Hi Guys
I'm getting a strange fuzz/fizz on top of the guitar sound when using the SPDIF out. Analog out is fine. Its there all the time and more noticeable when using distorted sounds. Although it is there with clean sounds too.
All levels are good no clipping at all. I'm using an Apollo Twin so have to use a SPDIF to Optical convertor. I have tried two different optical leads but still no luck.
any help would be great
John
