I woke up this morning and noticed my pc had locked up. I restarted, and didn't notice any problems. Later, I tried to watch a video and could just barely hear the sound after turning the speaker volume all the way to the max. I checked the device settings, windows volume control, etc. Nothing had changed there, didn't show any problems either. I tried updating the driver, and then I had no sound at all. I reinstalled the old driver, and you could just barely hear it again. I've tried it on different audio and video files, all with the same result. The pc is running Media Center 2005, soundcard is an Audigy 2 ZS. I installed a new dvd burner the other day, but this is the first I noticed any problem. I checked my cables again, and everything appears to be correct. Any ideas?
