Hi,
maybe someone can give me some info.
Have a T-Mobile Germany MDA Pro with the newest Stock ROM supporting A2DP.
Have board a brand new Plantronics Pulsar 590A Headset. It works, but the quality of the sound is very very bad with my Universal. I have also tryed the smal A2DP Sender, that comes packed with the Plantronics device and the quality is 100 times better. What is the problem? Can I adjust the bitrate of A2DP transfer in wm 5.0 registry?
The sound is a little much deep and on mid to hig frequencies, i hear a high frequencie noise.
Does anyone else has this problem?
This is not a problem of the receiving device.
Thanks for any help on this :`)
No Ideas?
Please Help!
I have the Qtek WWE ROM on my Qtek (latest official version). I use a Jabra bt620s, and i have no problems with it.
Maybe it's some obstruction of the signal? Do you encounter the problem when the Qtek is in clear view of the headset at a meter away?
I have the Motorola HT820, and finally got round to installing the Qtek WWE ROM today. Connects fine, I can walk into another room from the Uni and have no problems; But -
I also get a high pitched noise, particularly on music with lots of treble. It can be controlled up to a point by tweaking the graphic equaliser, but it is still annoying.
When using the HT820s linked to my Bluetooth PC and laptop, they sound superb - so it is a problem with the universal.
Thanks so far, i start hating my Universal ....
I think, there can be 3 reasons for that.
The Windows Mobile A2DP Software encoder, if it is software encoded.
The Bluetooth Chip, if it is HW encoded in Bluetooth.
The Radio ROM or Chip, if it is encoded on the Radio Processor.
I am not so deep in the Universal Technologie, but i know, that the sound was very clear on Blue Angel using the broadcom stack. So I think, it is M$ Bluetooth that makes the problem, but i am not realy sure.
... or is there anyone how don't has this kind of problem?
Hi,
I personally have never had that problem (which I interperate as "some form of noise" when listening to music over A2DP) you guys mention here, neither with my Motorola HT820's or i-Tech BluePRO's.
Only problems I have had with A2DP and my Universal is;
1. Pause/Resume button not working always in Windows Media Player (works fine in latest version of PocketMusic though)
2. Not automatic reconnect of A2DP when I turn headset on (only prob with the i-Tech's, Motorola's seems to work fine)
3. Occational drop/loss of sound for a second or two (have this under control now, only an issue for me now, when there is to much obstructions between Universal and my i-Tech headset)

This is a general Universal Problem. Maybe Radio Interference, maybe missing some CPU power.
The noisy and unclean sound can be a ROM Version Problem, if you don't have that. I have tryed also with a Linux Computer as A2DP SINK Client, and the sound is same bad.
That's my ROM Version Info:
ROM-Version: 1.30.113 GER
Radio-Version: 1.10.03
Protokoll-Version: 42.44.P8
ExtROM-Version: 1.30.223 GER
Windows Version is 5.1.195 (Build 14847.2.0.0)

Try downloading the latest PocketMusic version (if free for 30 days I think...so you'll be in heaven for 30 days at least), there it works perfect. ...it was enough for me to "cough up" the money to buy it!
And yes it seems to be every second time, and then one has to press button on Universal/Media Player once...bloody irritating...when the Universal is in the bag or something.

Yepp, I have exactly same behaviour (handsfree no prob, while A2DP needs manual reconnect with iTech's...but with the Motorola HT820's I belive it was automatic though)

For me I am pretty sure it is pure radio problem now (have tested with an app called SuperTask, and A2DP takes approx 20% CPU, and my JasJar now used a total of 40-45% CPU when I listen to music over A2DP with PocketMusic). I only have this problem when I have the JasJar in my pant pockets, are in an area I know there is a lot of interference+have some obstructions. Except from that it is fine now.
You can see this post on my "socalled test" (it was just a simple test, but it seems to give a good indication at least) of A2DP's effect on CPU here;

