[details=Hardware information]Now that my system is booting again (as resolved over here), my audio is messed up. In a nut shell, there is this persistent static sound that lasts for a second or so after playback ends. I didn’t notice this before, and the weird burbling sound on the front track is there during playback. The front track is barely audible. I also found that it appears to be operating in mono mode (tested this with the left speaker/right speaker sound test). Another thing that I discovered is that the sound card listed keeps resetting to the nVidia card, instead of my built-in audio card. So, I’m wondering if this might be connected. I’m thinking ideally, if I can permanently disable the nVidia audio device, my system might return to working again. I tried blacklisting the driver, but that only completely disabled my audio, which is less than ideal.
Help would be greatly appreciated.
