Low sound quality with 6700 and Moto HT820 headset

Hi All,
I am new to the forum. I have owned a PDA phone for about a month, a Verizon (HTC/Apache/UT Starcomm/Audiovox) XV6700. It was rebadged so many times, I have no idea who really made it.
I read about A2DP Bluetooth technology. I also read reviews of several headsets before purchasing the Motorola HT820 headset.
I loaded up a two-gigabyte mini-SD card with mp3 files, popped it in, paired the headset to the phone and engaged Windows Media Player.
Unfortunately, the sound quality is horrible. It sounds as if I am listening to music played over the phone, as if I am on hold with some customer service call center. I know the headphones are capable of much more because they come with a stereo mini-plug cable. When I plug them into the audio output on my laptop, the headphones come alive with decent sound quality.
I did not modify my registry or add .cab or .dll files. When I paired the headset with the XV 6700, I just checked the "hands free," "wireless stereo," and "headset" options.
Am I missing something or is this the sound quality I can expect from this technology?

Make sure you have the new ROM update for the Verizon VX, and install the Tornado cabs and dll files.

A2dp on xv6700
I have updated my rom, made the Tornado changes, made other reg changes as described in this and related forums - all to no avail. Stereo Sound is constantly clipping. Phone sound is ok.
What else can I try
Feel free to email me direct.

You may want to try another player, like pocket player. Or try another BT stereo headset. If that dosn't work you may want to try getting your device swapped out with a new one. I can't get it to work on my PPC6700, but am waiting for a fix of the EVDO/ring through problem with newer units before I try to swap mine out.

xv6700 a2DP lag
I have already tried the pocket player - no difference. I am also on my second headphone set (albeit from the same vendor).
Unfortunately Verizon will not swap out because an unsupported feature does not work. At least that is what they told me.

Don't worry you are not the only one that can't get it to work.
The bluetooth on the 6700 is not very good, so YMMV when it comes to A2DP. It is a unsupported feature, you may need to convince them the BT is bad, but don't mention the A2DP.
I am waiting for a fix of the EV-DO ring through problem on the shipped PPC6700 with the new ROM before I have Sprint look at mine.

XV6700 A2DP lag problem.
Unfortunately without A2DP "enabled", the bluetooth connection seems to work just fine.
BTW: What is the EV-DO ring through problem?

It dosn't apply to Verizon VX6700, just the Sprint PPC6700.

Low sound quality with 6700 and Moto HT820 headset / A2DP
I am new to posting, be kind please. I have spent a lot of time and research on this problem and I am having some luck and some other problems that there may be some great info on. I do have the latest firmware from UTStarcom (Verizon model) which has AKU 2.0 update. I did install the tornado A2DP I found here and it did not work at first until I found the additional Tor_A2DP_cert.cab file and installed it. It works and seems to be stable, including headset operations. The only problem is sound quality. There is a ringing like high pitched digital noise, my experience in electronics would have me thinking of a bandwidth limitation, or timing issue that would be a result of process priority or something, just guessing! I have the Plantronics 590a stereo headset that sounds great when using the BT with my laptop, so I beleive it is with the phone. The big question, has anyone tried changing the registry settings concerning bluetooth? I see some entries here: HKEY_LOCAL_MACHINE\Services\BTAGSVC and HKEY_LOCAL_MACHINE\Services\BTHIDSVC don't know what they are or what they would do, not brave enough to change them.

I have two BT Stereo headset, 2 different A2DP devices, BT laptop, and a BT dongle and get different results with different combinations.
- Southwing SA505 Bluetooth Stereo Headset (works great with everything, questionable manufacture quality, broke after 3 months of use)
- Moto HT820 Bluetooth Stereo Headset (good quality, but BT functions & sound is problematic)
- Cing 8125 (running Faria Crossbow WM6)
- LG enV VX9900 (vanilla os)
I believe it is just a simple case of both Bluetooth software of your device and headset not getting along together.
The SA505 works perfectly and sound quality is awesome with all A2DP & BT remote devices (including both devices, BT laptop, and a cheap generic usb BT dongle installed on my desktop)
The Motorola HT820 on the other hand is quirky...
Paired to the 8125 - when listening to music, sound breaks briefly (for 0.5 - 1.5 secs) randomly every 30-60 secs. Everything else is fine including sound quality.
Paired to the vx9900 - it unpairs when getting a incoming call & I have to manually pair it back up. Everything else works fine including outgoing calls. Good sound.
Paired to laptop or BT dongle - works perfectly.
in short the only thing that could be done is on the handset side by changing the BT stack or rom.
hope this helps.

