Bug audio "opus" and AV1 in a "mkv" container

The audio format OPUS and the MKV container were added recently to DVR.
They work great when they are in a MP4 container.

But the OPUS audio tracks doesn't show up when they are in a MKV container, just the video track.

With an AV1 video track, the MKV can't be imported in Resolve.

A file with AV1 (and AVC) + OPUS in a MP4 container can be imported in Resolve

Edit
new samples to test with new link : https://www.swisstransfer.com/d/fb6c9c00-6cdb-4eef-900d-dac411d6daa8

I can confirm this for a Mac.

I tested this. I didn't check for the AV1 in the MKV container

AV1 + OPUS in MKV : Can't import
VP9 + OPUS in MKV : Only video

AV1 + OPUS in MP4 : Can import
VP9 + OPUS in MP4 : Can import

You can test it with these 4 files here : https://www.swisstransfer.com/d/fb6c9c0 ... c411d6daa8

I´m unabble to import OPUS format by itself.
I need to convert it to MP4 and then i can import it, WTF

Well "Opus by itself" is technically Opus in Ogg and Ogg container seems not supported.
