Hi... we have Via mini ITX running embedded XP SP2 ...

Everything is integrated... network/soundcard etc....

Client called to tell us the sound wasnt working so i dialled in remotely and everything appeared to be running fine... Music was playing... schedules working etc...

He swears black and blue that he didnt have the audiostack/AMPs turned off etc... plugs were all in properly...

So... sounds playing but nothings coming out of the PC... to me says soundcard?? 

Told him to reboot and the sound starting coming out again...

Any Ideas?? why would it cut out randomly then start again on reboot?
