M Audio fast track pro problem

[Kurout]

Hey y'all,

So I have some issues working with my friend's old M Audio fast track pro sound card. I was able to connect it to my Pro Tools 12.5 but while I record, the gain is really low and there is so much humming noise that I think I can barely record using it. Now I called up the Service Centre and they say they no longer provide service to the M Audio fast track pro as it's spare parts are unavailable. Why is there a continuous humming I hear?? How can it be fixed??

Another issue is that I have creative speakers (not monitors, the one with the sub, left and right). I tried to connect the left and right speakers to the 1-2 output of M Audio but I get a real real low output. Is it because they need some supply?? Because they work fine as ASIO but then they're connected to the sub.
