Play all audio tracks in a file?

[Xenos]

Hi,

As an editor, I usually get xdcam mxf files with 8 audio tracks (before mixing).
For example, channels 1 and 2 have the actors talking, 3 and 4 audio fx, 5 and 6 voice over, 7 and 8 music.

The problem is that all media players I tried, play only the first two audio tracks and ignore all the other. In order to hear all audio tracks, I have to import those files in my editing software, which takes time.

Is there a setting or maybe a command (I couldn't find anything in the mpv manual) that I could use to make SMPlayer play all audio tracks in a file?

Thanks in advance,
Xenos
