With the amount of experimentation I've done in the past couple of days
it's hard to figure out what information is relevant. I'll try to boil
it down:
I couldn't get btsco to work, though a2play did.
With pcm_a2dpd I get occasional (~one every two minutes) chirps out of
the headphones, mainly when interrupting ogg123 (aplay, whatever).
hcidump -X -V shows no traffic except briefly when those chirps occur.
Sound is fine through the alsa redirect.
With pcm_a2dpd2 I have jumpy, very sped up sound from the headphones and
plenty of traffic through hcidump. Alsa redirect sounds about the same
as the headphones, but the daemon gives the following errors:
A2DPD[21:11:15.563]: alsa_transfer_raw: (errno=32:Broken pipe)EPIPE(-32)
A2DPD[21:11:15.983]: append_to_ring_buffer: Ring buffer is full
A2DPD[21:11:15.983]: append_to_ring_buffer: Ring buffer is full
A2DPD[21:11:15.986]: append_to_ring_buffer: Ring buffer is full
and on, filling the screen with the full buffer messages.
I suppose that basically describes the situation. The rest is
background. I'm willing to do whatever I can to help, but as my C is
rusty I figure it's time to ask the devs.
~Chris
Background:
I followed the build instructions and troubleshooting for Plugz at
bluetooth-alsa.sf.net. Everything went without a hitch as far as I can see.
I have a pair of Creative CB2530 headphones. I've tried them with four
different bluetooth dongles including both Broadcom and CSR (currently a
DLink DBT-120). There were no differences between dongles. Connecting is
never problematic at all.
This is Gentoo with Bluez 3.9 and kernel 2.6.20 with the sco patches.

I understand you have sound through alsa but not through a2dp, and only occasional chirps? What headset/adapter is it? Did you start hcidump before a2dpd? Make sure to use 44100hz 16bits samples. I need the full a2dpd -g output or enabledebug=1 in a2dprc to help more. Use pcm_a2dpd if it gives good result through alsa.

For example, a2play under btsco basically worked, and if I force the chirps to occur quickly enough (by pausing and unpausing the player's process... each cycle causes a chirp) they merge into music. To my uninformed mind this suggests that plugz might work with the headphones if it would just send the data. So perhaps just to satisfy my own curiosity, why is a2dp not sending any data over bluetooth, as shown through hcidump? Is it waiting for some sort of acknowledgment from the headset? And what's the status of a2dpd versus a2dpd2? ~Chris ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.

What's the difference between using > pcm_a2dpd2 and the "alsa redirect"? I didn't catch what "same as the > headphones" was referring to either. In retrospect I think I wasn't clear about pcm_a2dpd and pcm_a2dpd2. By those I meant the alsa plugins (libasound_module_pcm_a2dpd[2].so) as opposed to the similarly named daemon and NOT a definition in my .asoundrc. The "alsa redirect" meant setting enableredirectalsa=1 in .a2dprc. I gather that this causes the a2dpd system to spit sound back out through alsa to speakers instead of through a bluetooth connection. To restate more clearly (maybe) I'll give you a chart: a2dpd plugin ("type a2dpd" in .asoundrc): bluetooth headphones (enableredirect=0 in .a2dprc): occasional chirps almost no traffic through hcidump flags=1 only gives info upon occurrance of chirps normal computer speakers (enableredirect=1): music sounds fine a2dpd2 plugin ("type a2dpd2"): bluetooth headphones (enableredirect=0): garbled, sped up sound plenty of hcidump traffic flags=1 reports once a second or so normal computer speakers (enableredirect=1): garbled, sped up sound ring buffer full messages spew forth An interesting thing to me is that enableredirect, if it does what I think it does, seems to show a non-bluetooth problem... ~Chris ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
