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)

I also have this Problem. Sometimes, i have to press, the button twice, sometimes i have to hold it. But the problem apears only, on resume.

Yes, that's realy evil ... I also have that. Reconnecting of Handsfree works fine.

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;

You can see my (and some others) experiences with A2DP and some stuff we have tried to fix/handle it as good as possible;

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

How do you play sounds over bluetooth ?
I'm trying to understand the routes of analog and digital
sound data and how to control them.

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).

Software is not a problem. We need to understand
what the hardware is doing.
I see many posts regarding poor stereo bluetooth performance on the forum so I thought I would share my findings. The WM5 operating system on my TyTN is listed in my user CP.
I would like to advise the forum of my findings on my TyTN, updated with the above ROM. The .exe version includes Radio 1.34 and if of course it is AKU 3.3.
So far I have not encountered any major issues with this test ROM and my findings have amazed me on the A2DP performance.
The only mod I had to make was to change from mono to stereo in the registry. Apart from that all is standard with no bitpool changes necessary. It was also not necessary to add Sleuths A2DP fix.
I have tried both my Nokia HS12-W as well as the HTC BH S100 Bluetooth Stereo headphones. The results are fantastic with good sound and functionality. The range in an open area is up to 15 metres and more.
I was very impressed with the BH S100 because I can also plug in my favourite Sennheiser earphones for extra comfort and quality.
The functions are practical and the voice quality of the microphone is also very good.
In South Africa it is well priced against the competition and much cheaper that the HS-12W. The latter features an FM radio, which I never used in any case.
The HS-12W had to be used with fixes on the SA 1.35 ROM(Bitpool adjustments and Sleuths A2DP fiX) and skipping would still ocasionally occur. The range was also not more than 4 metres on the HS12-W. The HTC product is a new aquisition.
Hope this answers some of your questions.
How do I get the download?

FM recorder
Can anybody provide program for recording FM programs. THe same was present in O2 Atom Life.
Thanks in advance
Re
Surprising not even single reply at such a Forum
I hardly think this will help but you can record radio with Resco Pocket Radio... There are tons of channels to choose from.
I know it's internet radio and not from the built-in FM radio, but I thought it's better than nothing.
I miss this too. I used to record stuff all the time to listen back to later. I'm sure some one must be able to extract the atom radio app and port it to the diamond, it's just a question of if they wanted too. I'd do it myself if I knew how
hi all after plugging in headphones to my htc hd2 i find the default htc radio not get a very good signal at all, my older omnia1 got a great signal all the time but this ones iffy as hell, will installing another radio app work any better or is it juts a **** radio reciver built in
i live in Nottingham, uk and have tested the stock htc headphones, shure se310 and also the big sennheisers hd595
are there even other apps compatible with the FM hardware
emmm i tought all apps were compatible with all fm radios ?? am i wrong to think this
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).
