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
