Solve : Sound Goes Out Until Reboot?

1.	Solve : Sound Goes Out Until Reboot?
Answer» I just set up a multimedia system for a BUDDY with the PC (new gateway, can't remember model #, DX something) connected to flatscreen tv via HDMI CABLE using a Hauppauge HVR-850 TV tuner (USB) for tv signal and Windows MEDIA Center as main tool for TV/DVR ETC. However, he's having a problem. He says after watching a show for a little while, all of a sudden the sound stops completely and he has to reboot to GET it back. This is very weird to me that it's intermittent. I can figure out when sound is not working completely, but this is foreign to me. Any ideas? Thanks.
