Created attachment 60009 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
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: [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:
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 003 Device 003: ID 0763:2007 Midiman M-Audio Sonica Theater
(lsusb-v I will attach as well).
