If possible, check the earth and whether the digital out you are using is somehow switched to earth or not with the action of the mute.

Reason I suggest checking this is the cracking can be induced with a floating signal and difficulty in syncing. Also check that the digital cable you are using is fully connected at both ends making sure the earth is continuous throughout - some cables do have one end floating.
