New computer build, and we are testing the sound off of the GA-X58A-UDR motherboard. Using Logitech G35 headphones, we tried to listen to a video on youtube. The video / sound started just fine. About a minute into the video, the sound stopped working. Since then, we have not been able to get any sound out of the headphones, nor out of a set of speakers hooked into the computer. All drivers are up to date.
Any suggestions on what I should check next?
