I was wondering if any of you who has access to this device tried to see if it also suffers from high pitched noise like other devices when used with A2DP devices?
Is this using the sandard WM bluetooth stack or have they used an improved one?
Thanks
the Bitpool could be set as high as possible, dont know why MS set the default at very low since many devices support high data streaming.
without tweaking program, average people would think bluetooth quality is poor on this device.
Lurking around for years, I would expect anyone to search and apply suggested fixes in this forum before coming to a conclusion and askind this question.
Actually, I have applied most of those settings in both polaris and diamond. Even yough it is reduced, you still notice the noise during silence. Especially id device volume is lower and receiver volume is higher. This wasn't the case in n95 and SE m600.
Similarly in Vista with built in bluetooth stack there is some noise. Using a different stack such as Widcomm produced totally different results with same receiver.
if it was good in the m600... sony ericsson...
but it's made by HTC so????
Hi all !
I'm looking around for ways to better my audio experiences in A2DP with my HTC Touch Diamond. I keep hearing these high pitched metallic noises, and based on your posts, it could be an issue with Bluetooth stack. Is it the same with Xperia ? I mean, does A2DP sucks ?
These noises are a nightmare... I am using Diamond Tweak for my Diamond, any setting ideas ? Didn't try anythng so far...
Thanks a lot !

I use a no brand Stereo BT headset on the Atom and found the quality is unacceptable poor. I just want to confirm if it's just me or it's a common problem for Atom.
I found the BT stereo quality very poor too. Tried
1. i-Tech S35
2. Gobalsat BT-830 (apart from stop/pause, AVRCP works fine with WM 10)
3. Nokia HS-12W (apart from stop/pause, AVRCP works fine with WM 10)
quality is way worser compared with the original headphone that came with Atom. I read somewhere this was due to the poor audio chipset used in Atom. Any way to fix that?
BTW, all the above 3 Bluetooth stereo headsets have excellent audio output when listening music from PC (using Widcomm 4.0.1.2800).
I believe it was due to the BT version used. I too tried
1. i-Tech R35 (V1.2)
2. Nokia HS-12W (V2.0)
When pairing both of them with Atom, the sound quality is not that good (always got hissing sound). The same applies when I use the i-Tech headset with my 818pro.
On the other hand, when I use the Nokia headset with 818pro (A2DP enabled), the quality becomes quite good (no significant difference from wired headsets). BTW, I think the Moto BT headset supports V2.0 too, and seems ppl around got some good experience with it and 818pro.
As I mainly use my Atom nowadays (my 818pro got the screen misalignment problem unfortunately), I already forgot about BT headsets.
From all you guys comments, I am not alone in having poor A2DP quality. It's a shame for giving out A2DP but unacceptable quality. :evil:
I-tech S35
Thanks so much for that information. I was really tempted to "upgrade" to an Atom from my Mini because the former had the built in bluetooth so it's a good thing to know I shouldn't upgrade because I was really after the A2DP functionality (since I thought the full release a2dp would be much better than the mini's "hacked" a2dp).
Maybe the stack used on the Atom is not that good. Have you tried upgrading the ROM?
[email protected]
what are u guys sayin ?
the quality of A2DP in my Atom (last ROM upgrade) is excellent !
and i do know how to appreciate the quality, cause i came from a V3x (quality was amazing too).
i am using the motorola HT-820.
the sound is much better than my crappy ipod video (to sell if someone interested) :arrow:
to fix ur problems, u should :
1- upgrade to the latest rom.
2- turn the crappy equalizer off (its a really useless feature)
3- when u go to bluetooth settings, hold ur bluetooth device and '' set as wireless stereo''
that may be the key for clearer sound.
also i didnt like the equalizer (am i alone ?) i found that the speakers are worse than ever.
what do u guys think? :arrow:

