alsa-project/alsa-ucm-conf issue #171 was opened from joakim-tjernlund: Noted that speakers are silent and not sure when that happened. I note that pavucontrol shows sound playing on HDMI / Display port 2 (which is unplugged) when I test audio in MATE volume control. It seems that HDMI now is default even though it is unplugged ?
