No sound output through HDMI after upgrading to 24.04.01

[jrwatts]

I have discovered that I no longer get any sound output if I select any HDMI option for the output device on my Framework 13 laptop, after upgrading from Kubuntu 22.04 LTS to 24.04.01 LTS (it was working fine before the upgrade). Built-in speaker output is working fine. Not sure where to start troubleshooting, so can someone help? I did notice that all the duplicate HDMI output options vanished (e.g., HDMI 2 Stereo, HDMI 2 5.1, HDMI 3 Stereo, etc.), but I never needed those options before, either, no matter which HDMI port I used.

Did you look at system config>hardware>audio> hdmi card setup? Mine is off by default. I dont use this anyway.

I concur. Also, check system settings regarding audio. I had to do the same after I had updated my wife's machine.

System Settings -> Hardware -> Audio gives me the following options:

1. Off
2. Analog Stereo Duplex
3. Analog Stereo Output
4. Digital Stereo (HDMI) Output + Analog Stereo Input
5. Digital Stereo (HDMI) Output
6. Digital Surround 5.1 (HDMI) Output + Analog Stereo Input
7. Digital Surround 7.1 (HDMI) Output + Analog Stereo Input
8. Digital Surround 5.1 (HDMI) Output
9. Digital Surround 7.1 (HDMI) Output
10. Analog Stereo Input
11. Pro Audio

None of the HDMI options output any sound when I test them. The "Pro Audio" selection lets me choose from:

1. Built-in Audio Pro
2. Built-in Audio Pro 3
3. Built-in Audio Pro 7
4. Built-in Audio Pro 8
5. Built-in Audio Pro 9

If I select the first and test, I get static from the left & right built-in speakers; the other options get me silence.

I'm guessing it's either a problem with PipeWire configuration or a conflict between PipeWire and PulseAudio, but I have no idea how to continue troubleshooting at this point.

Edit: I'm connecting to an Onkyo TX-RZ50 AV receiver, which is connected to a Samsung 4K TV,

Do #2 or #3 work by any chance?

There (probably) is no conflict with Pulse and Pipewire , as the main pulseaaudio service should not be running.

lets check some things:

What audio hardware do you have?

$HOME/.local/state/wireplumber/

use alsamixer to both see which chip is being used, as well as checking that something hasn't been disabled, though this probably won't be obvious at all.


You can also try to reset pipewire/wireplumber by deleting
$HOME/.local/state/wireplumber/ and $HOME/.local/state/pipewire/media-session.d/ (if present) and
$HOME/.config/pulse/ (if present), and reboot.

Yes, #2 & #3 work through the built-in speakers.

Here's my output from those commands:

alsamixer shows "Card: HDA Intel PCM" and "Chip: IDT 92HD95" (This is a 2nd generation Framework 13 laptop, with Intel i7-1260P.)

However, I get this:

$ ls $HOME/.local/state/wireplumber/​
ls: cannot access '/home/jonathan/.local/state/wireplumber/​': No such file or directory​

$HOME/.local/state/pipewire/media-session.d/ also doesn't exist.

I tried deleting $HOME/.config/pulse/ and rebooting, and it was re-created, holding a single "cookie" subdirectory (and still, only the built-in speaker output works),

edit: if I manually type the command instead of copy-pasting, the wireplumber state directory does exist:

$ ls .local/state/wireplumber/
default-nodes  default-profile  default-routes  restore-stream
