pulseaudio -vvvvv log of starting pulseaudio, plugging in Sonica Theater and
unplugging it
When I plug in the USB Sonica Theater and Pulseaudio recognized instead of the
bailing out with "usb_set_interface failed" message I get the following
situation regarding volume acording to alsamixer:
- left channel: 0
- right channel: 79
Expected results:
Both channels at 79 or something like that.
I reported this on Pulseaudio mailing list already:
[pulseaudio-discuss] usb sound card: PCM has 8 channels, thats too much &
cannot submit datapipe for urb 0
I think its due to:
> Nov 19 21:47:05 merkaba pulseaudio[1666]: [pulseaudio] alsa-mixer.c:
> Volume element PCM has 8 channels. That's too much! I can't handle
> that! Nov 19 21:47:05 merkaba kernel: [ 53.498439] cannot submit
> datapipe for urb 0, error -28: not enough bandwidth
As Tanu Kaskinen requested I now did a pulseaudio -vvvvv log that I will
attach.
The sound card involved is:
