IO error when playing sound

[Michael Tsang]

When using pipewire, sound doesn't play through HDMI. In KDE Audio settings, choosing the HDMI output and playing test sound fails with IO Error. Playing to the internal speaker works.

If I use Pulseaudio instead, sound plays normally.

The controller is Alder Lake PCH-P High Definition Audio Controller.
