I have a pc running Vista sp2 and I don’t like to reboot very often, but occasionally I have to restart the Windows Audio Service because the sound just doesn’t work any more. I am using the onboard audio.
Any ideas why?
I’ve had a similar problem, described by Rafael Rivera here. I fixed the problem by installing newer drivers for my onboard audio chipset; try checking if you have the most up-to-date drivers (maybe check the manufacturer homepage). At least the link will better explain what is probably happening.
