Some times I do the following: I connect my laptop to a screen with HDMI cable and in the settings set audio output to the HDMI. Later I disconnect the HDMI cable without doing anything to the sound settings and turn off the PC. When I turn on the PC again it thinks that the sound should still go to the HDMI, even though it's no longer connected. Going in to the sound settings the Output Device drop-down is blank, so it obviously knows that the HDMI is disconnected, but it just doesn't make any sound.
That's the main issue I have. Not switching to HDMI sound on connecting the HDMI might be the best default, I'm not sure, but at least you might have some other preference for where you want your sound to come from when you connect it. But when you disconnect, the sound can no longer come from the HDMI, so you never want it to keep to the HDMI output, you always want it to switch to something else. ---- My intuition about what should happen when you connect HDMI: If the current output is trough built in speakers it should automatically switch to HDMI. If the current output is trough mini-jack or other output (meaning the person is using a headset or external speakers), it should keep the current setting and not switch to HDMI. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/1935770 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.
