Poor BT Stereo (A2DP) quality?

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?

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...?
??? :arrow:

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.

Why is A2DP so f'ed up?

Dont get me wrong, I'm loving the fact that we have A2DP when we shouldn't (thanks Microsoft :twisted: ) but I've read and reread every single thread about A2DP on the Prophet and I still can't get it to work the way it should.
Here's what i have: a Qtek S200 updated to the latest WWE Dopod ROM, with A2DP patch installed, and paired to a Bluetake I-Phono Mini (BT450Rx). I get both handsfree and stereo profiles as an option, and both work to a certain degree.
But here's the catch: I tried all the music players out there, and none even approaches a decent level of use:
- Media Player 10: best so far, but the Play/Pause button isnt working (only FF/REW), and when a call comes through, it answers on the headset, but when I hang up, the music resumes from the speaker of the Prophet and not the headset.
- Pocket Music: very buggy, skips a lot, and the AVRCP controls dont work.
- TCPMP: sound is fine, porbably the best, but once again, the controls for playback dont work.
Am I doing everything wrong, or is there really no way to get at least one of these to work?
Any thoughts/remarks/info etc would be appreciated.
thnaks, TDX

yeah, A2DP is a deal breaker for me, so I'm waiting waiting at this stage...(have yet to buy prophet)

So, no one has found a software combination that actually works?

After the call, the music will only resume at the begining of a track.
Therefore, hit your rewind or forward button to resume music.
Even with this, it's still not seamless.

Well, I have an S200 with the A2DP patch working in conjunction with my Plantronics Pulsar 590 Stereo headset and I'm really impressed with its performance. Hi-fi sound under WMP10 and PocketMusic. No skips even without overclocking. Flawless Calls in the middle of my music. Resumes perfectly.
Must be a problem with your headset brand.
Never been so happy with my PDA/Phone.
Best regards...

I don't think so.
I have the same problems with a Motorola Ht820.
If only some of us have this problem, we probably didn't install the fix properly.

What would be really cool, would be if someone could detail the exact steps needed to install A2Dp on the Prophet, enable AVRCP and get everything to work nicely. I know there have been other threads regarding this, but it's been a while since the patch came out, various people have posted different versions of it, new ROMs came out, so it all gets a little confusing.

It's really simple. I just used the attached file that I found over at i-phone forums. Read the simple instructions.

Ah. That's the registry edit method.
I installed mine the simpler way. Maybe the simpler way is not complete.

Thanks for the responses everyone. I actually spent some time and did some extra research/testing. Here's what I've narrowed it down to:
What works:
1. The A2DP works, as far as pairing, handsfree and wireless stereo go.
2. The AVCRP sort of works (only in WMP, othesr software apparently don't support it yet).
What doesn't work:
1. Play/Pause button in WMP. For some reason, FF/REW work, but not Play/Pause.
2. When I answer a phonecall with the BT450 while listening to music, it pauses the music, but when i hang up, the music reverts to the speakerphone (it loses the wireless audio status and i have to pair it again manually).
3. Finally, and I dont know if this is a bug or not, when I turn on the headset, it automatically establishes a wireless handsfree pairing, but not a wireless stereo (music) pairing. I have to go into settings and pair it manually EVERYTIME I want to listen to music. This sucks.
So, anyone else having the same three problems as me? Anyone has solutions to these.
I would be most eternally grateful.

Nope... It's not a manual regedit per se, it's all included on a .cab for easy application and a few other files to put in the Windows directory.
At least for me, it worked flawlessly while paired to my Plantronics gear.

You gotta be joking about HI-FI performance. I have the same headset and when it sounds really good with my ASUS W5A laptop with Toshiba BT stack it doesn't work all that well with Jamin. It sounds like it set to low quality mode. A2DP on Prophet that is.

Nope ID64, no jokes... It really is working for me perfectly even without overclocking.
Have you tried PocketMusic, because Media Player 10 sucks big time in all respects on the Prophet...
Are you sure you are pairing as Wireless Stereo profile? The first time I tried it, I mistakenly selected Hands-free profile and sounded just as you described.
ROM Version: 2.9.7.24 WWE
ROM Date: 2/9/06
Radio: 413.1.03
ExtROM: 2.9.7.106
A2DP Applied

Does PocketMusic have AVRCP controls though?

Not sure if it's implemented inside PocketMusic or in the A2DP profile itself but AVRCP do work in PocketMusic without a hitch. The Plantronics Stereo Headset controls work prerfectly, and the PocketMusic fade-out-fade-in feature sounds simply impresive!

BT Headset works for calls but not music??

I have a 8125 with a Nokia BH-600 bt headset. It works great when talking on the phone but I really want to listen to music too...
Is it possible to play music through the Nokia BT headset?
I have Media Player, Sound Recorder, and the CORE movie player but none of them play sound through the Nokia BH-600 headset! I also have a Moto H700 if that makes a difference.
Thanks!

