TiVo Roamio Pro - Audio Issue

Hello All:



I have an interesting issue and admittedly I don't know whether it is a TiVo, HDMI cable or A/V Processor issue but here goes:



Often times, when I change a channel on the TiVo, as soon as the screen changes, the audio will become garbled, almost as if you are playing an LP on too slow a speed on a turntable. It solves every time by hitting pause and then play. I'd love to figure out why it does this but has anyone else experienced this?



Thanks,

John
