Bluetooth out of sync with audio?

Hello. I have a Desire HD with android 2.2.1.
Last year I had a HTC Touch HD with windows mobile. I bought a chinese copy of the jabra bt3030. The sound was out of sync with any video I could play. I didn't try with other phones, anyway I didn't spend that much for the headset, so I just sold it on ebay....thinking that that's why people don't buy chinese copies. OR maybe it was a problem of the transmitter of the Touch HD...so I didn't buy anything else and stayed with the normal wired earphones instead of having another stereo bluetooth headset.
NOW
I have the Desire HD, and bought THE ORIGINAL jabra BT3030. EXACTLY the same problem: youtube, trailers from MDB, .avi TV-rips played with rockplayer ---- EVERYTHING has this horrible out-of-sync audio which makes it impossible to watch even 5 second of a video without getting crazy.
I mean is that a problem of every stereo headset? IS that too much information to be sent to the headset? What can I do to make the sound sync with the video?
I have a stock rom.
Does anyone have this kind of problem? With which phone? With which headset? Is there any support forum for the Jabra BT3030 (it is the dog-tag one) ?
Last time it was a cheap 20$ chinese copy....this time is a retail 65$ boxed jabra....and I EXPECT it to work properly...

maybe you can set up the connection as new. or reset to factory settings

what do you mean by 'set as new' ? I paired the devices today for the first time. Reset to factory settings...is something i would rather not do

BT connections have a small delay.
You can try to set some BT settings to create a smaller buffer or something...

for instance? which BT settings could I adjust?
About the delay: i used until now a normal mono bluetooth headset, which is not A2DP so cannot reproduce media content (music or games sound and so on). There is a paid app on the market called BT Switch. This app redirects every sound of the phone to the mono bluetooth headset, allowing you to listen to music, hear the GPS directions, watch a video on youtube with the sound on the mono headset and so on.....well, there isn't any delay. That's why i can't understand why the stereo headset has so much delay....ok, it is stereo, more informations to send and so on...but the mono one has NO delay at all.
But of course a stereo solution with good earphones is much better than a mono with the low quality sound of every mono headset, which are built only to use the phone and not reproduce any kind of media sound...

Bluetooth Audio One Sided

When I connect to media audio via bluetooth in my car, I can only get audio out of the left side speakers. This is repeatable on different apps that play music. When I play a radio station in my car I get sound out of both sides.
What can I check to help diagnose this problem and hopefully fix it?
Thanks.

Does anybody else have this problem?

Does your car audio system support A2DP stereo Bluetooth profile ? Probably it does, otherwise I don’t think you can stream audio with just the Hands-free (HFP) profile (which is a low quality link meant only for calls). Mine works fine in stereo with my car’s audio system. Try deleting all the BT settings from your car and initialize everything from the beginning.

Iam verry sure that your audio car not support A2DP because in my car i can use for stereo...try to see the specification for your car audio bluetooth..

It works fine when I use my Galaxy Nexus. This makes me believe it supports A2DP. This problem is unique to the One X for me. Did I get a bad phone?
Also, when I crank the balance over to the side that doesn't work I can hear it a little bit, but it's crackly and distorted.
EDIT: Problem solved. Re-seated the wiring in the sound system and everything is fine now.

[Q] Possible to route audio through A2DP and the phone's speaker simultaneously?

The subject says it all. Can I route audio through Bluetooth A2DP and the phone's speaker simultaneously? I want to keep my phone connected to my car's audio system via Bluetooth voice and A2DP. But sometimes I want to switch to XM Radio or other sources. When I do that of course, I lose audio prompts from Google Navigation.
Is this possible?

I'm looking for the same thing. I can get audio through Bluetooth and have notifications go to speaker at the same time, but I can't get other media to go to speaker at the same time.

I would also be satisfied with a widget that lets me toggle the A2DP status of the Bluetooth connection on and off. It would not be the end of the world if I needed to toggle the A2DP off when I switch to another radio source and toggle back on when I go back to Bluetooth as the source in the car.

If you ask me I'd say it's possible.Whenever my phone is connected to my stereo through A2DP, the music is played through loudspeakers only by default. However, when there's an incoming call and my ringtone is being played I can hear it through loudspeakers AND the phone speaker, which creates a pretty cool surround effect. I'd really love to make my music player interact with all the speakers like this all the time. I took my chance installing various apps like SoundAbout to help me figure it out, all to no avail. Any ideas?

Bluetooth audio

Im having an issue with audio quality on bluetooth audio music , on any touchwiz rom it sounds compressed and awful the only rom i found it sounded good on was cm10 but i missed the functionality of spen. Both roms were ran on same bluetooth soundbar.
So my question is have any of you noticed the bluetooth audio quality or is it something on my end, if you have are there any solutions to improve the audio quality.

I am running JediX11 and i use PowerAmp music player. It sounds great and has a 10 band EQ If you try it o don't recommend using the "stereo x" setting it adds more of that compressed audio sound. I use Bluetooth to connect to my car stereo and a portable speaker set i have. I can tell no distinct difference between the BT audio and the headphone jack. I also uninstalled beats audio, Its just another layer of equalization software that can really degrade sound quality (i tried every possible setting before i removed it).

anyone play music in their car with this and have it NOT suck?

Wondering if there's a secret. It's like everything below 200mhz has been removed, both through headphone jack and bluetooth.

Sound quality for me both on Bluetooth and headphones is great

Sounds good to me

Same here. Good quality in car whether i use my bt adapter or through audio jack.

Using Vanilla Player to play local mp3s sounds good on my headphones. Maybe a little "small" on my BT speaker, but its a small cheap speaker. Haven't noticed poor quality in my car.

I do use bluetooth pretty much exclusively in the car. I have a pair of headphones that sound really good with the phone. Dont use anything else to play music but I do sometimes have problems with the headphone jack when I move the cable around.

The sound quality when connected via cable to my car stereo or headphones seems to be fairly decent, though a bit noisier than the audio I get from my iPhone. I still have the problem of losing audio on calls after disconnecting from the audio jack (I can't hear callers on incoming calls and sometimes callers cannot hear me when I call them) and then having audio not re-routed back to the audio jack the next time I connect. Because this has happened on more than one Fire phone, I just use a cheap Bluetooth USB adapter connected to my stereo which does degrade the audio quality somewhat however.

Do you guys use any sound processing apps at all? I seriously have no bass coming out of my phone. I turn the bass up almost all the way on my car stereo, and in an EQ app for the phone (tried without the app too), and it's still not quite what a normal mp3 playing directly on my car receiver sounds like.
I'm on fire OS, are any of you on cm11?
Also this uses dolby or something doesn't it? I worry that something I've disabled has messed it up, but don't know what it would be.

No sound processing apps for me. I'm usually on Fire OS 4.6.3 rooted with no Google Play services. Now I'm on 4.6.5 unrooted (trying to resolve a GPS issue) and it sounds the same over BT.

Works fine for me too. Hardwired through AUX or with Bluetooth. Headphones/earbuds sound good too. I mainly use Amazon Music player, Google Music, and Pandora.

I've had no problems with BT connection from my Fire OS Fire Phone to my Sony receiver. Bass response is good whether or not I am running "Equalizer FX." I use Equalizer FX because the bass on the car stereo (and my headphones) rolls off below 60Hz.
I have learned from other phones that running the volume at max level can cause clipping and sound degredation.
