While the device works right in principle, every time an app closes the device, it mutes itself (or crash, this may be a Hw problem). There is no indication of the broken state in the mixer displays of alsamixer or alsamixer-gui, and amixer output does not indicate any change, either (see below).

Oh, and to fix it, I can just mute-unmute ("cycle") the device "PCM 1" (no levels, just a switch).
