Lost Sound when Plugging in USB flash

I was playing an .avi in kaffeine, and at the same time I plugged in a 512MB USB flash drive. Immediately I lost sound in Kaffeine, though video was still playing. I check Youtube via Firefox, same thing.

I used to have a problem in Amarok where if Amarok crashed, it would mute the sound without my noticing. Thankfully I remembered to check this in Kaffeine, but that was not the problem.

I don't mess with the sound settings often, so I had a fun time trying to find them (turns out they're not in your system or settings menu... try looking for KMix in the Multimedia menu instead.)

I log on to the freenode IRC channel #kubuntu, and a couple nice folks there had some suggestions for me.

I was told to pay special attention to KMix lines: master, master mono, PCM. These were all fine (at or near the top).

(You can also open alsamixer via the command line)
I was then advised to restart ALSA.
sudo /etc/init.d/alsa-utils restart
This did not work. I tried closing all my programs which might be using sound, and running the command again. This did not work either.

I ran the command, and then rebooted. This works! Now I have my sound back.

In my experiences, any multimedia program does not interact well with plug'n'play peripherals, be they flash drives or mice, etc.

Whenever I dj, I make sure to plug in all my external devices before loading the music software.
