I'm not sure how/why (or when it started) but pulseaudio is disabling
auto-mute mode on my laptop. Normally when you plug in headphones,
speakers get muted. However, every time PA starts up, it disables that
auto-mute feature. (I then have to go into alsamixer and manually
re-enable it.) Not a huge issue, but definitely a nuisance.
It's definitely PA that's responsible: if I enable auto-mute, then do
"pulseaudio --kill", the setting immediately gets disabled. I've
followed the instructions at
https://wiki.archlinux.org/index.php/PulseAudio/Troubleshooting#Auto-Mute_Mode
and
https://wiki.archlinux.org/index.php/Advanced_Linux_Sound_Architecture#Disabling_auto_mute_on_startup
- i.e., change the setting to enabled, and then alsactl store. However,
that's obviously having no impact, since pulseaudio later *overrides*
the alsa setting when it starts up.
Anyone else having similar issue? Or have any idea what the issue is /
how to fix? (Or link to an open bug report?)
Thanks,
DR
