Hello, from time to time I have problems playing audio from .mkv files. Playback starts, picture can be seen, but no sound can be heard. When I play the file on the PC, the sound works. VLC outputs MPEC AAC audio (mp4a) for the codec information and handbracke shows AAC (avccodec). The playback functions perfectly with my UHD player. My X9S is connected to a Denon AV receiver via HDMI, the installed version is 2.1.30. Is there any setting I can change to make audio work?