I have no clue...do you have a Universal (I would guess so from that you post it here )...if so the HW is identical...so then...yes it should be the SW/ROM...since you actually have tried with another "headset" (your Linux computer). But I am sorry, that I am not much of contribution...if nothing else...I agree with your logic here!
BTW my ROM version++ is stated in the A2DP-test post I linked to above (don't remember the numbers...but I have the "latest QTEK WWE" ROM).
Thanks for your comments.
Maybe it's the T-Mobile Germany ROM that is the Problem. Have allready called the technical support at T-Mobile, to help.
Maybe they are ignoring me, but i have tryed.
Universal's blue tooth signal terrible
Look I had many imate devices and bluetooth sets. The Universal has a very weak bluetooth signal even with normal bluetooths.
I have tried 3 or 4 different bluetooth headsets and they all give me a max of 3 meters. With the Jam and pda2k with the same headsets I used to get 10meters.
I gues this is the reall problem you are facing, the bluetooth reception is terrible on Universal, try being really close like 40CM away and if the sound is good you will know that it is only a reception issue from the universal.
I noted the 40 ~50 cm distance problem when I reviewed my nokia hs-12w a2dp headset about a month ago, it is very irritating. I think it is to do with where the BT chip is placed !!! it is between the keyboard and the battery, from what I could tell of the exploded diagram on this site !! meaning it is surrounded by metal !!! not good .
PS I never have problems connecting my hs12w headset for audio use, however if I take a phone call, after the call has ended I loose AVRCP

Hi cr2,
yes I read about it in IRC Log. But what you like to do is, streaming sound direct to the bluetooth hardware. Universal hardware supports this feature. There are 2 Bluetooth Profiles implemented for, one is called "Handsfree" and one is calles "Headset" and ini Windows Mobile Registry you will find it if you look for "Audio Gateway". The registry values are also documented in the online MSDN Lib. I will post a link, later, if I find it.
What I am doing is A2DP, that means ... all stereo sound will be compressed in software and then send as datastream to the bluetooth device.
Have attached the A2DP specification. Under Linux there is a project calles "bluetooth-alsa", that supports A2DP and Handsfree. Look for it at sourceforge.net.

There are several options here. It can be sent directly
on some phones, or (theoretically) through the phone,
or even redigitized from the analog (for mono).

Hello.
I bought a stereo headset from Qstarz "BH-Q395S".
Using no tweaks.. Quality is low. Like low bit rate.
Using the fit4cat tweaker , sound sounds as it is higher quality BUT it is distorted in the high`s.
Is this the normal problem everyone is having ?
What can I do ?
Does ROM updates help this issue ?
Do you think the HTC headset will be better (s100)?
BTW. When paired with my PC , sound is great.

The A2DP support in pre-AKU3 MS BT stack sucks and this can't really be helped. AKU3 is said to have eliminated this problem.

I don't think so. It might be better (as are some - few! - models, for example, the Jabra), but I wouldn't hold my breath for it.
So there is hope for the future..
The question is when and if will "AKU3" be avilable for the tytn ?
Can the MS BT stack be changed?

1, the release date of the TyTN AKu3 ROM (if any) is unknown
2, the A2DP quality issues of the pre-AKU3 ROM can't be fixed (unless someone extracts the related DLL files from an AKU3 ROM in a way that is compatible with previous ROM's).
The only way to avoid the quality issues is going staright for the Jabra headsets (or going for another PDA with the Widcomm BT stack - or any Palm OS device, for that matter). See my discussions of this issue over at PPCT and HowardForums.

Or manage to hack the Widcomm stack to make it work on the TyTn like it was done for the axims.. i seriously make a donation if someone would make that happen. Heck, i'd even purchase it if Broadcom was willing to sell it..

Post a "donation thread" ("let's collect, say, 500 bucks and give to the first hacker that manages to do it") to "Dev and Hacking" here as was done on AzximSite, it may speed up hacking / developing

The HowardForums folks say the pre-AKu3 MS BT A2DP works flawlessly with the Jabra 620, unlike with the 590A and some other models.
I have a Jabra 620 and I'm not that impressed. The only headset I have had which worked completely flawlessly was an Itech S35 (but no AVRCP unfortunately).
I'm currently using a Nokia HS-12W which only hiccups if the Hermes is busy doing other things (but I've had to set the bitpool value to 48 decimal to achieve that).
All in all, I can't wait to see what happens when AKU3 arrives! Just as long as they don't break more than they fix ;-)

We all know that this BT stereo implimentation sucks! Main problem is that EDR is not implemented correctly (note bumph on this phone does not show it as others do!) BUT!! if you have tried to use ANY A2DP enhancement CABs then make sure you have usejointstereo set to 0 and pick up an iTech clip S35 (as they work OK without EDR) to use with any decent headphones and you will be fine...

