help....
Thank you all.

[REQUEST] A2DP Manager

I'm using three different A2DP headsets: a Clarion deck in my car, Kyocera stereo headphones, and a Sony bookshelf system at home (I'm addicted to audio books).
To connect the "Wireless Stereo" profile on my Touch, I have to go to the list of bluetooth devices, "right click", and then select the "set as wireless stereo" option. Since applying the latest ROM on this phone, this option doesn't even work anymore.
I've found A2DPtoggle, which connects to the last connected headset automatically, but it takes two launches of the exe to do this (I'm not sure exactly how it works). This works awfully with multiple headsets.
Does anyone know of a solution to quickly connect to these different headsets? I've found with the headphones that when I turn them on, they automatically connect to the phone. I wish i knew why they do that, and the other headsets don't.
Also, I need the bitpool set at 10 to have the audio not skip on the headphones, but the other two headsets work fine on a much higher bitpool. It would be great to set a certain bitpool to each headset so I can have the best quality on each device. This sounds unlikely as I think my Touch needs a reboot when changing that value.

http://rapidshare.com/files/42718525/HTC_BT_Quicklink.cab
install, SR ,enjoy

did that, but what did it do?

update: after installing this Quicklink cab, the A2DP automatically connects from my car stereo to my phone, but only if I turn the bluetooth on while near the powered-on stereo. This also takes about 30 seconds. Manually doing it is much faster :\

Help! Bluetooth never connects A2DP Stereo automatically !!

Hi! This issue has plagued me ever since i am using windows mobile. I own a TOUCH HD (though i think this issue is also with other windows mobiles) and a A2DP Stereo bluetooth headset from Sony.
http://images.google.nl/imgres?imgu...ox-a&rls=org.mozilla:en-US:official&sa=N&um=1
Now here's the problem. When I pair the phone with the Headset, it pairs the 2 services HANDSFREE & WIRELESS STEREO. Then i can listen to music via the headset.
When i turn the headset off and then back on again, it switches on the HANDSFREE ONLY !! And i have to go thru the following process to turn on the WIRELESS STEREO again:
1. on phone, click on Bluetooth Devices
2. select the headset device to view the 2 services (handsfree and wirless stereo). Both are selected. Deselect the Wireless Stereo service.
3. SAVE
4. on phone, click on Bluetooth Devices
5. select the headset device to view the 2 services (handsfree and wirless stereo). Re-select the Wireless Stereo service.
6. SAVE
Then it works again and i can listen to my music again.
Its a very annoying process and I wish someone could help me to explain if there is a faster way? Does everyone also have to go thru this process or am i doing something wrong?
Does there exist a program that can automate this process or any other solution?
looking forward to replies!

there are more than one small app to make it easy.i found one that works on my HD. uploaded for you here:
http://rapidshare.com/files/207816065/13-BTaudioTransfer.cab
next time try and do a search....

thanks a lot! It actually works! cant imagine why microsoft creates an OS without this built in as standard !
thanks.

I have a same problem with my car audio, but when i install this BT program in lower post they connect me only to handsfreee, and when i go to play music they disconnected my car BT audio.

Just for you interest - this does NOT make A2DP work.

Mirror site please!!!

Can someone please mirror this download, my limit is up on.

Here is the source.

(sorry all, could not find an edit for my last post)

Pair your stereo headset and select the Heaset and Wireless Stereo profiles, this will work from start.
Next time you turn on your stereo headset it will only connect as standard headset (ie mono for phone calls)....
Just press the play/pause button on your headset and it will auto connect to A2DP stereo also.
Simple EH?

Tried that!
I have tried that, and do it on my laptop (another set and stereo profile only), it may be dependent on the headset you are using.
The Triangle Powers BT Stereo is mono output only, and made the audio quality poor on my HD. http://trianglepowers.com/PPC/ViewApp.aspx?ID=52
I installed teksoft A2DP Toggle 1.1 this morning http://teksoftco.com/forum/viewtopic.php?t=1885 and added it to the program button in TouchFlo, not the today screen. it seems to work fine if you press the button twice, better than 7 clicks. (My HD info in the signature, Telstra TouchFlo replaced by Standard HD)

If pushing the Play/Pause does not connect a previously paired BT Stereo Headset to your HD then it is not a true A2DP profile headset.
See if you can get your hands on a pair of folding Sony DR-BT22 headphones.
True A2DP with built in mike to answer incoming calls. Bass is very good and full funtion with the HD.
Highly recommended.

