[Bluez-users] headset playback problem suse 10.0

[Bluez-users] headset playback problem suse 10.0

[Edgar Neukirchner]

Hi!

I have installed and configured bluetooth-alsa without getting any errors. But 
when trying to play a test.wav file with aplay, there was no sound at all - 
only a slight increase of the noise floor in the headset (Jabra BT330). 
Obviously there was some communication going between bluetooth dongle and 
headset, as the blinking frequency of the LED on the headset changed.

When I issued the command cat test.wav > /dev/dsp1 as root there was an output 
error message in the terminal and in the logfile the following:

 kernel: ALSA sound/core/pcm_lib.c:2126: playback write error (DMA or IRQ 
trouble?)
kernel: ALSA sound/core/pcm_native.c:1451: playback drain error (DMA or IRQ 
trouble?)

I use the latest snd_bt_sco module from cvs with suse 10.0 and kernel 
2.6.13-15.8-default. Headset is Jabra BT330, bluetooth usb dongle is 
CCBT2035BDGP23-2 from Broadcom

Who can help?

Thanks,
Edgar

Are you trying it with the experimental kernel patch on
http://bluetooth-alsa.sf.net for broadcom adapters?

...I tried it out, but no success - same as before.