How's it compared with the using the original headset came with your Atom? For me, bluetooth A2DP is way worse.
I used the same i-Tech clip S35 on XDA 2i, and the A2DP qualitiy is as good as the wired headset came with XDA 2i.
Thanks.
Wired vs Wireless
ok, with the regular wired stereo headset the sound is Ok, but not that good if i compare to my ipod video.
i highly prefer the a2dp system as it seems ur inside a nightclub while using it.
but if i have to choose between the wired headsets or the HT820, i would rather go with the BT headset.
the only thing, is that dangerous for life ? (like getting brain cancer etc... wish not..)
As I mentioned before, I have tested all the combinations for 818pro, Atom (both with latest rom) and two BT headsets i-Tech R35 and Nokia HS-12W, and only found that the BT 2.0 combination, ie, 818pro with HS-12W, produces good enough music quality. For all other combinations, there is always some pretty obvious hizzing sound around when playing a soung. That hizzing sound is not background sound, as it won't appear if I stop playing any song. It only appears when a certain part of a song is played.
It seems to me that the hizzing sound is caused by insufficient bandwidth or over-compression of the data transmission (or both?). This also matches with my test result.
If I am using the 818pro (it is pending for repair), I will surely bring the HS-12W around. Otherwise, I will just stick with my wired adapter + Sony headset.
possible sol guys.
what is that ?
'' MSFP AKU 2.0 ''
it looks like a guy in another forum did an upgrade with this and got a superior sound etc...?

AKU 2.0 comes with support for A2DP.
In the case for XDA Atom, A2DP was supported on the day O2 released Atom.
A2DP quality in Atom was poor regardless of the Rom version, I tried the following roms:
1. 20060123B1WWE
2. Xda-Atom-ENG-20060123_Feb2006_.exe
3. R060221N_MN1ARC_RS00045
4. DSUU_ARC_C060414WWE_R060327N_EX0016__test_only_not_for_sale
5. Xda-Atom-ENG-20060426B1WWE
As described by buruburu, hizzing sound appears when a certain part of a song is played. Turning On/Off the equalizer doesn't seem to have any effect.
When listening the same song using wired headset, the quality was good, so can't be the problem of the song I am listening.
When listening the same Song using my PC (BT 1.2 with Widcomm 4.0.1.2800 stack), the quality was good as well.
So, no problem with the song I am listening, no problem with the BT Stereo headset I am using, no problem with the BT version (1.2 in Atom, 1.2 in PC; don't have BT 2.0, so can't tell) I am using, and my BT headset works fine making/receiving phone calls.
Conclusion:
1. the BT stack in Atom has a problem;
2. the audio chipset in Atom was a cheap and lousy one;
3. my Atom has a problem (I am in UK, don't have another Atom to test)
If it's (1), hope someone can fix it!!![/i]
tcmp
forgot to tell u guys : i get good quality cause i dont use crappy windows media player to play my mp3s, i use TCMP for every file i have.
and it works a charm.
the only thing i dont get, is that sometimes during the song play, it stops for a second then go back to it.
wierd :shock:

Aha! Finally found this topic. I'm on O² Atom + Jabra BT620s. The headset sound quality is superb stable on pc (5mb limit Bluesoil). On Atom... WM10 sounds too low even volume maxed, the equalizer doesn't work on A2DP. The best is on TCPMP where I can blast the pre-amp to make it louder. The quality is "ok²", hisses are seldom but hiccups exists once or twice in wma/mp3 tracks and too bad headset playback function only work on WM10 not TCPMP. And to click my headset when answering calls, I've to set TCPMP not to play on background, after clicking, I've to increase the headset volume.
Does any of you guys who's using other than Atom experience hiccups on A2DP? And those with Atom other than goldsaint? I don't think it's Jabra's but Atom fault itself. I've only SmallMenuPlus and O²Plus running in background (all startup removed), no battery/space monitors on today and overclocked to constant stable 520Mhz with XCPUScalar on the latest firmware. Thank you...
Am using I-Tech Clip S with my ATOM and sound quality is EXcellent!!! No hissing sound at all.
I highly recommend taking a look at the following,
http://forum.xda-developers.com/viewtopic.php?t=54621
I had the same complaint, but these registry edits cleared up my quality problems almost entirely.
Tweaked the bitpool settings to 53 but did not recognize any improvement. The other 2 tweaks is useless for me-- whenever i used my I-Tech Clip S BT headset/wireless stereo, can't hear the other callers voice. Streaming audio to my Clip-S is OK but no noticeable difference.
Cheers
I've tried my two bluetooth stereo headset on HP-2210 , DOPOD 818Pro and O2 Atom,one thing is certain,the sound qulilaty in O2 Atom is worst and poor.I consider the problem is ROM Firmware.
Some of the tweaks cause more harm than good
I removed all traces of these tweaks by doing a hard-reset, and my bt stereo is just fine with the occassional break. 8)
IMHO we should not just apply every tweak just because someone posted :twisted: EG some one claims he installed Atom Exec ROM on regular Atom Now he has vamoosed when asked to share. Some one posted a 4-letter word due to the mess he had when he followed that line :twisted:
Not to go against the current trend, but I entered the following into the reg editor and it made a huge improved in the sound quality using the Samsung SBH-100 headphones.
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Bluetooth\A2DP\Settings]
"BitPool"=dword:00000053
"SampleRate"=dword:00044100
Still get the occasional skip but fingers crossed something will come up to fix this soon.
I got my X01HT recently and found the quality of MP3 playback via Bluetooth really suck! I got very noisy sound, like "sisisi" sounds all the way! Besides, the call quality is also poor as well.
I tried with many different brand of bluetooth handfree, but all got bad quality with X01HT, but not with other mobile phones with A2DP.
Why Hermes got this serious bug? Is there any update to fix this suck bug? Cannot imagine why HTC releases Hermes before fixing!!
Please please help!
1, welcome to XDA-Dev
2, you may want to read / follow my articles. I've published a LOT of info on this subject (see for example http://forum.xda-developers.com/showthread.php?t=282017 ). In a nutshell, all you can do is installing the Widcomm BT stack.
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.

