Sound issue on my twitch VODs

Hello,

I have a problem that I can't seem to fix. I'm streaming just fine where you can hear everything (my voice, the game, and the music), but as soon as I check my replays, there's absolutely no sound, not a single noise. I don't understand; I've checked for copyright warnings regarding the music, but nothing at all. I really don't get it, and yet in the 4 previous livestreams, there was sound. :/

Configuration: Windows / Edge 97.0.1072.62
