Neither AAC or MP3 audio files are working for me. The player plays, but I don’t hear anything. I tried changing the passthrough settings and speaker config (although the config worked fine on the older kernel). Nothing helped.
Additional info (but no new logs). I also can’t hear the Kodi GUI sounds even if enabled, nor do I get any sound if playing something from a music addon like Radio. The only sound I can get is on video files. All those are AC3 encoded audio (or something like TruHD for my 4K bluray stuff). And if I turn off passthrough, then I get nothing on the video files either.
Second update: I changed the Output Configuration in the Audio system settings from Best Match to Fixed and that solved the problem. If it’s set to either Best Match or Optimal then AAC and MP3 don’t work. That’s fine, but it’s a change from the 3.x kernel.
