Posted this onto other sites FYI I've installed Windows 8 onto a computer, the sound worked nicely for one day, but after a restart it no longer works. Checking shows that the drivers are all installed and it can detect the speakers, but yet no sound comes out of them. Anybody have this issue? I've looked and I've noticed that the speakers on the same machine work for my Linux dual boot, so the issue is something to do with Windows, the hardware by itself is also working fine and everything is plugged in. There simply is no play back, I've attempted to reinstall the drivers and I still can't get anything. Can anyone help here?
