Dear Maintainer,

Recently I installed new updates, including pulseaudio:

2021-10-19 23:32:51 upgrade pulseaudio:i386 14.2-2 15.0+dfsg1-2
2021-10-19 23:47:37 status installed pulseaudio:i386 15.0+dfsg1-2

After these update(s) the internal speaker of the laptop is not going
automatically to mute,
if the headphone is plugged in.

If I enable auto-mute, the internal speaker is going to mute, as wished.

As soon as I remove the headphone-plug,
auto-mute is immediately disabled  at alsamixer.

If I plug-in the headphone again, the internal speaker is not going to
mute, as
wished.

File /usr/share/pulseaudio/alsa-mixer/paths/speaker.conf contains the next
extra lines,
if I compare with version 14.2.2 :

; Make sure the internal speakers are not auto-muted once the system has
speakers
[Element Auto-Mute Mode]
enumeration = select

[Option Auto-Mute Mode:Disabled]
name = analog-output-speaker


If I comment out these lines, auto-mute is not disabled anymore by
pulseaudio,
and Auto-Mute works as designed.

Probably this "fix" is coming from
https://gitlab.freedesktop.org/pulseaudio/pulseaudio/-/merge_requests/433/diffs?commit_id=19e34d8d5bb9380ed70607b3f661c26df6d4836c

.
  It is a strange "fix" . because it completely destroys the
functionality of
Auto-Mute.

I reported about almost the same problem at Bullseye Testing at February
2021
with
bug https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=981572
<https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=981572> .


My laptop is a simple DELL D620, without any additional audiocard.
If the internal speakers can not become  mute independent of the headphone
it cannot be used anymore at video-conference and at a shared office.
