when i was encoding a dts 5.1 ch audio that had the layout of C L R Ls Rs LFE , file using ffmpeg via libopus , i found that the resulting file did not play in vlc, due to the channel layout being rewritten to L R C Lb Rb LFE. however if downmixed to stereo, there would be sound. command used:

ffmpeg -i out.dts -c:a libopus -b:a 160k -af "channelmap=channel_layout=5.1" out.opus

I was having a similar issue and it looks like mine was a regression with VLC and a fix has been merged for the next release (3.0.22). The original bug report has a test file that doesn't work for me on VLC 3.0.21.
