Sorry, looks like I missed your first reply, and catch it in this digest
1. with plugin-rate=44100 and enable flags=1 on head version plugz
	audio playback speed is still not correct, didn't give me the
bandwidth display neither.
	Disable debug output make no difference

2. btsco-0.5 package
	works fine with a2play and plug in, however, both have audio
break 	(play few seconds then stop then play) issue, one thing noticed
is 	that bandwidth display is correct (with flags=1), but seems not
math 	your figure (my is 24525 (191 kbps)

3. head version btsco (checked out from cvs)
	works ok with a2play, plug in play back speed looks ok, but have
audio 	break issue


Thanks/Quinton

[Bluez-devel] a2dpd xmms and hbh-ds970

[Mitja Pufic]

Hello Brad,

I recently got myslef a HBH-DS970 headset and yesterday I tryed it with 
latest CVS version of plugz on FC6. It works great with VLC, but not with 
xmms or a2play. With xmms it is really sped up, I tryed setting it to 
lower frequency but it did not solve the issue, with a2play it is choppy 
and just a little bit faster than it should be. I tryed it with Level 1 
BC4-external and Anycom USB-250 with latest firmware and the resoults are 
the same, it should be some issue with headset. Do you perhaps have 
any idea, where should I look, to fix it for xmms, as it is strange that 
in VLC the sound of mp3s and movies is perfect? Oh and AVRCP in xmms 
works.

best regards,
Mitja

it sounds like a sample rate conversion issue. maybe xmms is expecting
the plugin to handle a rate it can't really do. Fr=E9d=E9ric might have more
ideas.

I use an .asoundrc file which looks like this:
pcm.a2dpd {
	type a2dpd
}

pcm.rs0 {
	type plug
	slave {
		pcm "a2dpd"
		rate 44100
		format S16_LE
		channels 2
	}
}

pcm.!default {
	type plug
	slave.pcm "rs0"
}

Then you can run apps with the aoss utility to get the to use the plugin if =

they don't support alsa enough, and the plugin will only get data at 44,100=
Hz

Strange, as plugz is a newer btsco, I would expect to see flags working.

> 2. btsco-0.5 package
> 3. head version btsco (checked out from cvs)

I suggest you get back to plugz, rewrite the ~/.a2dprc from the cvs and try the tim chick trick.
Any chance another program is using bluez, mouse or whatever?
Last is to post a hcidump -V log?
