Universal's A2DP Quality

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)

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;
http://forum.xda-developers.com/viewtopic.php?t=53717
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).

Qtek 2020 headphone connector broken :(

Hello all,
My Qtek 2020 (Himalaya PH10B) fell on the floor with the headphones on, and the mini-jack for connector for the headphones broke inside it.
I successfully opened it, and I was able to see the damages. I can see only 6 pins that connected the mini-jack plug to the main board, and it seems that there could be a seventh that got broken...
Would anyone of you know of a closeup picture of this headset plug/connector ? Do you know if it is possible to find a new one ? If not, mine looks reparable still, but I would feel reassured if I knew the exact connection here
Thank you in advance for your help.
Cheers
Thomas

http://forum.xda-developers.com/showthread.php?t=225372&highlight=connector

Thank you for your answer Rudegar,
I re-soldered the connector, and I realized that a pin was indeed missing. I actually found it freely moving inside the PDA, but I could not solder it back to the connector. The results ? Well, it still does not work, unfortunately... With the headset on, it is mainly okay (there is still a little contact problem) but *withou* the headset, it still has no sound...
So :
1) Can I find this connector somewhere ?
2) Is there a way to tell the PDA not to check for the headset, and use the main speaker all the time ?
3) Would it change anything if I bought a blutooth headset ?
Thank you in advance !
Cheers
Thomas

1.) i doubt it would be a cheap option if htc had a special connector made just for their phones so i'd asume they use some sort of std component
and maybe there even is a partNr og serial on the connector
which could be used to find a replacement in R&S catalog
http://www.rs-components.com/index.html
2.) no pretty sure the switch between headset and internal speaker is don in hardware and software cant control it
3.) no with bluetooth headset you just dont use the audio connector which mean it would be empty and you'd have no sound on the pda
but it would prob solve poor contact issue of your current headset

Thank you Rudegar !
I am going to re-open it and check if I can find any serial # on the component. It looks like it is my best option. Obviously, if I find something, I will post it on that forum, so that other people can know...
Thanks again !

Bet You Xda Experts Can't Solve This One...

I bet you XDA experts can't solve this one:
I used to be able to connect my Mogul to my car stereo, via the analog headphone jack, and then take/make calls using my bluetooth headset all at the same time.
But after updating the firmware in my Mogul (I think it was the upgrade to WM 6) I was no longer able to do this. And now, while playing music with the Mogul, when a call comes in I first have to physically unplug the phone from the car to be able to hear the caller on my bluetooth headset.
Is there a registry fix for this problem?
**UPDATE**UPDATE**UPDATE**
Good news!
This one was solved by ATOMCLOCK!
The link to the thread containing the fix is HERE.
Here is the fix as quoted from his thread:
"I found the fix!!!
This is the registry key
REGEDIT4
[HKEY_LOCAL_MACHINE\SOFTWARE\HTC\AudioPath]
"AudioPathSwitchToWired"=dword:00000000
If AudioPathSwitchToWired = 0 then bluetooth will be the primary output
If AudioPathSwitchToWired = 1 then usb audio will be the primary output (Default setting)"
Thanks ATOMCLOCK for your persistence in solving this issue.

Not enough information here to help you (need ROM / Radio versions, etc).
Reflash the phone with no other programs installed and try to see if program still exists.
I do this all the time with no issues on 3.39 and 3.1.6, must be your configuration.

Here is my info:
Phone: Mogul on Sprint network
ROM: DCD 3.1.2
Radio: 3.39.10
I'm using a Y-cable that separates power (female USB) and headphone (female 3.5mm stereo) connections.
I then have a USB cigarette lighter adapter for power and a standard 3.5mm male/male stereo cable going to my radio's aux input.
This all worked flawlessly before upgrading the ROM to the first one that included Windows Mobile 6.
And yes I have tried re-flashing several times and with different ROMs.
Could it be a hardware problem?

Hardware failure - any expert?

