In MuseScore 4, there's no sound output when inputting notes, and playback hangs at the position it's started. This is fixed when pipewire-alsa is added to media-video/pipewire use flags. Reproducible: Always Steps to Reproduce: 1. Use an openrc pipewire-based system with the following USE flags: media-video/pipewire sound-server bluetooth media-video/pulseaudio -daemon 2. Ensure gentoo-pipewire-launcher has ran. 3. Open a score. Inputting music will cause no noise, and playback will hang. 4. Now, add pipewire-alsa to the USE flags of pipewire. Rebuild pipewire. 4. It should work now. Actual Results: On running mscore, `ALSA lib /var/tmp/portage/media-libs/alsa-lib-1.2.9/work/alsa-lib-1.2.9/src/pcm/pcm_dmix.c:999:(snd_pcm_dmix_open) unable to open slave` is printed to stderr. However, following my steps fixes it. Expected Results: MuseScore 4 sound should work with less manual intervention. openrc amd64/23.0/hardened with Wayland WM and gentoo-kernel-bin, sof-firmware. Machine is younger than 5 years old. I tested the above on both musescore4 built from source, and an unpackaged MuseScore4 extracted appimage
