Periodically, I seem to loose sound on Vista Media Centre. The only way of fixing this is to reboot my machine.

I have looked at al the sound options and I can see nothing that allows you to fix it without rebooting.

Anybody else out there had this issue?

Details of my beastie as follows:

Intel Quad Core Q6600 2.4G *MB
Coolermaster CPU Cooler
ASUS P5K-E WiFi Motherboard
4GB Memory
Gigabyte RX3855 Radeon HD video card
Hauppauge WinTV PVR500MCE Dual Tuner Card
Hauppauge Nove 500-T DVB-T Dual Tuner Card

I also have MediaPortal running to pickup Freeview, however this issue was around before I loaded this software.

Any help will be appreciated
