I have a Dell XPS 8900 running Windows 10 (64-bit). I recently reinstalled Windows due to a BSOD issue with several boot files (I would get a BSOD whenever I woke the computer from hibernation), which has now been fixed.

However, I'm now having a very perplexing problem with my audio:

1. I hear sounds from Google Chrome and the Windows system.

2. I don't hear sounds from any other programs (notably VLC Media Player and Windows Media Player, even games). Both of those programs open and say they're playing music, but they don't even appear in the volume mixer.

3. Both the Windows Audio and Windows Audio Endpoint Builder are running, and restarting them has no effect. (Even though the sound troubleshooter suggests that the problem is with one of them.)

4. I have reinstalled the audio driver from Dell's website, and it had no effect.

5. I also updated the chipset, which had no effect.

6. I have switched to the generic Windows audio driver, which got rid of ALL sound.

7. There are no changes when I plug in headphones: sound still only comes from Chrome and the Windows system.

I'm at my wit's end. Any suggestions?
