The codec is being used, can't reconfigure

[skindstrom]

Love the script, this hissing has been haunting me for a year until I found your solution.

It worked great when I was using arch linux, but I recently switched to Fedora. In Fedora, after running the script the hissing continues. The following error messages are posted in dmesg and journalctl.

snd_hda_codec_realtek hdaudioC0D0: hda-codec: reconfiguring
snd_hda_codec_realtek hdaudioC0D0: The codec is being used, can't reconfigure.

Some googling showed no results. Did anyone else encounter this issue?

Hi @SimonKinds

Maybe pulseaudio doesn't turn off for some reason. Can you verify that systemctl --user stop pulseaudio.s* stops pulseaudio?

I'll try to investigate it this weekend.

P.S. You can start pulseaudio again with systemctl --user start pulseaudio.service

The same issue occurs, even after making sure that no instance of pulseaudio is running.

It's not a very high priority, as I might not continue using Fedora. I was mostly interested if someone else had seen this issue.

Seems like your hunch was correct, pulseaudio was not properly stopped.
The issue was that I was using Gnome, which also starts a pulseaudio service for the user gdm (Debian_gdm on Debian), resulting in one service for the user and one for Gnome.

Only after running

sudo -u gdm XDG_RUNTIME_DIR=/run/user/120 systemctl --user stop pulseaudio.s*
systemctl --user stop pulseaudio.s*

would pulse be fully stopped and could be reconfigured.
Where 120 is the uid of the user gdm.

Not yet sure how to solve it in a good way, but it works in the meantime.
