Comcast Ground loop

I just switched from Directv to Comcast and now I have a nasty group loop. If I disconnect the coaxial cable from the Comcast cable box the nasty noise playing out of all my speakers disappear. Any recommendations? Maybe a Jenson VRD-1FF?

Equipment List: Benq W6000, Darbee DVP-5000S Video Processor, JKP Affinity 100 inch 16x9 .9 gain reference screen, Marantz SR7013 Receiver, 3-Marantz Ma700 and 2-Ma6100 monoblocks, 7.4.2 Atmos, B&W Nautilus 805 front speakers, B&W Nautilus HTM2 center speaker, 2 Volt 6 Atmos Speakers, Mirage HDT-R side speakers, Jamo THX surround one rear speakers, 2 LaVoce 21inch Neo DIY subs and 2 PSA S3600I'S.

I'd start with Comcast to inspect and correct the ground properly and/or resolve the noise issue at their expense.
If that doesn't work, the ground isolator may be the solution.
