Broken sound playback in AppImages #1033
Our current AppImage releases are unable to play sound, though movie export is unaffected. The root problem is that linuxdeployqt currently lacks proper support for GStreamer and does not include required modules (most likely sinks in our case). Due to the nature of the problem, playback might still work on some distributions, but beyond the tested systems this issue is likely to affect most modern and/or non-Debian-based distributions (as our AppImage build system is Ubuntu Trusty). Fortunately, it seems that the issue can be worked around on our side (see Further Information below).
During playback of an animation with sound clips, the sound clips can be heard through the systems audio hardware.
The sound clips cannot be heard.
--Steps to reproduce--
Open any project containing sound, then attempt to play it back.
The original report on our forum concerned an unknown version of Pencil2D on Fedora 26. I have confirmed the issue with our released AppImage of version 0.6.1.1 on Arch Linux.
