Since I upgraded from 12.04 to 12.10, my USB sound device is not working anymore. Headphone sound using the sound device integrated in the chipset is still working correct.
This are the two devices:
Code:
c_w@Thomas-Ubuntu:~$ cat /proc/asound/cards

HDA Intel at 0xeea20000 irq 48

The USB device is the last line in the lsusb output.
If I use the aplay command to play a sound file, the output looks fine, using both sound devices. The only difference is that I don't hear any sound if I use the USB device
In the alsamixer, there is only the PCM mixer for the USB device and this is not muted.
The only further indicator that something is not working with the USB device is that it is marked with a red circle with a line in it in the audio configuration:

Does anyone know what the symbol infront og the USB device means?
I tried to use the trouble shooting guide, but the google docs guide is not dealing with USB devices (right?) and the I performed the steps in the other one, but it is not helping...
edit:
I also tried both 12.04 and 12.10 live CD and it is NOT working with both. But it was working with 12.04, before I upgraded to 12.10.
I also tried the USB device with Windows 7 to check if it might be broken, but it's still working there.
I have no clue what's wrong...
