Subject: [IRLP] Found an interesting problem with mixers changing settings
Starting in Debian 10, the alsa-utils package in Debian launches a daemon that is designed to capture mixer settings and save them periodically. While this sounds like a great idea, it can sometimes overwrite your mixer.
This is started with a systemctl service, BUT, using the normal "disable" features seems to not work. It is a bug, but it has never been fixed. To make it so this daemon does not start, you need to mask the service so it won't start:
systemctl mask alsa-state
systemctl mask alsa-store
systemctl mask alsa-restore
This will prevent the mixer from saving on reboot, and allow the controls that IRLP uses to control the mixer properly.
