A2DP Volume Control - General Topics

I have an i-mate Jasjar and recently purchased the GlobalSat entertainment bundle (receiver and BT transmitter) to listen to music wirelessly. I like the way it works, but of course now want to see about upgrading to one of the A2DP roms.
My question is regarding volume:
On PPC devices I have owned, unlike Palm, the overall sound volume determines what goes to your headphones. So you cannot mute your device and have the sound come out of the headphones. My concern is that I now have to keep the volume on my device turned up high to be able to listen to music via bluetooth with A2DP. Is that correct? I'm concerned that if there is a glitch with transferring the music via Bluetooh I'll end up having music blaring out of my JasJar (which has unfortunately happened to me already when my headphone jack has become unplugged!)
Can anyone confirm/try this? Thanks!

When my universal is on vibrate the sound via A2DP is still fine, and is controlled via the software volume control, ie WMP. This has fooled me on occasion, when i disconnected my A2DP headphones, expecting the sound to transfer to the speakers, and then not heard anything. I would then find I had placed my universal on vibrate much earlier in the day.

Just curious, which a2dp rom did you use?

The Qtek AKU2 one.

Tornado is not design for the MDA Vario/Wizard

I want to thank you for the Tornado cab file and the idea of installing A2DP on my TMO MDA, it's something that should have been available by now by TMO. :wink: I know that the Tornado is not really designed for the Wizard, but your right it does work! I also have the upgraded 2.17 ROM which works great. But after complete and thourough experimentation with the Tornado A2DP, the MDA, and the HT820 the Stereo sound is terrible.
8) I successfully followed the installation instructions. Of course you do not see any real changes, except those done to registry, until you buy a BT Stereo Headset. Then you see the [ ] Wireless Stereo option. I also confirmed WITHOUT Tornado's A2DP, you don't get the "Wireless Stereo" option, but you can get sound on your HT820, if your patient and waste enouph time clicking the connect button, or smart enouph to use a utility called BTSoundON, but the sound you get will be mono on sterroids. However, with Toranados' A2DP you DO get STEREO, but the quality is not very good!
At first I thought maybe the HT820 was possibly not a very good BT headset. The sound was low, although volume was as high as possible, and the bass was not very good. This was testing Mp3's at 128kbs. So I tested A2DP using TCPMP, and it obviously made a big difference with the HT820 especially playing around with the equilaizer and preamp boosters, settings.
Then I put the HT820 headset to the test. I swaped the HT820 and the mini Stereo Headphones included with MDA. I did this in critical guitar moments of some music, and it was obvious that the stereo quality was much superior with the mini Jack Stereo Headset. In every case, with every song, the mini Jack Stereo Headphones won heads up, and actually made the HT820 sound terrible.
But was it the HT820, or the Tornado A2DP? I connected the HT820 to my BT dongle on my windows XP. The sound blew me away, it was AWESOME on the HT820. As a matter of fact I was able to walk half way across the house and still got music from PC. Furthermore, I was able to receive a cell call on MDA, while listening to music on the PC, and the BT820 handled it incredible, also confirming that it could work on two seperate paired devices, incredible experience! :lol:
My humble conclusion: The HT820 is a solid BT Stereo Headset that has incredibly good sound when tested with softeware that supports it. Games sound incredible on the MDA with Tornado's A2DP. But not sure if just using BTSoundOn and not A2DP would give same results with games. TCPMP deffinatly makes a BIG diference on the MDA with Tornado's A2DP and HT820 Stereo. But I will be happy when TMO or some Developer comes up with the official Wizard/Vario A2DP.
Thanks for the memories anyway, I will keep the A2DP on MDA for now, incase I find myself in a situation where I don't have the mini Jack Headphones available. And I will defenetly keep the HT820 cause they sound awesome on PC, and great combination of Music on PC and Cell calls from MDA. :lol:
Interesting post. I've got the HT820 on order and it should be here next week sometime. ITMT I'm using HP FA303's with my 8125 (Wizard) and the sound is terrific! Which, of course, leads us to a conundrum:
given:
HT820 is a great sounding BT Stereo headset
FA303 is a great sounding BT Stereo headset based on the fact that it sounds great on Wizard
Therefore, one would think that the HT820 should sound great on a Wizard too....
I guess I'll just have to wait and see.... I'll test the two headsets side by side when it arrives.
Something you could try would be to lift the relevant DLLs off the Qtek Beta Rom which had A2DP. Those would be Wizard specific for sure.
The HT820 does sound great on the Wizard -- I installed the Tornado A2DP hack on my Qtek 9100 earlier today. FWIW, the HT820 also sounds great on the Blue Angel (which is why I bought the 820 in the first place).

