There is no audio for AC-3 and DTS

[arch3rtemp]

What Happened?

I run the preinstalled Videos app to play mkv video files. It plays the video but not the audio. There is no audio. I have installed ubuntu-restricted-extras but to no avail. If I install another video player, like SMPlayer or Celluloid via Flathub, there are no audio issues. I suppose they come with their audio/video codecs bundled.

Steps to Reproduce

Open preinstalled Videos Play some mkv file with AC-3 or DTS audio codec

Expected Behavior

It should play the audio as intended

OS Version

7.x (Horus)

Software Version

Latest release (I have run all updates)

I'm having the same issue. It plays audio nicely when you run non-flatpak version of Videos app.

I have turned on some more logging in app runtime and this is what is printed out:

Warning received: No decoder available for type 'audio/x-dts, framed=(boolean)true, rate=(int)48000, channels=(int)6, endianness=(int)4321, depth=(int)16, block-size=(int)512, frame-size=(int)1006'.

After some random updates this issue resolved by itself