The sound quality on the 620 is reasonable and it doesn't actually skip too badly, but I find that the RF performance is sadly lacking - if I use it anywhere where there's any other wireless signals around, it keeps giving periods of silence. For example, if I try to use it when shopping in the nearest supermarket to my office, from the moment I go into the store, I can only get odd bursts of music - about 1 second for every 5 seconds of silence. When I leave the store, it reverts to working reasonably again. This isn't just with my Hermes, it used to do exactly the same when using it with my Wizard as well.
The Itech S35 is the only A2DP device that has ever worked perfectly with my Hermes (with the bitpool set to decimal 58) without any skipping. Unfortunately, I really wanted AVRCP, so I've just bought a Nokia HS-12W and I'll see how that performs. So far I've had to set the bitpool down to decimal 30 to eliminate skipping, but I can live with that.

Let me disagree. EDR has little to do with this stuff as you do NOT need EDR to transfer stuff at 256 or 320 kbps. It certainly good to have but is not a requirement for A2DP. This is why, for example, BT 1.1/1.2/2.0-without-EDR-only Widcomm or Palm OS devices have no problems with the sound quality (ever tried to listen to a, say, year 2003 Tunfgsten T3 to A2DP? It is flawless.) - unlike with the MS BT stack.
I'd say this is ONLY an algorithmic problem in the A2DP encoder in the MS BT stack. (I've pretty much gone into details on the matter in my articles and over at PPCT and HowardForums. The problem can not be fixed by any recently known hacks.)

Haven't you encountered the "when there's any kind of singing, there's an awful lot of distortion" symptom with this headset?

Yes, there is some distortion but I found it bearable if I was using a decent pair of headphones plugged into the S35.
I should point out that I'm no audiophile!
OK I see that some of you already got the device. My wife wants to replace her Nokia N80 for the white version. Now I previously had an Orange SPV M3100 (HTC Hermes) & had no end of problems with that sold it & now happily using an Asus P525. So how about the the Trinity.
-Is it stable?
-Does A2DP & AVCRP work properly as in having proper stereo output?
-Does the A2DP reconnect automatically to WMP after receiving a call (the -Hermes never did, had to restart everything).
-How's wifi reception (the Hermes was crap). She uses wifi a lot as we have 250mins free BTOpenzone minutes a month.
-I looked at the HTC website but it seems they do not supply firmware upgrade support for their devices. So where can you get them officially?
Fill me in guys. Thanks
Is it stable?
I don't feel it's very stable when coming to the phone part. If I've used the device for a while, I often have to hard-reboot it for the phone part to work again(it just stands "calling", and nothing happends)
-How's wifi reception (the Hermes was crap). She uses wifi a lot as we have 250mins free BTOpenzone minutes a month.
The WiFI reception on my phone is very good. I've actually managed to connect to hot-spots which my laptop didn't manage to connect... *me like*
-I looked at the HTC website but it seems they do not supply firmware upgrade support for their devices. So where can you get them officially?
In Norway you get the official firmware updates/rom from the local distributor.(Dangaard and Brightpoint)
What about other features, like those related to the cameras?
How is visiophony with the front camera?
How is the picture quality of the back camera? Most of the reviews are made with good light conditions. What about the pictures in low light condition?
Movies? Are they correct?
Battery life with that 400 MHz processor compared to Prophet?
Could anyone post pictures/movies made with Trinity?
The wifes P3600 arrived this morning. Been playing with it all for a while & here's my 1st impressions.
Good
Looks nice & shiny
Small size
Excellent loud clear external speaker
Nice & responsive
Phone reception & general operation is fine
3G works well
Bad
Shiny surface = fingerprint magnet
MS bluetooth stack, better than before but still lacking
A2DP implementation. Not real stereo, only mono out from each channel
Also when disconnectd from WMP it doesn't auto reconnect.
In summary if you used previous HTC devices before then you'll be familiar with this one. When used as a pda & phone it does most things as expected, the menus & general operation are same as before.
But its going back, one of the main reasons being the crap A2DP. Wifey uses music player a lot on her 1 hour daily commute & the fact that sound quality is rubbish (low volume & no stereo) & no option to connect a wired headphones as theres no headphone jack. The same problem as the Hermes in that once disconnected from WMP it doesn't auto reconnect. Have to go into Bluetooth manger to re establish the connection.
Also comparing it to my Asus P525 other than the smaller size, 3G, louder external speaker & looks a bit nicer, in all other depts the Asus is as good & some areas much much better.
Well, my opinion is that the camera sucks... Was on a party this weekend _with_ good lighting, all the picutures came out blurry *argh* (could be it was too much light tough?...)
The videotelephony-part on the other hands is quite good(for videotelephone, NOT for taking still-pictures).
And I also don't like the 2-7 sec. delay when you try to call someone... *argh*

Yes, proper stereo could be possible with a registry hack but how many end users are to know that? Only the hardcore users frequent forums such as this & get to learn a lot about their devices. Assuming it can be done then why didn't HTC enable it in the first place? Mention a registry hack to the vast majority of users out there & I'm pretty sure you'll be met with a lot of blank expressions & ??????
With the aesthetic design of the trinity I think HTC are trying to market it to more mainstream audience, thats why my wife likes the look of it, but in all honesty how many of these new users will know how to exploit the device to the full. My wife never visits these forums & even her 8 month old Nokia N80 is still out of the box stock.

