I moved a family room system roughly 3 miles, and every component and every cable was identical all except for a new Comcast box. Integra AVR, Sharp Elite, Oppo, Comcast X1.

I had the system running for quite a while while I was working elsewhere in the house, and all seemed well. Client reports a few seconds of sound drop out periodically. The picture is unaffected. He has a set of Sennheiser wireless headphones that continue to play normally, even when the sound through the AVR cuts out. They get analog audio, of course.

He hasn't tried his Blu-ray yet.

Comcast has come by and given him a different DVR, no change. The original HDMI from the Integra to the TV has been replaced with an Ethereal passive 5 meter, no change.

It is unusual, because the entire system was basically plucked up with a set of tongs and dropped down in a different house.

Is it possible that a clock stretching HDMI splitter may fix this?

Any other clues?