Agree
You guys are correct, the smaller headsets that try to share the Play/Answer/end button are probably the issue.
I have been using A2Dp Toggle 1.1 as mentioned and link above and it works great, no loss of sound noticed.
We should start an XDA (not just HTC) WiKi to list headsets that connect or not for WM5 and WM6.

HD Compatible Headphone
I have a Sony DR-BT50 headphone that works beautifully. The sound is brilliant for Music and particuarly movies that I have transferred from DVD to the HD with MP4HT4HD!
I never thought that i would watch a movie on a screen so small but the clarity is something else and the high audio signal with the bluetooth headphones make it a pleasure! Great for long layovers at airports etc.

Any in-ear types that work?
All the sets that I have seen posted as working are the full headphone (over ear) types, and this may again be a shared button thing.
Does anyone have / know of an in-ear / earbud type that works / connects correctly

A2DP Toggle 1.1
I dowmloade that A2DP Toggle 1.1 on my phone. I use HTC TYTN1 running Windows Mobile 6 Professional and this software gives hell to say the least.
When I connect it to my headset, it works fine BUT it does not pay MP3s on my headset. It keeps on saying ERR on the icon of the head speakers (the second icon form bluetooth icon). I even asked most of the technician but no one knows anythings. If anyone knows what my probles is, please rescue me!!!
I might be doing something, please help me guys

Toggle works for me!
I had the same problem, the triangle powers prog didn't work for me. In fact the headset icon was on but no playback.
The toggle 1.1 works, none of the funcitons described on it's website are available, setup and various icons are from the home page but HTC Touch HD home page doesn't support that.
Never the less, putting Toggle in my program list and using it toggles easy between phone speaker and headset. Like someone has already said, two clicks and we're in business from starting my van to getting music from my phone on the stereo. I'm happy enough with that.
I have a Pioneer stereo with Parat built in, so I get BT audio and Hands free calls. All seems to be working perfectly now. Thanks to this thread.

Music to my bluetooth earpiece

I've tried 2 apps and i have not been able to get them to work. I'm trying to get my music to play in my blue earpiece. I've tried Blue Audio and bluetunes and have not been able to get them to work... anyone else have any suggestions?
p.s
im not being cheap i have bluetooth headphones i just need a small earpiece to listen to music at work.

the quality is horrible from a BT headset or does that even matter...I have something on my computer that i'll post when I find it

The issue is not always because of the music player application.
Does your Bluetooth earpiece have A2DP support? If not, consider buying a new one that has, e.g., I listen through a Jabra BT8040 - no need to install any application to force an audio stream.

Forget it I think its one of the apps you tried

Well im using Jawbone 2.
Im not too concerned about quality because Im not going to have it on that loud.

how i get mine to work is,i go to comm manager then set up bluetooth device,go to settings then advanced settings (additional setup options),then go to audio and enable play system sounds on a remote hands free device and it should work. hope that helps

Here is what you need to send stereo bluetooth to a mono bluetooth headset. I use it and it works great. You might have to play around with it for a bit to figure out how to work it. Just run the exe on your device and not on the computer. One exe sends the audio and one exe stops the audio.

bt audio
damn beat me to it james yes bt audio does work but i use a jawbone 2 & i route it through advanced bt settings in comm mgr i used to use it on my wing but iv graduated to my monster tp2

No need for BT app
On my TP2, there is an option in the BT settings to route system audio to the headset...this automatically plays my mp3's through my BT headset, mono or stereo. has worked well on any of the builds I have tried without needing to install any additional files or change any complex system settings.

A2DP sound quality issue with Galaxy S 2

Hi guys
i read xda so much, but i don't write as well
i have a big issue with my galaxy s 2
i use a bt car stereo, with a2dp and avrcp support
i used to stream all my music collection from my iphone4
now i got my sgs2 and i love it... but
the audio stream looks "limited"
it seems a bandwidth issue, or i don't know a quality issue
with iphone4 i streamed at full quality, now the sgs2 sounds a lot worst
other than that, i have to disable wifi because if on, the music is choppy and skips a lot
with wifi off, the stream goes well, but it sound bad...
sorry for my not so perfect english... i hope there is a way to improve sound quality because i "live" with a2dp on in my car...

