I'm running the Windows 7 RC and sometimes my sound would stop randomly. For example, I would be listening to something, then the sound would suddenly stop. Even while there is no sound, there doesn't seem to be a problem with the drivers. Usually a quick reboot will fix the issue.
I found the same problem here
Has anyone else encountered this issue? If so, is there something I can do to get the sound back without restarting my computer each time?
