I can't produce your bug I changed to mp4 and two audio and it works, can you try to use cookies, and try to download this video as a test (https://youtu.be/y73SPpeDz2E?si=IH5AmJnAPACPDRgA), and provide your logs, you can find it in the about dialog

I used cookies with a file; in fact, I already had it configured that way, but I updated it. I downloaded the example video you provided, and I discovered that the sound only plays in the MPC player, but the default Windows player doesn't play the audio.

Yeah, it doesn't support it, I guess. Use VLC it's better

I saw that it downloads in Opus format, but I didn't change anything; I just updated to the latest version and that changed. Before, they played without problems in Windows Movies & TV Player, which is what I use.

Okay, I solved it in the same way as the solution you gave me to solve the problem when the video has different audio languages. selecting the audio format

It seems that this lowers the sound in the codec that the player doesn't support.

Gracias por su ayuda