That's strange. My a2dp stream actually sound better from sgs2 than it does from my ipod touch 2nd gen, iphone or my computer (bluez).
Receiver is a belkin stereo a2dp receiver.
Are you sure that it's not in handsfree mode? Long press the a2dp device in bluetooth settings and there should be an option to select it to be a media device, make sure it's checked.

thanks for the reply gvoima, no it's in media device mode
i think the problem is the bitpool
i've got the same problem of this guy: http://forum.xda-developers.com/showthread.php?t=708685

I got a belkin stereo receiver as well, but it sounds bad and choppy, just like the topic starter described. Though still compressed (this is a known issue for A2DP due to bandwidth limitations) songs sounds much better from my Nokia E52 work phone.

The "but my (insert phone) worked better" isn't really valid. For as many people who make that statement there are an equal number who are shocked that the SGS2 works where other phones haven't. This is kind of like the Wi-Fi issue. When two pieces of equipment don't interact well you can't just blame one of them.
In my car and on my Yamaha YSP-4000 the SGS2's Bluetooth works better than any phone I've used. That includes the HD2, G2, and G2X. The sound is much more defined and headset controls (random and repeat) show available for the first time. The SGS2 also feeds track info to the car which none of the others did.
Bluetooth connections and sound quality are always a big YMMV.

My Sony MW600 sound great, I use to have a Motorola Defy , and it use to have an "Enhanced Stereo" option in the blue-tooth menu, the Samsung S2 does not have this option.

@BarryH,
Oh I know, I not blaming the SGS2. I only think the SGS2 out sound to it's output module which is somehow less suitable for the kind of compression, maybe set by the Belkin module. Actually I'm currious if there would be ways to change the way the SGS2 sends sound signals via A2DP

LG's implementation of Bluetooth drove G2X owners crazy. Check out this thread from the G2X forum...
http://forum.xda-developers.com/showthread.php?t=1117769
Maybe it will help. The only other solution for the G2X was installing an AOSP ROM.

Well, I tried it (Bluetooth Fix Repair), but off-course that tool is for a problem the SGS2 does not have.
From the tinkering I've done now I know.
- Having MusicFX installed does not make a difference
- Video players running ffmpeg codec do also not make much difference in sound quality
- The -type- of file does make a difference, i.e. low bitrate files play better
This makes me think, is there a music program which can resample/recode music before playing. I'd rather have software do that than A2DP do it badly, or is mono output (other than all the tools enabling playback on mono headsets which is for pre-A2DP headsets and thus something else) possible?

Edit /system/etc/bluetooth/audio.conf
Uncomment "Master" option and set it to "True".
Uncomment "MaxConnections" and set it to 3.
Most Android devices have this file configured poorly by default, those 2 settings should help though.
I'd suggest also enabling HFP and AutoConnect.

Great! That definitly reduced creaking/noises and even the occasional stuttering music!
Since you seem to know your stuff, would there be a way to send a mono signal to (only) the A2DP stack and would this decrease the 'tin can' effect? I'd rather have better upper tones than stereo.

Thanks for the suggestions...going to try this and see if the sound quality improves in my car stereo.
Till now the best A2dp sound quality was on my Nexus S, but that was with the help of custom rom development and vodoo sound. Worst was the g2x.
Sent from my GT-I9100 using XDA Premium App

Ok guys, I think I might have... accidentily... run into a phenonemon.
I tested my phone on a Creative D100 wireless speaker it it went great, no tin can sound, no hickups.
This proved to me that there had to be something wrong. Now when I was posting here earlier I was listening a lot to music and at a certain moment I thought... wait I'm not hearing a tin-can sound anymore. However, later on while testing I heard it again so I thought I imagined it.
Powering off the phone and powering on again I was able to create this again. No tin can sound... however a lot of hickups (as if a lot of data had to be sent and it didn't quite fit). I made a call to my work phone (sound on the handset) to test and then the tin can sound was there again, no hick ups anymore though. Strangely enough a haven't been able to replicate the 'no tin can sound but hickup situation' though by powering off and on again. Tried after playing on the Belkin on the D100 again and no problems at all, great sound and no hickups whatsoever.

It appears to be a bigger issue with android connected to the bitpool setting the bluetooth receiver desires...
http://forum.xda-developers.com/showthread.php?p=14944891#post14944891

Let's hope the upcoming Cynogen can fix this issue.

I too felt that the A2DP sound quality on the Nokia BH103 is crap as compared to my Nokia 5800 (sounded even better than stock wired headset). It also uses a lot more battery, I find mediaserver using a lot of battery.
How do we escalate this to Samsung?
