E-mu proformance level issue

I bought an e-mu proformance module which is faulty.
The led lights up and responds to midi signals but no sound output…
I maxed out the gain and volume of my amp and i could slightly hear the sound at verry low level behind the amp buzz.
So i guess the internal amplification of the module have an issue, could anyone of you help me to identify the faulty components to be replaced?
Thank you!

I might try to replace this ic (NE5532P)
If someone has another Idea…
