How do I enable audio access for Flatpak applications?

I'm trying to make OpenRGB display a light show based on the music playing, however, audio device selection is unavailable in the application, and upon checking its permissions with flatpak permission-show org.openrgb.OpenRGB, there's no entry for audio access. Maybe I've glossed over some details, but upon a look at the Flatpak docs, I've tried these commands:

flatpak permission-set socket org.openrgb.OpenRGB pulseaudio
flatpak permission-set background org.openrgb.OpenRGB pulseaudio
flatpak permission-set input org.openrgb.OpenRGB pulseaudio

They all complete without errors, although they don't add any new entries to the permissions list. If prefixed with sudo, they all fail with: error: Failed to execute child process “dbus-launch” (No such file or directory).

I've also tried sudo flatpak override org.openrgb.OpenRGB --socket=pulseaudio, though that seems not to have any effect either.

I believe OpenRGB uses OpenAL to read the audio; not sure if that's relevant for the specific case.