Hi, I'm in trouble with my wizard, I don't understand where the problem is, but it's related to the speakers:
- the lateral speakers works when I recive a call, they play my ringtone
- no sound at all when I setup the ringtone and I test it
- no sound at all when I play windowsmedia
- no sound at all when I make a call (no lateral no central speaker)
- bluetooth headset works perfectly
- every other function work perfectly
I opened my wizard but all the concetors seem ok... What's happening? Any expert that can help me in finding the problem?
My configuration:
- Imate K-JAM G3
- WM6 Wizard_19855_Clean_V1 (but the same problem with original rom and other 5 roms that i've tested)
- radio 2.25.11
Thanks to all that can help.
Andrea

SOlved
I don't know why and how but after a fresh reflash of the rom (I used an ITA one) everything is working good.
I have no idea what happened.
Now it's ok.

FM Radio via Bluetooth Headset

To one and all,
Two purposes for this thread:
Generally - I'm hoping it will be a good place for all the people (like me) that have tried to get a solution for this issue in so many forums (over so many years)and have simply been told "you need the wired headset for an antenna", to register their interest in a solution - hopefully a bit of chat and interest will finally yeild a solution. A simple +1 should suffice.
Specifically - I listen to FM Radio via my wired headset on my windows mobile device for about 3 hours a day what I would like to do:
I would like to use my wired headset (or some alternate antenna solution - for me to choose, ultimately providing a suitably strong FM signal to my device).
I will then conceal this antenna (depending what it is will depend how I do it (no rude remarks required ;o) )) and then put the mobile phone and the antenna in my pocket.
I then want to listen to FM radio via free to air (not streamed via the internet - data in AUS is expensive, I don't want a sub thread about who I'm with and alternate data plans) A2DP compliant bluetooth stereo headphones.
I am not asking for RDS, although I may look for a radio app with this later.
I am not asking for TMC.
I know this will drain my battery - I can manage this.
I know I could continue to use my wired heaset, however, I and many others based on my XDA and general iternet searching would like a nice simple solution to the above if any developer(s) are able to assist, I and I believe many others with similar non-existant coding skills, would appreciate it very much.
I am not intending to be rude, I have tried to be very specific about my requirements, I am trying to demonstrate that I have done some research and have hopefully highlighted that I do not need any "you need the wired headset for FM Radio therefore it can't be done" type answers.
I am very interested in this community and it's ability to rise to the "I can do that" approach which is why I am posting here.
Any feedback, greatly appreciated - especially if you can point me in the direction of a solution!
Kind regards
apj_apj

How to hide the antenna, I do not know, just using a small adapter with USM for Jack, he was short and easy to hide from the waist bag in his pocket jeans.
Even better quality of reception.
And to transfer the sound to Bluetooth use the excellent program BTFM Radio v1.51

Thanks very much mrTag. I've downloaded the application, can't read or translate the readme.txt or the whatsnew.txt so will just have to have a go I suppose! Does anyone know where there is an English equivalent?
My new windows mobile arrives in about 2 - 3 days, my current one died, so I will let you know how I go when I get it and try it out.
Thanks again for the quick response and the possible solution to my problems!

Here is a rough translation

o Record audio (including radio) "on the fly to mp3.
Supported bit rates: 32-320Kbps, stereo.
Directory of audio-recording is set up, you can use a memory card.
(bitrate affects the download)
(!) To carry out the recording must have EmzMp3EncDll.dll in the directory Windows.
(EmzMp3EncDll.dll initially present on the Samsung i740)
o Automatic launch and management of FM Radio.
(Adjusting for the application supported)
o Close the program and launch a selected application from the command sets.
(S2P default)
o Management of all functions of the program directly from the headset.
It supports AVRCP.
Fully to orig. FM Radio Samsung i740, partly for other devices.

Play_Pause - start / stop transmission
Stop - search / switching stations to a standard Radio i740
(length, pressing Play_Pause).
Forward / FF - leafing forward (Right click you send to the radio box)
Backward / REW - searching backwards (pressing a button sends the Left in the radio box)
FF dL. Pressing - start / stop recording
REW dL. Pressing - to close the radio, run a given application
(such as S2P)
Long-click option is confirmed by a beep, then you can release the button.
(default is playing default.wav)
Broadcast radio is available at:
Samsung i740
RoverPC N6
RoverPC V7
RoverPC X7
HTC Touch HD
Samsung i900 (only when using the headset with a microphone switched)
Possibly incompatible with other devices.
If your KVM is not on the list, but successful radio broadcast, please send me
the name of your KVM to supplement the list of compatible.
(!) When the button will not work, use the S2U2!
Use:
1. Connect the wired headset as an antenna
2. Try and include radio
3. System volume to maximum, the radio volume to maximum.
3. Connect A2DP headset, and open the Audio Gateway
4. Run BTFM_Radio

This sounds like the answer to my problems too. The only problem I have is the link doesn't seem to work ("resource not found" message). Any ideas?