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.
http://www.theunwired.net/?itemid=3311
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.

Same here ....
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...
low volume on p3600i

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.
I've searched here for hours and haven't found a fix for this. Unlike many of the posts I've found and read here, I don't have any issues with skipping with my bluetooth earbuds.
On my 8525 with 53 decimal set for bitpool and max bitpool and jointstereo=0 I get tinny hissing artifacts. not worth using.
these are no-name earbuds similar to the itech clip ones. don't know who made em-came from ebay. they worked great with my widcomm stack harrier.
increasing the bitpool numbers further has no effect on these. they don't seem to skip at all though. am I missing another reg setting change?
are there off the shelf headphones that don't skip without the a2dpfix service and work well with hermes? I see mixed answers on many of them.
just when I think this phone is pretty stable it locked up this morning and didn't alarm. I overslept...
I'm also having same annoying hiss issue, afaik only another bt stack (namely widcomm) or maybe new aku update would solve this problem.
don't know where they are going with porting widcomm to hermes,
but hope they have some progress...

Hacks, registry tweaks section of Wiki, search "A2DP" or "stereo". I use sony-ericsson hbh-ds970's and after the tweak, sound as good as my old wired earbuds. Only shortcoming is the occasional sound drop (millisecond or two, but still annoying). Setting PocketPlayer priority to "normal" virtually eliminates the problem. An extreme solution is applying Sleuth's A2DP fix... search the wiki for more details.

You mean skipping issue rather than hissing sound issue ?
-Kha
The hiss is a known artifact of the M$ BT stack. My testing with the Widcomm stack eliminated this issue. However, out of the box version 1 Widcomm tests showed decreased fidelity and noticable buzzing on the high end. However, I believe there's a number of A2DP fidelity tweaks that can be applied to correct this. I will start working on this when superdave gets the handsfree issue solved .
I just bought a HTC S100 BT Stereo Headset. It works OK, but only with joint stereo active. If I set the UseJointStereo to 0 (Registry Settings) the sound is just awful!
And yes, I tried alls the different settings for better audio quality - that does not make a change at all.
Is this problem known? Any remedy?
A
Problem known and due to the poor M$ stack...
Only solution for decent BT stereo is the Widcomm stack (see the wiki)
It is painful to use (need to reset to avoid out of memory message), but the sound is great and it works along the M$ BT stack (not at the same time so...)
there are a few bt headsets that work well. my nokia hs_12w works well, but it was pricey. bulky too. my older no-name one had a terrible hiss, but this nokia doesn't.

I need help with this also.
I installed the A2DPfix and the skipping is now gone but the quality is still very poor. There seems to be a lot of static noise or something. I applied the HTC Tweak A2DP fix for quality but it didin't do anything and now I can't get rid of it.
Please help.