Just try MSI Blue Player, this is the only PLAYER which post a high quality sound to my bluetooth ear piece.

VX6700 and Bluetooth
Just as a friendly note, I had the Verizon VX6700 until last week. I had tried numerous bluetooth headsets with it and all seemed sub-par or totally unacceptable. The last one I tried was the Southwing SA505 and was, to say the least, displeased with the sound quality. I shelved all my bluetooth headphones and continued using the Motorola H700 earpiece for phone use only even though it was hard to hear in noisy environments, but was the lesser of all evils. Last week, I was available for upgrade from Verizon and got the LG Chocolate, took it home and put some music on it and used the plug in style headphones for the first day. After getting sore ears from the round-stuff-them-in-your-ear-hole type headphones, I decided to try the Bluetooth headphones again for the mere humor of having spent over $200 on the lot of them. The Southwing SA505 sounded phenomenal on the Chocolate. I then tried talking to my wife driving down the road with the windows rolled down and going 65 MPH, which had always been a problem before. She actually sounded like she was right next to me in crystal clear stereo (which if you have been married 21 years as I have, then you understand what a scary thought that is). I don't think the problem you are having is the headset but rather the phone and unfortunately I have no answer how to fix it, but hopefully have steered you in the right direction of where the problem lies. Good luck to you.

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.

AD2P is not really stereo

hi all
i just discover few days back that i realised there is quite difference in stereo sound when i use bluetooth stereo on laptop compared to my dopod.
is there any setting that can be done? Will sound equalizer (is there any?) helps?

Does someone have any idea what happens

Add some more:

Thank you, .... sound is much better now .... just now, I am missing the naviplay where the trebles where much better than with itech R35 or S38, I have at the moment....

thanks...it's more stereo now but now i'm experiencing"hissing"sound which never
before. can i adjust it to any other value? is there any combination i should follow?
thanks..

I found that "hissing" is dependant on the headset used.
My plantronics have almost no hiss, while my cheap i-tech things have lots.
Anybody else have the option to compare different headsets?

I use Samsung H200 for Handsfree - it has a sligt his when it initially connects which disappears as soon as the call is connected.

My Plantronics 590 headset has no hiss and sound absolutely clear and crisp.

Maybe the right placeereo head set and I paired it with my 7500 as a stereo head set

And your problem is?

Oooooooops...
I didn't realize the whole message was missing,it is like when the celular line fails and you keep on talking...
Well so I have this magnificient Motorola headset S9 and I sucessfully paired it as a Hanfree and a Stereo headset
Everything is working perfect,except the fact that when I activate the voice tag (which usually with oter BT headset works perfectly) I cannot hear the beep telling me to say the voice tag and also I cant hear the confirmation (that the PDA understood what I said)
The voice tag DO work and if I am lucky it dials what I say but I can know only when someone pickup from the other side ....
when i dis-pair the stereo headset,it is working again.
I know it is not the most horrible problem reported in this forum,but if anyone can help....

How to play music via bluetooth device
I've got a set of Harman/kardon Soundstick II speakers and i wan't to play music wirelessly from my laptop (HP Pavilion dv6000 series) onto it i.e I don't wanna plug the speakers directly into the laptop.
I bought the Sony HWSBTA2W Bluetooth Transmitter/Receiver and have managed to connect/link it to my laptop. The problem is however, how do you get a music program such as Windows Media Player to play music via the Sony device. I have managed to play music from my Nokia 6600 phone through the device successfully but am unable to play music from my laptop.The Sony device appears as a bluetooth headset in my list of bluetooth devices, but does not appear as a speaker on my laptop.
And oh yes, my laptop is wireless and bluetooth enabled.
Or Is there another wireless dongle or bluetooth item of some kind that i can plug my speakers into and will stream the music down from my laptop.

