Every time I restarted Fedora the volume would reset to 50% and the mic would be de-selected as the recording source, so VoIP wouldn’t work. I’d have to manually reset these every time I rebooted. Turns out, as with everything Linux, there’s a simple solution! 😉
You set your desired volume, login as root, then run `alsactl store`. Or line by line (set your desired volume first)…
$ su -
# alsactl store
I should also say, I haven’t actually rebooted yet, so I’m just hoping this will work, it’s as-yet-untested!
