Just a few minutes ago my sound was working, and then it stopped! I suspect it was caused by me checking out some video editors. How do I go about troubleshooting this?
What I've so far tried:
- I ran
lsof | grep audioand
lsof | grep deleteto see if there's any process locking the audio path(?), but nothing looks suspect.
- VLC and MPlayer are affected, while Quod Libet (GStreamer) isn't.
[update] Strange one. I don't know if it has anything to do with Quod Libet, but I noticed that after closing (and reopening) it, the problem seemed to disappear. Note that I haven't logged out yet.
