Flatpak version does not play audio.

[gegoxaren]

The flatpak version of Celluloid does not play any audio when playing to a jack sink.

This seems to have happened since the latest flatpak version, as I remember it working a week or two ago.

I would suspect it has something to do with this bug: https://github.com/celluloid-player/celluloid/issues/506

I have tried version from the repository and it works there.

$ celluloid --version
Celluloid 0.20

$ mpv --version
mpv 0.34.1 Copyright © 2000-2021 mpv/MPlayer/mplayer2 projects

FFmpeg library versions:
   libavutil       56.70.100

   libavfilter     7.110.100

Here is the version strings from inside the flatpak:

[📦 io.github.celluloid_player.Celluloid config]$ mpv --version

[📦 io.github.celluloid_player.Celluloid config]$ celluloid --version
Celluloid 0.24

I am unable to use mpv form within the flatpak environment, so I can't test it (I get an error that I need to select a video out device).

Thank you for your time!

I figured it out: By adding "--ao=pulse" to my MPV options in Celluloid it started working again.

But it is a strange thing.

Can confirm it solves the issue for me too.

Yep this fixed my issue too. Thanks.

The MPV options are located here:

Edit -> Preferences -> Miscellaneous Tab Extra mpv options: --ao=pulse
