This probably won't make any sense, but for some reason I had good clear
sound for a few minutes today.  Since I've been working on other things
and audio is a luxury for me I haven't been trying to get it to work
lately.  However, this afternoon I plugged in the speaker and tried a
wave file and it played great.  Then, since the machine has been running
a for a while and I've done updates recently, I rebooted to have a clean
start.  I though it might get rid of the bouncing vertical scrollbar,
but that's another issue.  I was all set to play music and videos, but
after the reboot the audio wasn't working anymore.  Something somewhere
got the audio working only for it to stop after a reboot.  I checked
alsasound and it's running.  Any ideas?

Thanks
