Anyone having any hoster glitches?

[Azkaraoke4]

I have been expiencing little glitches and i'm trying to figure this out. I thought I would throw this out to see if anyone else is having similar problems, or if anyone knows how to fix it. I am leaning towards thinking it is a sound card problem. I have been having a couple of problems and they are this. During a show the music (sound) will just stop. no sound. The graphics will still be moving right along on the screen but no sound. So I have to press stop on the song and then 80% of the time I can press play and it will be working again. However sometimes I will press play and my playlist will read error down the playlist for every song. Then I reboot and it still reads error, so then I opened a new playlist and tried to play a song and it said error. The only way I could fix that during that show is to completely unplug the computer from all power. Then I rebooted and it worked. The reason I think it is a sound card issue is because I formatted one of my systems yesterday and I loaded everything, pulled up hoster and went to play a song and it said error for all the songs. Then I realized I had no sound drivers loaded, because i turned off the onboard sound but didn't put in my audigy drivers. So I loaded them and no errors. The other problem I am having is that hoster will just freeze! I will try a ctrl, alt, del to close it and it won't even close that way. The only thing i can do is shut down to get it back up. The audio problem I am only having on one system, but the freezing up problem I am having is on two systems. Anyway if anyone knows anything I would appreciate the info. I did think the harware acceleration thing was fixed and hadn't changed it and didn't have any problems with 2.217. However these all started happening with 2.219 so I have since lowered the hardware acceleration. Is there another 24 bit sound card mtu recommends besides audigy? Ok thanks everyone.
