Good day, I finally got my 486 running and thought I would play me some SC2000, for music I selected the MT-32 as I have the McCake board running, and the audio is nice, but I get the occasional crackling in the left channel, so I swapped from the MK1869 I was using to a trusty SB16 (with a good firmware) and still got the same issues, so I swapped out the old Yamaha speakers with some new Edifiers I had laying around... still have the same issue, My question is the only thing left is the McCake, I'm not sure what to try next. I don't get the crackling in any other game I have played with, though I have not played anything else as long as I have SC2k.

Any suggestions to try next?