I am not an expert on this topic so someone can correct me if im wrong, but you cannot play music through your bluetooth headset unless the headset is A2DP compatible. You also need the A2DP hack that can be found here:
http://forum.xda-developers.com/showthread.php?t=263735&page=7
Anyway, to get an A2DP headset, look on eBay; you can normally find them for around 60-80 shipped, for a quality one. The hack is a cab file that just needs to be installed before pairing the headset.
Hope that helps.

Being dumb here... how does this hack work?

I posted the link in my above post. Basically, just download the hack, copy it over to you phone, and click on it using file explorer and it will install. I am pretty sure it just adds to registry tweaks and DLL certificates, but I am not 100% sure. All i know is that is works great! After the install and a soft reset, when you pair a A2DP headet, it will have the option for setting as wireless stereo. Take a look at the thread above for more information.

Ah, so then any audio that that gets produced on the phone gets streamed on to the BT headset?
Sounds promising. I was wondering if there was a way to get navigation commands to go through my car BT kit.

I also wanted to be able to do that, as I have a bluetooth speakerphone in my car. I do no think this is possible with just a regular bluetooth headset or speakerphone.
However, I do think if you have an A2DP headset the navigation sound will come through. I am not sure if your car kit is a speaker phone or a headset, but if you prefer a speakerphone in the car (as I do), I highly doubt it's possible, because I dont think anyway speakerphone is A2DP enabled. Nevertheless, people on this forum have done more amazing things so search around, you may find something.
And yes you are correct, after the pairing, any audio that gets produced by your phone will come via the headset (hence my thinking for navigation working with A2DP headsets)

Hmm, i have got a parrot ck3000. Not sure if it is A2DP compatible. Is this hack/cab file uninstallable? lol, im asking so many questions! I think i might just give it a try.

Heres a question (as these forums are a mess and i can never find anything), Is A2DP included in any of the latest roms? I am running the AKU2 rom that t-mobile last released, so i assume that some of the cooked roms are miles better.

your options
There are 2 ways to approach this issue:
1.) A2DP hack or updated ROM (for the best possible sound quality) needs an A2DP compatible headset/headphones or home BT transceiver.
2.) Mono BT hack for BT headset (you lose Voice Dial) has the lesser sound quality of the mono audio channel (the one you hear when on a phone call) See this tutorial for more details and options.
I highly recommend any and all BlueTooth articles by Menneisyys one of our Moderators.
See his articles on BlueTooth and more here.

Awsome! Thanks for the link to that article. I will give the BTAudioNav a try to see if this works how i want it to! Coolio! Thanks

Ah balls it. It looks like its just another constant streaming program. Shame, i would have loved to just get the commands to be said and then the radio wont be contantly cut out.

my 2cents
Just installed this .cab on my wizard (o2 xda mini s, G3 un-updated at all.)
Works a treat, I'd foolishly bought a a2dp headset without checking compatibility and now it is compatable.

H.T.C Audio Booster on this thread added for the athena :D

hello after months of looking hard for the htc audio booster and pestering others in this forum i finally found the htc audio booster that actually works perfect on the htc athena and guess what its also in vga mode
below you will find 2 picture images of what it looks like and also the .cab file
the following things i noticed when using it is this ,,,when u pair a stereo bluetooth headset it doesnt work ,,,it only works when you use wired headphones either thru the 3.5mm or the mini usb port !
apart from that its all fine just wished they made it 10band eq would of been more serious for music listeners
please enjoy

Try TCPMP. There is equalizer which works with bluetooth stereo as well.

Audio levels on Atom

Hi gang,
I have been a long time Atom user. One thing that has constantly bugged me is the audio level - both in the earpiece and on Bluetooth connection to my car. Recently the IT manager at my work threw me a HTC Touch Dual (Nike) to evaluate for him. The audio (sound) level on both the earpiece and the same Bluetooth connection for the Nike is 100% better. Is there a ROM available that addresses the poor sound on the Atom or is it a restriction based on the hardware ?
I have tried a stack of searches however can't find anything that addresses this specifically ???
Phil...

OK.
Does anyone know of any registry hacks that help with $hitty audio levels for the Atom ???
After may searches there are heaps of people complaining about audio levels - not may solutions though.
Pleaseeeeee help the IT manager will be asking for the Nike back soon....

have you try SRS WOW HD plugin? it will amplify the audio
plus if u still think its soft, use the equalizer to amplify further.

Thanks Tabbe,
Two things looks like I need to upgrade the ROM to WM6.x to use SRS is that right ???
I may not have been clear enough - mainly concerned with audio levels for the phone - first in the earpiece and second for the built in speakers. Will SRS assist for these ???
Phil...