I thought the registry hack was only to enable A2DP on those devices where the manufacturer had disabled it and the end result of a hacked S200 would be the same of a standard TyTn or a standard P3600... Are you sure the P3600 output is not stereo?

Pretty sure its not stereo, either that or the stereo separation is really poor because it sounded like mon to me. In saying that though when I paired my iTech R35 stereo bluetooth clip with it there was the option to tick headset mode & stereo mode but its too late now I've sent it back today.
The only dislike on my new P3600 is the position of penon the bottom! . I've used many pda, and the pen was on top! But for the rest I love it!!!!

You are right the stereo bluetooth output is not stereo. This is ridiculous. I hope this can be fixed with some registry hacking otherwise HTC has really screwed this device big time.
One more thing, the smooth black coating is comming of from the bottom where the stylus is placed.... That's s REAL bad thing, since this will eventually tear up more and more of the coating... And I've only had it for two weeks
default A2DP registry settings for Trinity is:
UseJointStereo = 1
please change to:
UseJointStereo = 0
that will fix the "mono sound" issue.
Question
So far what i read, the software for this phone 3600 is not fully stable,
Camera still delay..
Some bugs
additional question following,
Delay of standard programs opening?
How about the sounds quality (loudness and clearness) is it very good?
which one is really better if compare 3600 and 3300(GPS enabled), which should i buy... -_-"
Thank you in advance..
fantastic device
Got my Trinity since yesterday. I had several phones and pda before (Dell Axim x51v was the last one) but the Trinity is the best until now. small enough, fast enough... if I only could get MMS to work for vodafone germany...

Did you try these (manual entry and cab for Vodafone):

Tytn and Trinity 3G/UMTS should be the same
So far...the trinity is my new favorite thing..very stable (have had to soft reset twice to get the Wifi signal running after a sync while wifi was on) and lots of fun. Phone is great and signal with one bar or less is still usable - where my old motorola was no good with a weak signal...and i can now make and take calls from my office - where previously there was no chance with the motorola. This device does everything I bought it for -combine my PDA and phone into one device...

