Title:
[Sound Output Built in Speaker to HDMI] No auto switch from Speaker to
HDMI and back
Status in alsa-driver package in Ubuntu:
Confirmed
Bug description:
When connecting a HDMI output the Audio Output won't switch
automatically to the HDMI output from the Built in Speakers, it is
required to enter the Settings and switch manually. When disconnecting
the HDMI output the audio output won't come back to the built in
Speakers as it was previously before connecting the HDMI output.
I understand that may be intentional, however I do believe the audio
auto switch output to HDMI when a cable is connected and then back to
previously default output when HDMI is disconnected should be the
default, if a different audio output would be required than a manually
setting may be ok.
Thanks,
