Comcrypt 4000M

[AllBrain]

I am from South Africa and here we have a channel called M-Net, that I am trying to hack. I use a Comcrypt 4000M decoder and applied the 4000M mod on it. The mod works just fine, but the sound is encrypted. How would I proseed to hack the sound?

[I'm sorry, i don't know anything about the sound. I would ask you if you could send me the details about the modify for comcrypt 4000m.
Thank you so much.
