ALSA Restart

ALSA failed this evening. Fixed it this way:

1. lsof | grep pcm
2. kill -9 any processes returned
3. restarted ALSA: sudo /etc/init.d/alsa-utils restart
4. Didn't work--quit Firefox, then ps -ef | grep firefox
5. kill -9 the firefox process
6. restarted ALSA: sudo /etc/init.d/alsa-utils restart
7. Sound returns--yippee
