Ok, this one is really confusing. I unplugged my machine and moved it. When I plugged it back in everything booted ok, Game plays but no sound. Went into the system bios and checked to make sure audio was enabled, then checked alsamixer to make sure levels were turned up. Everything checked out ok but, still no sound. Grabbed an old set of powered computer speakers and plugged them into the audio out from the Motherboard. Sound was back. Ok, must be in the old audio amp. Ordered a new nucore amp. Installed it today. No sound. Still get sound with the computer speakers, what am I missing?
