Audio devices vanish.

[Lars Noodén]

I did an update yesterday and when I booted today, pulseaudio volume
control (nor any other apps) could not find any USB devices  They worked
fine yesterday before the update.  Now it cannot find any of them, not
even the headset I usually use.  Where should I start with solving this
or documenting the bug?

When I go to  pulseaudio volume control neither the tab for input
devices nor the tab for output devices show anything.  They used to show
whatever I had plugged in.  I've tried doing another update and
rebooting (superstition there) and I've tried reseating the USB devices.
 No avail.
