[USB-Audio - Logitech BRIO, recording] fails on suspend/resume

[Rhett Aultman]

My Logitech BRIO webcam's mic doesn't pass audio after suspend/resume cycles on my desktop. The ALSA interfaces are present and the mic devices appear in pulseaudio and the Ubuntu audio settings applet, but no audio is seen via arecord or the volume meter in the audio settings applet.

It doesn't happen on every suspend/resume and I'm trying to establish the pattern. I think it may be that this happens only on suspend/resume where a handle to the mic was left open. For example, it took 3 suspend/resume cycles to generate this error report, and the one that finally reproed the issue was the one where I left the mic selection panel of the audio settings panel open. I think the open handle to the mic to supply the volume meter may have been what broke it.

Suspend/resume with no obviously open mic handle still reproed this issue a few hours later. May not be related to suspend/resume with open mic handle as previously stated.
