Errors: Alsa, dmix, unable to open slave
If you’re getting error messages like this
ALSA lib pcm_dmix.c:864:(snd_pcm_dmix_open) unable to open slave
when you try to run Firefox in linux, or any other application for that matter, I may have the solution.
There’s plenty of fairly complicated stuff on the internet about that error. None of it helped me. My problem was actually mplayer.
I had it running in the background....
