Public bug reported:
I have a laptop Dell Inspirion 5391 that was shipped with Ubuntu 18.04,
and it doesn't have such problems. But I have manually installed Xubuntu
20.04 LTS (firstly because I need full disk encryption with LUKS). And I
have two problems the with sound system:
1) If I plug headphones, there is no sound. Sound becomes only if I
manually switch source port to "Headset Mono microphone" from
"Headphones stereo microphone" in pavucontrol or with the command:
pacmd set-source-port 4 "[In] Headset"
or with ALSA:
amixer set 'Input Source' 'Headset Mic'
I have a workaround with /etc/acpi/events, but it is not seamless (I
have an one second delay when I plug the headphones).
2) There is no separate volume levels for speaker and headphone in
pulseaudio.
