Pulseaudio disabling auto-mute mode

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/Pu … -Mute_Mode and https://wiki.archlinux.org/index.php/Ad … 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?)

Re: Pulseaudio disabling auto-mute mode

You could try to remove/comment

load-module module-switch-on-port-available

in your /etc/pulse/default.pa that should stop pulse from reacting and changing the profile on a jack event. I have seldom seen that actively disable the auto-mute mode though so you might have some weird profile definitions, what's your outputs for

pacmd list-cards
pacmd list-sinks

?

Re: Pulseaudio disabling auto-mute mode

BTW, doesn't look like removing "load-module module-switch-on-port-available" made any difference.

Re: Pulseaudio disabling auto-mute mode

Hmmm, seems like removing "load-module module-udev-detect" prevents the disable-auto-mute behavior.  Not sure why ...

Re: Pulseaudio disabling auto-mute mode

You are using a sof/hda chip so that gets reconfigured according to ucm information present in /usr/share/alsa/ucm2/ ... which currently seems to be in a buggy state, general betterment in this regard can be expected on the next alsa-lib/pulse releases.

As you are manually loading a sink already anyway you could continue like that, if you still need udev-detect for other devices check if loading it with use_ucm=0 is sufficient to not trigger the changing behaviour.
