Hi all,
i would love to get my new Bluetooth headset (Bluetake BT420) running
with linux. So i compiled and installed the alsa-bluetooth cvs code
(btw: i had to add "-lsdp" to the libs in the Makefile to make it
compile).
I can load the kernel module and start btsco:
/usr/local/bin/btsco 00:08:F4:30:03:71
Device is 1:0
Voice setting: 0x0060
RFCOMM channel 5 connected
But when i play a wav-file via aplay or play/dsp1, i do not hear
anything but get an error message in the system log:
Nov 25 00:12:34 linux kernel: snd-bt-sco: playback_open
Nov 25 00:12:34 linux kernel: snd-bt-sco: prepare ok bps: 16000 size:
16002 count: 4000
Nov 25 00:12:34 linux kernel: snd-bt-sco: playback_trigger 1
Nov 25 00:12:34 linux kernel: snd-bt-sco: setting playback to bspcm
Nov 25 00:12:44 linux kernel: ALSA sound/core/pcm_native.c:1316:
playback drain error (DMA or IRQ trouble?)
Nov 25 00:12:44 linux kernel: snd-bt-sco: playback_trigger 0
Nov 25 00:12:44 linux kernel: snd-bt-sco: setting playback to NULL
I am using kernel 2.6.5 from SuSE-linux, so i replaced the kalloc()
statements with the old ones (found in cvs and did some merging).
Compiled and loaded fine without any errors.
Do you have an idea whats going wrong? Or doesnt it work with 2.6.5
anymore at all?
Thanks!
Sebastian

Sebastian,
I'll second Marcel's suggestion you try a newer kernel. Maybe you
already have...
It's unfortunate that the module api is changing across *stable*
versions of the kernel. The reality is we don't have the volunteers
required to maintain for multiple kernels.

maybe you should update to the latest bluez-libs.

Why don't you try a 2.6.10-rc2-bk9 or 2.6.9-mh4 and see if this one
works.
