Sirius distortion using SCC1 / MJS with Centrafuse

Hi everyone. Longtime lurker, first post here. I'm finally putting my system together, bench testing now.

I'm getting some distortion when using Centrafuse with SCC1 and Mitch's USB adapter. It's not a lot, it sounds like listening I'm to an AM station that is not finely tuned.

Oddly, using Roadrunner, Sirius comes in crystal clear - no distortion what so ever.

I've searched the forums here and on Centrafuse and have not found anything that could help me. It sounds like it might just be a minor adjustment in a config file somewhere - if I could only figure out where....

Any ideas?

I would check the levels in the mixer for your mic line level and lower it some. This can cause distortion.

Thanks Raygun. I've been playing with it all evening and what I have found is that when I use Buffer ON in the Cetrafuse settings for Satellite, I get the distortion (and yes the line-in is muted as it should be.)

When I turn off buffering, the sound quality was way improved. So this tells me that it has to do with a quality of the recording done for buffering...so I'm off to figure that one out.

OK - worked it out. I downloaded the Vinyl Deck utility that works with AC97 on board sound that came with my VIA MOBO. I was able to tweak the record level settings for line in and remove the distortion that way. Oddly, the level setting just barely needs to be turned up in order to get good sound. Just a bit too much and the sound distorts again.

Ugh - I monkeyed around with the windows audio controls to no avail for hours before I did this - could have saved lots of time...
