no audio at N64 - Recalbox 4.0.2

[peschto]

Hello,

I already wrote this in the german section but I do not received any reply until now, so I want to try it here.

I do not have audio with any N64 game.
PSX, NES, SNES etc. works.

I saw on YouTube that somebody had audio at Mario Kart 64.

My Recalbox is connected via HDMI.
Do I have to open config menu or do I have to enable it at the computer?

Many thanks in advance !

Regards
Tobi
