[Solved] How to restart ALSA?

Hello,

How do I restart ALSA?

Restarting ALSA is a required step in https://wiki.archlinux.org/index.php/Ad … DIF_output

sudo /etc/rc.d/alsa restart doesn't work of course.

I exprected it to be doable via systemctl but alas:

$ sudo systemctl restart alsa
Failed to issue method call: Unit alsa.service failed to load: No such file or directory.

After editing /var/lib/alsa/asound.state, run:

alsactl restore

Which will read that file. Also need to "close" the soundcard, which means:

$ cat /proc/asound/card0/pcm0p/sub0/hw_params
closed

This was presumably done by the alsa initscript in Gentoo, when that wiki entry was written.
