The A2DP LAG ISSUE UNIVERAL FIX *CLICK FOR THE FIX*

[Mikee4fun]

On a universal or any other hacked device with a2dp you need to go into the registry and add this dword string into the following location. HKEY_LOCAL_MACHINE\Drivers\BuiltIn\BtA2dpSnd

Make a new Dword value and name is Priority256 and then for the DWORD Data value make that 60 save and reboot. Presto no more lag, cuts or audio drop outs. I have attached the modified registry key for ease. To manually mod it the registry location is at the following.

HKEY_LOCAL_MACHINE\Drivers\BuiltIn\BtA2dpSnd

Update: If you run wisbar advanced you need to manually launch it. If you have it start up at boot it will cause lagging issues as well. So just disable wisbar advanced from startup and you are cookin.

Well done!

P.s. 60 in HEX or Decimal?

also.. I do not see the Priority256 registry key entered in the .Reg file you uploaded. (?)

[Mikee4fun]

Its in decimal and you have to login to see it.

What I meant is that the contents of the .Reg file within the .Rar file attached are as follows :

[ H K E Y _ L O C A L _ M A C H I N E \ D r i v e r s \ B u i l t I n \ B t A 2 d p S n d ]

" F l a g s " = d w o r d : 0 0 0 1 0 0 0 2

" I n d e x " = d w o r d : 0 0 0 0 0 0 0 8

" O r d e r " = d w o r d : 0 0 0 0 0 0 0 8

" P r e f i x " = " W A V "

" D l l " = " b t a 2 d p . d l l "

---

they don't seem to contain the magic Priority256 key.

My apologies for not explaining properly.

There is too simple to be truth.
Does not work on Wizard 2.8.7.1 WWE

I found that re encoding things into WMA 9 fixed a lot of problems too. I use a2dp on my Magician a lot so I'll know if it works =P

EDIT:

That key wasn't there before I applied the reg fix. Also, I do not have a file called bta2dp.dll on my Magician.

Do you know what you're doing? ;D

[Mikee4fun]

This has been done on a universal running the Qtek 1.30.77 rom. So possibly there are different bluetooth radios between the universal, wizard, magician

Hey... do any of you guys want to grab a couple of .dll files from your phone and post them? I've tried extracting them from ROMs, but they're always corrupt... I need:

bta2dp.dll
and
Avrcp_MPplugin.dll

I'm not sure if the builtin file manager will let you just copy them out though, so you may have to get creative... Thanks!

Mikee4fun,
Thanks for this. I upgraded my JasJar to the Qtek ROM and just got a set of BT headphones that support both a2dp and AVRCP (it's the GlobalSat Wireless Entertainment Package - Bluetooth Headset and Transmitter (BTH-820 plus BTA-830)).

When I paired the headset with my JasJar, the playback was all screwed up! I applied your hack and now it works beautifully. AVRCP is working great too. Thanks for your help.

Thanks

Works on my QTEK 9000 and iPhono mini 450Rx nicely otherwise I'm getting this split-second lag periodically upon playing song
