[USB-Audio - USB Device 0x46d:0x81a, recording] Device shows up in the mixer's "hardware" tab, but its input is not in the "input" tab

[Riccardo Pelizzi]

When i plug in this webcam (Logictech C260), alsa detects it properly and it shows up as a second device in alsamixer with one input. It also shows up in the "hardware" tab of the gnome mixer, but in the "input" tab only the input from my HDA intel is shown.
It looks like a pulseaudio issue to me, because it's not in pavucontrol either... and this is after pulseaudio failed to detect *any* device (input and output), but i already rebooted and forgot to collect information for that bug report :-/

Rebooting solved the problem, but it's not the first time I have this random failure...

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.
