No audio on the default KDE Plasma installation

There was no audio in the default Plasma desktop installation that I got from running setup-desktop. I used Alpine version 3.18.2 and also tried on edge, where the issue persisted.

When using the audio system settings to test audio, clicking Test Speaker, then Front Right the error: 'Error trying to play a test sound. The system said: "Invalid state"' was given.

After some troubleshooting and reading online, I got audio to work again by installing the pipewire-pulse package and rebooting.

Maybe there was some conflict between audio packages or running audio systems?

Installed Pulseaudio packages after setup-desktop:

~ $ apk info -v | grep pulse
libcanberra-pulse-0.30-r9
libpulse-16.1-r10
libpulse-mainloop-glib-16.1-r10
pulseaudio-16.1-r10
pulseaudio-alsa-16.1-r10
pulseaudio-bluez-16.1-r10
pulseaudio-openrc-16.1-r10

Installed Pipewire packages after setup-desktop:

~ $ apk info -v | grep pipewire
kpipewire-5.27.6-r0
pipewire-0.3.74-r1
pipewire-libs-0.3.74-r1
