Fedora Linux 41 HDMI Sound not Working
From https://discussion.fedoraproject.org/t/how-to-enable-hdmi-audio-output-in-wireplumber-on-fedora-41/137313
Here’s what I did:
1. Copy WirePlumber configuration to your user directory
First, I copied the system-wide WirePlumber configuration to my user directory. This allows me to customize the configuration:cp -r /usr/share/wireplumber ~/.config/
2. Edit the alsa-vm.conf file
I then edited the alsa-vm.conf file to configure the HDMI output. This file is located in ~/.config/wireplumber/wireplumber.conf.d/.
I opened the file and modified it to look like this:# ALSA node property overrides for HDMI output monitor.alsa.rules = [ { matches = [ { node.name = "~alsa_output.*" } ] actions = { update-props = { audio.format = "S16LE" audio.channels = 2 audio.position = "FR,FL" } } } ]
I found this solution in this Arch Linux forum thread, which was very helpful.
3. Restart WirePlumber and PipeWire
After editing the configuration, I restarted both WirePlumber and PipeWire to apply the changes:systemctl --user restart wireplumber systemctl --user restart pipewire
4. Switch output to HDMI in GNOME sound settings
Finally, I went to the GNOME sound settings and switched the audio output to HDMI. After that, the audio was routed to my TV correctly.
Important Notes:
You may need to restart PipeWire every time you plug in the TV to ensure it picks up the HDMI output correctly.You can do this by running:systemctl --user restart pipewire