BT voice commands with TomTom?

Is it possible to send voice commands from TOM TOM to a bluetooth enabled device?
What are the settings? I can get the voice commands to work with my Jabra headset but not my receiver...
I just got a nifty car receiver that takes A2DP music and phone calls. GPS routing over BT would complete it!

I did some more testing.
It seems that the tomtom signal comes over the A2DP bluetooth signal.
So on my car stereo, the tomtom commands will come through, only if I have the stereo on bluetooth mode. Not the best if you wish to listen to the radio.
Is there a way to force the tomtom commands over the HCP (Hands Free Profile)? That way the voice commands will be forced to the car stereo and interrupt radio play.
kww

there used to be a registry patch or program that peeps used to use to allow them to listen to music through the BT headset. This was before A2DP existed hence the need, most peeps dismissed it because it was mono and poor quality audio (like listening to your music over a phone line,) but I have a feeling it is exactly what you are looking for !

I have downloaded a couple of programs, but they don't seem to work.
What is needed is some sort of program where you can pick the software to rout the audio either to a2dp or HFP...

the software im thinking of gave the choice of routing ALL system audio (including music) via headset profile bluetooth or not, at your choice !! trust me, it is what your looking for.

Problem is, most of those programs are/were pre WM5 and don't work with WM6, BTaudionav is an example. Regardless, if you come up with a software title, let me know.

you should search in the forum for the universal, that is where I would have seen it, as that is the phone I had at the time, It shipped with WM5 but was a long time coming with a rom that supported A2DP, in the mean time these programs popped up !

just stumbled accross this
http://forum.xda-developers.com/showthread.php?t=278778&highlight=a2dp

I am going to read through the entire thread, but the line of code that says:
"UseJointStereo"=dword:00000000
just turns off the A2DP; 00000001 enables.
Further, it routs all A2DP to mono.
Got through the thread, it really doesn't do what I want.
What I am trying to do is to have music port to A2DP stereo of my car receiver as normal, and have TomTom audio commands to the HFP.
That way you can play music over bluetooth, and when tomtom audio starts, it will pause music play and the tomtom command can be heard loud and clear.
As of right now here is what I can do:
TomTom audio commands via A2DP to car stereo (makes for a boring ride)
Music via A2DP to car stereo
Play both music and TomTom over A2DP, but music player is NOT interupted when a TomTom audio command comes through
I am going to search the tomtom forums, but I doubt I will have any luck there.

I see what your trying to do, and it is true there is nothing that quite manages it, the problem is that tomtom would have to be written or modified to use HFP when the commands are played, the best you could hope for is to reduce the volume of your audio to ie 70% and leave tomtom at 100%, this will make the tomtom commands really standout when they are played.

That would be a good compromise, thanks.
fwiw, I have the question into tomtom support, but doubt if those monkeys can do anything...

I hope you get a result, but as you already know, their support is useless

I have read a bit about mort script. I have to learn more, and perhaps there might be a way...

Try Teksoft BlueMusic, this routes all audio to headset.
I used to use it with Skype on the Athena, till I found Fring.

Bluetooth for audio output?? Can't get to work!

Hi,
I've got a 3xx series Plantronics headset and i've got a question about using it for more than JUST calls.
Can I use it for watching movies?? at the moment, when the movie plays, it automatically goes to loudspeaker, even whilst paired.
I know of something called A2DP, but I'm not sure that my BT headset is that... Can I install something or change some setting to make the music/movie play through my present headset??
Thanks!!

A2dp is a stereo profile, should be active if you have a stereo headset and are listening to anything stereo on the phone. I've been having trouble getting A2DP to stay active on my phone as well, but I just read about a program called A2DP Toggle found Here seems to be working for me tho I'm not sure its what your looking for.

Well I don't own a stereo BT headset. Just a normal one-ear one.
I want to know if there is a way to port the movie/music sounds through it.
So I think its a bit different to your case. Anyone else?? Thanks

btw, I've used a simple bluetooth headset with my PC before and it ported all the sounds from the PC to my earpiece... so technically it should be the same case for phone? I hope there's a way...
