Hi Bas,
No guarantees but maybe this will fix your problem. I had the same problem a
couple of years ago. The sound was more thmmp thmmp thmmp than cr-cr-cr. It
was driving me crazy. Here's how I solved it:
1. open kmix
2. click on the Input tab
3. Lower the CD slider (it's 2nd from the left on my installation) almost to
minimum.
The cr-cr-cr should go away.
Let us know if that works.
Cheers,
Jonathan
