While VLC was playing video with sound via ALSA, I have disconnected an USB hard drive (after I have unmounted the file system). Then the sound stopped working while VLC was still playing video.

The USB-LED on the device was blinking green (error condition), while normally it lights red when the device is ready to use.

Also the pulseaudio system which uses the UA-101 via ALSA was hanging.
I had do turn the UA-101 off to stop pulseaudio hanging and let apport-bug continue to finish creating the bug report.
apport-bug then suggested the bug title "UA-101 - UA-101, playback Pulseaudio fails to detect card", but this is not the bug to be reported here.
Note: Such a bug in pulseaudio exists: see https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/986817 for that issue.

The bug to be reported here is that the USB connection to the UA-101 got out of sync, because another device has been disconnected.
This seems to be an issue with ALSA and USB.
