Can confirm this as well.

I solved this by running yay -S pulseaudio-dlna and selecting the third option "pulseaudio-dlna-python3-git".

Then it'd run but I'd get a blackscreen on the chromecast..

I uninstalled it all and reinstalled the 'git' version of the package and it worked perfectly.

Same exact error here.
When I tried to install pulseaudio-dlna it showed only two options and no -python3-git option, I tried to install one of the other versions anyway but unfortunately it didn't fix the problem.

Hi, guys.

Had the exact same problem on Archlinux.
As @BerenLuth said, when looking for pulseaudio-dlna (also using yay), only two options appear and none of them had -python3-git.
But for me it fixed installing the first option which is just pulseaudio-dlna.

Hope it helps!

This is a duplicate of issue: #29. See that issue for another fix, the one here didn't work for me.

Installing pulseaudio-dlna via AUR also resolved the issue for me on Manjaro.
