Win7 Ultimate
Centrafuse 3.6 nav

I've been having a problem for the past couple of months with intermittent glitches in the playback of my HDRadio. Every 5-10 seconds it will do a "the-the" and then continue. This came on recently after running for maybe a year successfully. Tried buffering on and off, tried moving the control box to see if it was interference. Recently rebuilt the OS from ground up (unrelated issue) and the problem persists.

Any suggestions?

Thanks,
Joel
