Title:
[System76 Bonobo Pro, Realtek ALC892, jack sensing] Alsa does not mute
speakers when headphones are plugged
Status in alsa-driver package in Ubuntu:
Incomplete
Bug description:
When plugging in headphones, the headphone sense happens properly, and
most speaker output is muted (Surround, Center, LFE), but the Front
speakers are still at regular volume. Muting the Front speakers also
mutes the Master, and sound stops to both headphone and speakers. a
workaround is to set Front to 0 after plugging the speakers with the
following command: /usr/bin/amixer -c 0 set 'Front' 0
This is a new development brought on by a recent update. Sound used
to work properly.
