After starting my PC sound ouput "HDMI/Display Port - Eingebautes Tongerät" is selected in the options GUI, which doesn't work so I have to switch to "HDMI/Display Port 3 GP 106 High Defintion Audio Controller".
I tried some solutions from this post How do you set a default audio output device in Ubuntu? but they don't work for me.
What I realized was that as long as I don't change my sound output pactl list short sinks lists
2 alsa_output.pci-0000_00_1b.0.hdmi-stereo module-alsa-card.c s16le 2ch 44100Hz SUSPENDED
7 alsa_output.pci-0000_01_00.1.hdmi-stereo module-alsa-card.c s16le 2ch 44100Hz SUSPENDED
But as soon as I change my output also the result of pactl list short sinks changes to
2 alsa_output.pci-0000_00_1b.0.hdmi-stereo module-alsa-card.c s16le 2ch 44100Hz SUSPENDED
8 alsa_output.pci-0000_01_00.1.hdmi-stereo-extra2 module-alsa-card.c s16le 2ch 44100Hz IDLE
I think, that alsa_output.pci-0000_01_00.1.hdmi-stereo-extra2 is actually the sink I'm looking for but I cannot set it as default since it's only available after changing outputs manually.
Is there any solution for my problem or is possible to have a script that selects the correct output at OS start?
OS Version is Ubuntu 22.04.1 LTS.
