No audio devices

If all your sound devices disappear on Ubuntu (especially after upgrading the kernel), then run this:

: sudo apt-get install linux-modules-extra-`uname -r`

Static

On Linux at random times I get static from any audio playback. It's exactly the symptoms here: https://askubuntu.com/questions/1066565/static-noise-when-playing-sound (staticy, random, lingers). The fix is pulseaudio -k.

No dialog

Sometimes in a movie via parole the dialog disappears or is very quiet, even though the music is normal. Or with mpv it happens right from the start. This gets it back:

: mpv --af=lavfi="loudnorm=I=-16" the-movie-file
