Hi!
We have a UM7300PUA we bought a few months ago. we have started having a problem while listening though our Onkyo TX-NR656 receiver, where the audio (from any source, I beleive) drops out for 1-2 seconds. it just "mutes" and self-recovers. If we turn off the receiver the internal speakers don't do this. I really don't know if it is the receiver or the TV. I initally thought it was the prime video app on the TV, but we also have a Roku hooked to the TV's HDMI input, and it does the same thing.

Both the receiver and the TV have the latest firmware.

The dropouts occur approx every 1-5 minutes, but are very annoying.

I have not tried new cables, but I will. I'm very skeptical of all the cable voodoo. I have NEVER had an HDMI cable "partially" work.

    It noticed it does not happen with my old TiVo premier connected the same way. Could it be only 4K sources?

    DaveTwoWheels, If the cables are not 4K, I would recommend having them replaced. Normally intermittent video or sound issues can be related to a handshake problem. They can be corrected by using a 4k HDMI cables.
