I often switch between my headphones and my speakers and here is the usual behavior supposed:
- If I unplug my headphones connected to the front panel, the audio output will automatically switch to the speakers connected to the rear panel.
- If I reconnect my headphones on the front panel, the speakers connected to the rear panel will automatically turn off and the sound will play. The volume profile will also change.
I think these are the default settings because I have no problem with 2 other computers with almost the same setups.
This problem occurred after suspending my computer, which is probably not due to a system update.
What is happening now is:
- Unplugging everything connected to my front panel will not mute my computer.
- The only way to make my headphones work is to change output
device to "headset" in Pulseaudio volume control. Even if she
as unplugged, I always get an audio output. This
has been tested with different devices.
Then I would receive an audio output of both my speakers and my headphones. The automatic mute option in alsamixer does nothing. I've tried using the gnome version and it pulls a
** (gnome-alsamixer: 12461): WARNING **: gam_toggle_set_state (). No idea what to do for the mixing element "Auto mute mode"!
Fault. I tried to restart, reinstall Alsa and Pulseaudio, but the problem persisted.