Jabra BT620 review with i-mate SP5 (stereo bluetooth)

I purchased a Jabra BT620 bluetooth stereo headphones and wanted to give an update after listen to them for several hours..
I updated my i-mate SP5 to add the A2DP stereo bluetooth mod.
First off I want to say that there is NO "high pitched digital disturbance/distortion" like I have experience with other bluetooth stereo headphones like the Moto HT820 and the Plantronics Pulsar 590A with my i-mate SP5.
Pretty comfortable .... did not notice any issues after wearing them for about several hours... To me the most comfortable stereo bluetooth headphones I have used.
The max volume level is not bad but wish it was capable of going a bit louder. the bass level was fair but not great..
I also got them to work with my computer bluetooth adapter. Also sounded very good.
Conclusion:
Comfort - 9/10
Sound Quality - 8/10 (no high pitched digital disturbance/distortion)
Weight - 9/10
Battery life - 10/10
ok. How do you rate:
Pairing.
Does the BT620:
A) pair up automatically when you power it up like the HT820
B) pair up when you press the mode button like the FA303
C) require a refresh in bleutooth connection settings to pair like many others
Phone headset profile.
When a call comes in does it automatically switch to headset profile?
When placing a call, does it automatically select headset profile when the call connects?
Is there a headset profile specific button that will bring up the voice dialer when pressed?
AVRCP
does this work?
does it pause music when phone conenction occurs?
I really want to buy this headset but will take a pass if I have to go into bluetooth connection prefs everytime I want to pair....
According to Jabra's specs, this device is certainly capable of AVRCP based music pause/resume.
they automaticly pair in headset profile , but in order to get wireless stereo you have to go to connections->bluetooth-device and set as wireless stereo each time.
wish there was a fix for this, at least some sort of shortcut
AVRCP based music pause/resume/next works very well

Bluetooth headset.

What bluetooth headsets will work with the touch diamond?
other question: why should there be any headsets not working?
i have a really cheap but nice looking samsung headset, no problem to get paired with the diamond. should work with any other headset, too!?
My existing is just a cheap iTouch bluetooth headset and it works perfectly.
I don't think Diamond has any problem to work with other brands.
I have an old Motorola Bluetooth headset (4 Years) and it will not pair with my Diamond. Looks like its time to upgrade to a Jawbone!! hehehe
i have the jabra bt3030
its a stereo bluetooth headset working on A2DP
works great and looks awesome!!
So can I listen to music through any bluetooth headset (that has headsets to play music)?
My Plantronics P590 works like a charm

Say something about the sound, it is better (or/and louder) then original HS or same quality?
Here you go!