Indeed, the site is unavailable.
You can put files here.

I've been trying to listen my HTC Topaz radio via my Bluetooth CrashHelmet.
This works - allbeit just one speaker (mono).
Great Thx!

Almost there!
@mrTAG,
I've given BTFM Radio v1.51 a try on my Acer M900 handheld. Its native FM tuner application allows toggling the sound between the wired headsets (which act as antenna) and the device's loudspeaker.
I can't read anything in russian, but I've noticed that BTFM Radio broadcasts sound to my A2DP headsets only when FM sound has been toggled to the loudspeaker, and I tap on the upper left button on the application's screen. Nevertheless, the loudspeaker sound is not cut off at all, for what I have FM sound coming from both my A2DP headsets and the device's loudspeaker. There's not much point in such a behaviour, don't you think? I wonder if I missing some settings, due to my complete ignorance in reading russian. Any hints?
Furthermore, could you give me some guidance in reading the application buttons and settings in general, because I don't have a russian keyboard to try to enter what they are showing, on an online translation tool.
Thanks, anyway.
Cheers!
Carlos

I am unfortunately not a developer program.
Try to disassemble the program and translated into English.
But I'm afraid you do not help, most likely your device is not supported

I was looking for a program like this. One question: does this app integrate well with calls? I mean, if you're listening to radio and a call is received, radio is stopped and you can handle the call? I have a a2dp headset for my helmet and it would be great to be able to listen the radio and answer the calls while riding...
Thanks!

i am going to try this program with my Samsung omnia i900.
And btw, i found out a way to translate the notepad and readme to
english. please find attached files for he english translated readme and whatsnew.txt from the files.

I wonder if your A2DP connection was already active, before you tapped on the first button. I don't read russian either, but I remember seeing a popup window once, when I had forgotten to activate A2DP beforehand.
Well, just for the records, after e-mailing Dmitriy, the developer himself, I've been told that the 1st button is "Start", the 2nd one is "Stop", the 3rd one is "Record" (provided that you have EmzMp3EncDll.dll on your \Windows directory) and the 4th one is "Exit".
Just my 2 cents...

I tried it also on a Samsung Omnia i900 but it doesn't affect the radio output, unfotunately! Sill unable to listen to the radio FM on the bluetooth headset.

cool, works for me but i have the radio playing out of both my phone speeker and my bluetooth headset...
any solution? if i turn down the volume it also turns it down on headset...

waiting on my stereo BT HS, meanwhile tried with mono and dosnt work, after playing with it (i dont read russian) when i change advanced bt audio setting to just audio headset goes into feed back like mic is wid open but no radio, i am hoping it will work when i get stereo HS.
FYI i have anadapter for 3.5 & charging and that allows me to listen to radio without the HS that comes with the phone i note these have 6 pins inside ware mii usb for connecting to pc has 5.
thanks for this program either way i've been searching and its closest i've come yet.

Here is the reposted link for the app hope its of use for all

After trying al lot off "software-solutions". I've got the best result with a little conector on my HTC Touch Diamond2 T5353 (HTC Topaz 100).
It's a little thing wich you can plug in via mini-usb, and out there is a headphoneconnector (mini-usb), mini-usb and an audio-jack.
In the audio-jack I plug in my bluetooth adaptor (dongle) of my blackbeat906 headset.
So I save my phonebattery and the adaptor works as an fm-antenna.

Hi ,
Much appreciate your having posted this file in the forum as its unavailable at the earlier mentioned url, however I'm unable to download it it gets downloaded as a .php file and not the .zip file its meant to be.
Also would this work on sony ericsson Elm ( I need a Java version please....)which has its inbuilt RDS radio.
many thanks
Best Regds
