No sound in 0AD Flatpak (version 26)

[abdilra7eem]

Hi all,

I'm running Fedora 37 Workstation. I installed 0AD from Flathub (Flatpak) version 26. The game runs and I can start a game and change settings, but the sound isn't working.

I looked into the sound settings in Gnome while the game is running, and I see "pyrogenesis" in the list of apps with sound output.

I ran it from the terminal, and I see the following lines in the output:

[ALSOFT] (EE) Failed to set real-time priority for thread: Operation not permitted (1) [ALSOFT] (EE) Failed to set real-time priority for thread: Operation not permitted (1) Sound: AlcInit success, using OpenAL Soft

Fedora uses Pipewire (with PulseAudio support) by default, and OpenAL-soft is installed.

I checked the Flatpak permissions, and they are set properly.

I was told that SuperTux also uses OpenAL-soft, so I installed it from flathub, and the sound is working without issues. I double-checked the permissions and compared the two; all set correctly, so this is definitely not a permissions issue, and ALSoft works normally from Flatpaks.

I installed 0AD rpm package (same version) from the Fedora repo, and it's working without issues. I also noticed that the Fedora build has a much better performance than this build.

This is most likely a bug in the Flatpak build of 0AD. I don't have another system to reproduce on; I hope the community can help in this.

I experienced this exact same issue with WarZone2100 (net.wz2100.wz2100).