Theres a app called btAudio (keep a google-eye open for newer versions) that does exactly this, it will send ALL sound to the headset, despite of what windows had in mind for the sound (as in if it was gonna use headset or build-in speaker)
Tho, it sometimes chokes when you dont shut down the app before you disable the bluetooth headset or phones bluetooth function, but i guess that kinda makes sense (its even sayd in the program to not do that, but im a sucker for trying such things hehe)
And another thing, this happend for me too (taken from comments on some site, linked below)
The program runs well however if you try to make a phone call with the blue tooth ear piece while the program is active the program is not available after the call is completed.
I had to reset my phone to enable the program again. - source of comment
Guess thats related to windows not being to happy theres multiple apps using the headset, lets hope for a next version which auto-disables when calling and re-enables when u hang up.
I'm waiting for this one (Jabra BT530, due end August according to Play.com)...
http://www.mobilefun.co.uk/product/16778.htm
Got the manual that Jabra put up on their support site for a day or two before taking it off. Manual says it also supports A2DP and can stream music.
And what about battery life? Could somebody using bluetooth stereos write how long the Diamond can last, and what is the overall impact on battery life while listening to music?
I use this headset, its got very good sound and is also nice and comfortable, since i have my tragus peirced i cant wear "normal" headphones!
http://www.amazon.co.uk/Sony-DRBT20...6?ie=UTF8&s=electronics&qid=1216998998&sr=8-6
It also works on my pc and my PS3 as a wireless headset/mic!
I have proper enclosed stereo headphones Dell DH-200 with volume control, next and previous track plus play/pause buttons and it all works fine with HTC DT. The only think I am not sure about is which profile it is using, the sound is not as good as when I have it paired with my laptop, which would suggest a low speed profile as opposed to HQ.
You can change the bluetooth profile in Schap's Advanced Config. I've set bitpool to 70, max to 76 and min to 64. Now the sound quality is waaay better.
I can't connect my Jabra 320's (worked with SE W880i) to BT Stereo, it only see's the headphones as a handsfree unit on the HTC
Jawbone. Nothing else comes close (for hands free anyway!). And the new one even matches the Diamond... sort of!
Has anyone suffered the sound periodically dropping out for a second or two, mainly during the first minutes of connection but still persisting now and again several tracks down the playlist?

Fuze - connect A2DP to car stereo for music, and HFP to Jawbone at same time?

Hi,
I searched the forum, wiki, etc., but didn't find an answer.
I have an AT&T Fuze with the stock ROM (WM 6.1). I know the Fuze is supposed to support multiple simultaneous bt connections. What I would like to do is connect A2DP to my Pioneer stereo for music playback, and also connect handsfree to my Jawbone 2 headset for phone calls while in the car.
I can successfully connect A2DP to my stereo for music by itself.
I can successfully connect HFP to my Jawbone 2 by itself.
I *have* managed to connect to both at the same time, by staying on an active phone call with my Jawbone, then telling my Fuze to connect to the car stereo. However, no music could be heard (from either Mortplayer or WMP). The phone call stayed up just fine though.
Anyone know if there's a way to get both working at the same time?
(And before you ask, I would just use the hands-free capability of my Pioneer stereo for phone calls too, but I've found my car is too noisy for anyone to hear me with the Pioneer's microphone unless I hold it right in front of my mouth, which defeats the "hands free" goal...)
Thanks for any help you can offer.
Best,
Chris
In your case I do not think that is possible since the concept of being able to juggle 2 devices at the same time requires 1 to relinquish control while the other goes active. It turns off the music so you do not get distracted while talking and reconects the music after the call is over.
It seems to be a software protocol if anything. Yes both can be connected at the same time, but both cannot be "active" as in doing both music playback and voice calls.
I have a bt headset that handles 2 profiles at once and according to the protocol, if a call comes in, it pauses my ipod and then picks up the call and then resets back to normal after the call.. Either you have to mess with the coding itself or someone has to come up with a workaround, but I do not think that is possible.
Thanks for the reply. I had hoped it might be possible for the Fuze to route stereo audio to one BT profile (A2DP), while non-stereo audio (e.g., phone call, system tones, etc.) to the HFP profile, almost as though the profiles acted as addressable "service ports" (ala HTTP, SMTP, etc.).
But, unlike with TCP/IP, I admit to knowing next to nothing about how the BT stack works and how profiles are applied to certain types of data (or, how data is routed to a given BT association based on profile).
Thanks again,
Chris
well the thing is.. the fuze can connect to multiple devices simultaneously, but based on the music and voice call order, it is prohibited from doing both at the same time. so therefore when there is no call, the music plays, but when a call comes it, the music is paused and resumed after the call is done. (obviously the call has higher priority here).
My only suggestion is to leave it as it is since it is done so that you do not get distracted while talking and probably while you're driving.
Multitasking is difficult when you're listening to 2 things, responding to 1, and driving at the same time. The more you multitask the less you are able to devote to your main activity (in your case, driving).
but yeah. if you can find someone who can mess with that and allow for both to be active at the same time, then congrats. Otherwise just think of it as a safety measure.
Except that, when I had both the headset and the stereo connected to the Fuze, the music *didn't* pause. It just didn't output (as though the volume was muted). In fact, in both Mortplayer and WMP, it appeared as though it was playing at ~2X the normal rate (just watching the track playback time counter).
I know what you're talking about re: listen to music, call comes in, music pauses, call ends, music resumes. That's the behavior I get when I use the car stereo for both handsfree and A2DP.
The behavior when connected to two different devices seemed to be different, though, so I hoped that might mean it was in fact possible.
-Chris
yeah I know what you mean, but maybe the fact that it tried to do both tripped it up and so it took the call as a higher priority and focused the data towards the call.
atleast that is what I think.
I have almost the exact same configuration, except I am using a Sony car stereo but have a jawbone. What I have to do every time I get in the car is the following.
1. Let my stereo connect to both hands free and wireless headphone services.
2. Open bluetooth settings
3. Manually connect to my Jawbone.
It works great.
ATT Fuze
Energy Rom 072209
Old jawbone
Sony XPLOD Car Stereo
I'll also add it's pretty neat to be able to push the jawbone to activate MS Voice Commander and choose what music I want to play over my car stereo.