Fact:
Microsoft's A2DP implementation in WM5 is incompatible with certain headsets.
Certain headsets, such as many Nokia and Logitech ones, sound incredible (as good as wired headphones), whereas others, like i.tech or Jabra, don't.
This has been a subject of much confusion to WM enthusiasts, since these headsets sound great when paired with other devices, however when used with a WM device, a high pitched ringing/hissing and slight distortion is heard when certain frequencies of sound are played.
Some Pocket PC users have temporarily solved their problem by porting the Widcomm Bluetooth stack over from the Dell Axim series, however it is generally buggy and not available for all devices.
Fact:
Windows Mobile 6 Beta was released, and had even worse A2DP than WM5
When the beta/demo roms starting floating around, many of us who experience the problem had a glimpse of hope that maybe it would be fixed.
But alas, the A2DP support had many people re-flashing back to WM5. It was even worse.
Fact:
THE FINAL RELEASE OF WM6 SUPPOSEDLY FIXED THE QUALITY BUGS OF A2DP!
There is a write up about this here:
http://forum.xda-developers.com/showthread.php?t=310438
Basically, the new devices shipping with WM6 seem to be more compatible with a wider variety of headsets than its predecessors.
Headsets with the static, popping, hissing, etc... finally sound good even with the Microsoft bluetooth stack.
Some of the new cooked Roms are starting to use this new A2DP support as well.
Problem:
WM5 still sounds bad with A2DP!
Those of us who don't have WM6 upgrades available, or don't want cooked roms or beta versions, are stuck with the poor A2DP of WM5.
Solution:
SOMEONE NEEDS TO MAKE A NEW A2DP PATCH using the WM6 drivers!
Remember when someone first made the A2DP support for Tornado available in WM5? If your device didn't have A2DP to begin with, all you needed was AKU2, and this patch would install the signed drivers and make the appropiate registry edits and like magic we all had A2DP (albeit crummy with some headsets)!
Over time, other patches were made, some using AKU 3.5 and other later releases that promised the possibility of better sound. But all of them failed.
What we need now, is for someone who has an official WM6 device (or someone who has access to a decent cooked ROM with the new A2DP support) to help make a NEW patch for those of us who need it!
Anyone out there willing to help?
Hey everybody,
I hope this can start a bigger awareness/activity on the goal to get a usable bluetooth audio protocol with Android on the HD2.
The Story
There hardly ever are threads or posts adressing this, which I can not understand. For me personally this is one of the 5 most important features in my handset. For example I can live very well with having to reset my 3G connection from time to time, but I can not stand having no A2DP. (I loved how WinMo does this on the HD2, fading down the music to make navigational instructions understandable. before you ask: after having android I simply dont want to go back to WinMo... it would make me sad.)
The Problem
As of what I know, A2DP sound quality ist directly linked to something in the Kernels. Until Hastarin 4.x the sound was beyond ****ty, but then there was an improvement, though it was not mentioned in Hastarins changelog. Was it an accidental improvement?
Anyway, since then the sound quality has been on the same level, being kind of working, but with an awful weird overweight on low frequncy tones. This can not be leveld out by the amps of any of my receiving devices.
Since bluetooth pairing works so well, and the A2DP transfer essentially works, i hope that it can not be the biggest issue to get the quality straight. -for a dev or cook, I mean
Please start a lively and constructive discussion! Now! Find a fix, and be sure that my donation will buy your next beers/organic lemonades/what ever you're in to.
I dont know what are you talking about..I use A2DP every day with great sound quality..It would have been useful if you posted your configuration on the device, Rom, Kernel, Build, and Bluetooth headset so we could maybe try to help you out..
I use:
WM ChuckyDroid
Build is NexusHD2-FRG83_V1.5 with both Hastarin r7.7 and michyprima R11
Bluetooth headset: Plantronics p590 (quite an old one but works great)
Everything works great..please be more specific about your problem
Cheers
I use A2DP on a daily basis as well and it works flawlessly on ever build I have tried
Are you you kidding me?
Since i tried a lot of ROM/Radio/Kernel combinations i thought this made no difference... I was quite sure this must be a development problem.
right now I use:
WinMo CleanEx Rom
Radio 2.14
Mdeejay evo sense 2.3 with Hastarin r7.9
Bevore that I mainly used a Dutty ROM and the MattC sense v1.8 with basically every Hastarin Kernel.
I've testet it every time on two different A2DP enabled stereos, and as described the sound quality is poor.
Can others confiirm having a good (or bad) sound quality over bluetooth?
Zero issues on the ones I've tested.

Wich bluetooth device you are using?
Devices
Maybe you and everyone should post their devices to see if that is the issue. I have a plantronics 510. It works perfect in WM but doesn't even show an a2dp profile in any android build. I would love to have crappy quality if I could even connect.
BTW: what is a good working headset that is confirmed to work with android bluetooth a2dp?
Yes, the quality is quite low on A2DP. Tested on my SE HBH-DS200. That headset is superb in WinMo.
Mine: Miri19.1/2.15/FroyoStone3.2-Hastarin7.7

I use a Fujitsu Siemens BS01R on my home stereo and a Sony MEX-BT 2800 in my car. Both worked perfectly well with WinMo.
I currently use Darstone Froyo Sense, r8 kernel, with Motorola H17 and have zero BT issues or quality issues.

I have same headset and get excellent quality in Calls as well as A2DP. Calls may also vary due to network cond so I dont pay much attention to that one.
I am on m-deejay DHD 3.7 with my VBN Reloaded2 Alt ROM

I have a Sony MEX-BT2800 cd receiver in my 2007 Volkswagen Jetta which I stream to and the sound is crystal clear
I dunno...maybe has to do with the Winmo ROM?
My exact setup is in my signature...the only thing that I may use that would be different than most is I use Lithium as my media player. I dont know if the media player may have something to do with it
Bluetooth A2DP
A2DP is a bag of different codecs from decent to bad. All Bluetooth devices that support are only required to support the minimum codec (not very good). Better ones including AAC and Apt-X are available but cost a bunch for a device mfr to include. Some phones, like iPhone have a lousy codec (possibly updated in the next ios release), others, like Nokia, seem pretty good. The tubby bass is a signature of the minimum codec. I don't know if the codec can be added through the OS since it lives in the BT chip. If you have good stuff in the phone it doesn't help at the speaker/headphone end if they don't have it as well.
We should also push to make sure that AVRCP profile is also supported so we have remote control (missing in iPhone until recently).
