Public bug reported: On each boot, an incorrect audio output device is selected, at least when HDMI audio output is in use (still need to test the TV/aux output; will update the bug when done).
Specifically, the settings application lists "Multichannel Output - Built-in Audio" as the selected output device. However, for audio to play through the connected HDMI device, "Analog Output - Built-in Audio" must be selected instead. Unfortunately, this setting will be lost on subsequent boots. A workaround is to remove the following lines from /etc/pulse/default.pa: ### Use hot-plugged devices like Bluetooth or USB automatically (LP: #1702794) .ifexists module-switch-on-connect.so load-module module-switch-on-connect .endif However, removal of these lines will (as the comment suggests) result in hot-plugged USB devices *not* being automatically selected. ** Affects: pulseaudio (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1899962 Title: Wrong audio output device selected on Raspberry Pi Desktop To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/1899962/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
