Sound went out and song timer stopped.

[bryant]

Last night, about 2-1/2 hours into the show, the sound went silent, and the song countdown timer stopped, but the words kept moving on the screen. Another program was running in the background (Virtual DJ). We stopped the song and tried to play a song with VDJ, and there was no sound there either. Then we closed both programs, and reopened only Hoster, not bringing VDJ back up. Everything was fine for about three songs, and the same occurence happened; 1)sound went silent and 2)song timer stopped, but words kept flashing by. We then shut down hoster, brought it back on, everything was fine for the last hour of the show.

This is on a Shuttle with 2 Gb ram, dual core 2.4, using a usb sound card, XP pro.

Any ideas at all what could cause this?.
