So the game works fine, with the exception of the audio. Does anyone had the same problem and were able to solve it?

You should say which game of the series you are talking about.
You should also give more information about your system (OS, hardware, etc.).

Ops, I forgot!

The game is Carmageddon Max Pack.
I use Windows10
Intel core5 6200U
Cores 2
12GB of Ram
Imtel HD Graphics 520

Thanks for the attention!

This is strange.
If I'm not mistaken the game uses DOSBox to run, so I'd check if other DOSBox games have the same problem. You could install a free DOSBox game such as Tyrian 2000 just to make a quick sound test.
