No sound on a video with AV1 - Opus

I can play the same file with audio on MPC-HC. It is an Mkv file with AV1 codec and Opus (@256 kbps VBR, 48000Hz , 5.1).
On Vlc, video plays fine but there is no sound. On statistics tab it shows decoded block numbers but played number is 0.
On Windows 11 23H2, latest VLC version.

Same report about OPUS audio in MKV as the one from this thread:
https://forum.videolan.org/viewtopic.php?f=14&t=164761
But your file is playing fine wih other players, including FFplay.
You should create a new report ticket on the VLC issues tracker with your above report, the link to your sample file and the link to this thread:
https://code.videolan.org/videolan/vlc/-/issues
If possible, because of this:
