Linux

Since a recent update I have trouble with my audio devices.

Arch, KDE Plasma 6, X11 I mainly use a USB DAC, but sometimes switch to my TVs speakers (connected via HDMI) and that's where I have trouble with.

The problem is the output profile for my TV is not consistent between reboots of my system and/or TV and has to be manually set. The profile is shown in the Plasma sound settings as inactive.

In this instance the pactl list cards shows the first profile hdmi-stereo as active (available: yes). However I can't switch to it in the Plasma sound settings.

off: Off (sinks: 0, sources: 0, priority: 0, available: yes)
output:hdmi-stereo: Digital Stereo (HDMI) Output (sinks: 1, sources: 0, priority: 5900, available: yes)
output:hdmi-stereo-extra1: Digital Stereo (HDMI 2) Output (sinks: 1, sources: 0, priority: 5700, available: no)
output:hdmi-stereo-extra2: Digital Stereo (HDMI 3) Output (sinks: 1, sources: 0, priority: 5700, available: no)
output:hdmi-stereo-extra3: Digital Stereo (HDMI 4) Output (sinks: 1, sources: 0, priority: 5700, available: no)

So far the active profiles were hdmi-stereo and hdmi-stereo-extra2.

I have to manually activate the profile with pactl set-card-profile alsa_card.pci-0000_26_00.1 output:hdmi-stereo, if the profile has switched. If I try to switch to any of the other stereo profiles, nothing happens, I have to chose the available one.

I didn't have any luck figuring out why the profile can change when I reboot and how I can activate one profile automatically without manual input.

Any help or advice would be appreciated. Thanks for reading.
