SUMMARY *** As the title states, dragon isn't detecting any audio in certain video files. This is file type independent, and I haven't been able to observe a meaningful pattern w.r.t. which files simply fail to have their audio registered. Command line execution of functioning and dysfunctioning files of the same type reveal no difference and flag no warnings or errors. This portends to be a failure to detect any audio whatsoever, since "Audio Channels" doesn't become accessible, and my plasma sound widget claims no applications are playing any audio. I have observed this with both .mkv and .avi files. I have verified that said files play correctly on a variety of different players, including bare mpv, vlc, and haruna. STEPS TO REPRODUCE 1. Open some particular video with dragon. 2. No sound plays. OBSERVED RESULT No sound plays on some files where sound is expected, and no hints to why are given. EXPECTED RESULT Every file with any sound at all will play said sound or throw an error if it isn't possible to SOFTWARE/OS VERSIONS Linux: Arch 251, zen kernel 5.19.10 KDE Plasma Version: 5.25.5 KDE Frameworks Version: 5.98.0 Qt Version: 5.15.6 ADDITIONAL INFORMATION The smallest file I have which generates this error is still 20 Mb in size, being a 1 minute clip from a movie. How would you like it uploaded?
Are you using Dragon with the GStreamer Phonon backend or the VLC Phonon backend?

(In reply to Nate Graham from comment #1) > Are you using Dragon with the GStreamer Phonon backend or the VLC Phonon > backend? Gstreamer, I think (no VLC installed on system). A little digging suggests that this may be that any file which was ripped from bluray simply cannot be played with GStreamer (on Dragon) regardless of its present file format. Is that the issue?
Yep. and additionally, the GStreamer has been unmaintained for years. The VLC backend is the only supported one. You don't need the VLC app itself to have the VLC backend installed.
