bluetooth a2dp hiss with bitpool=53

[wwwes]

I've searched here for hours and haven't found a fix for this. Unlike many of the posts I've found and read here, I don't have any issues with skipping with my bluetooth earbuds.
On my 8525 with 53 decimal set for bitpool and max bitpool and jointstereo=0 I get tinny hissing artifacts. not worth using.
these are no-name earbuds similar to the itech clip ones. don't know who made em-came from ebay. they worked great with my widcomm stack harrier.

increasing the bitpool numbers further has no effect on these. they don't seem to skip at all though. am I missing another reg setting change?

are there off the shelf headphones that don't skip without the a2dpfix service and work well with hermes? I see mixed answers on many of them.

just when I think this phone is pretty stable it locked up this morning and didn't alarm. I overslept...

I'm also having same annoying hiss issue, afaik only another bt stack (namely widcomm) or maybe new aku update would solve this problem.

don't know where they are going with porting widcomm to hermes,
but hope they have some progress...

Hacks, registry tweaks section of Wiki, search "A2DP" or "stereo". I use sony-ericsson hbh-ds970's and after the tweak, sound as good as my old wired earbuds. Only shortcoming is the occasional sound drop (millisecond or two, but still annoying). Setting PocketPlayer priority to "normal" virtually eliminates the problem. An extreme solution is applying Sleuth's A2DP fix... search the wiki for more details.

You mean skipping issue rather than hissing sound issue ?

The hiss is a known artifact of the M$ BT stack. My testing with the Widcomm stack eliminated this issue. However, out of the box version 1 Widcomm tests showed decreased fidelity and noticable buzzing on the high end. However, I believe there's a number of A2DP fidelity tweaks that can be applied to correct this. I will start working on this when superdave gets the handsfree issue solved .
