So my PC suddenly stopped playing sounds from my speaker. I tried reinstalling NVIDIA audio drivers and that failed. I then did a fresh windows installation, and still nothing. I know when I built this PC, I tried finding one of the cheapest motherboards that I could find: AsRock 970 Extreme3 R2.0. The PC does not have a dedicated sound card, and so I was thinking that the integrated sound card on the motherboard could be dead. Does anyone agree with that statement? Is there anyway I can confirm that? Are there any other steps or recommendations to fixing the PC before buying something? Thanks.