Thanks for the reply. I'll give that a shot. I'm not sure that my Pioneer stereo will automatically connect both handsfree and A2DP. I know it will do handsfree automatically. We'll see...

BT sound in Car

Hello, my new car has a bluetooth support, that if I keep my fuze with bt turned on, when the fuze rings it ring on the car's sound, if I answer it works by car's sound and the BT integrated mic, and when I call also, it works the same way.
I'd like to transmit my fuze's sound I hear on WMP, or TCMP right to the car's sound, so I think I would have to configure car's sound as a handsfree.
Would anybody know if the bluetooth's sound would have a good quality? And if there is a away for transmit it?
Thanks
if the car's bt support a2dp you can choose it as wireless stereo under bluetooth settings
if it don't support that you cant
I can't see any configuration about it. what is this a2dp?
My car's bt is only a button, that u press two times to call, and one time to answer, it configures automatically, and I can not see anything about it.
http://en.wikipedia.org/wiki/Bluetooth_profile#Advanced_Audio_Distribution_Profile_.28A2DP.29
Rudegar is right - if your car supports a2dp you can connect the device to your cars stereo. However some car maufacturers offer upgrades for BT-audio for their car stereos (Audi for example) if it´s not buil in originally.
I have a Sony car stereo (BT5100) and tried it with my touch pro. The sound quality however is fairly poor. I have tried different audio players with no improvement.
hippokrates, any idea if the built in bluetooth in a BMW M6 supports a2dp?
I found a PDF-File on the BMW Homepage. Apparently they don´t support a2dp (even though they don´t specificcally mention it) but offer so called snap-in adapters for a bunch of cellphones. Unfotunately the TP is not one of them. However, they tested the BT-functions (hands free protocoll and SIM-card access) and they are officially working with the touch pro. But I suppose you found that out allready ;-)
H, thanks for that. I couldn't find it on the BMW site. The bluetooth does work well with my TP in the M6. I only use it for the phone, which works very well. I'll have to experiment with the music and see if I can get that working. I'll report back.
