Audio out from HDMI to TV cuts out

I'm looking for help to troubleshoot the following problem:

I have a brand new iMac, 27", i7 (my first Mac ever). Using the Moshi Mini DisplayPort HDMI adapter, I output video and audio to my LG 55LH90 1080p LED TV. Everything is fine except that approximately every 15 seconds, the audio will cut out for 2 seconds completely.

The problem occurs regardless of whether the audio is from iTunes, YouTube, VLC, Quicktime, etc.

Does anyone have any ideas about what could be causing this problem or how to fix it?

Thanks

iMac i7, Mac OS X (10.6.4)

Cmaster: I am having the exact same issue through my TV and receiver setup w/ moshi MDP - HDMI. Tried a bunch of different configurations, going just through TV, cables, digital, optical, everything, and the sound still cuts out but about every 20 or 30 seconds for 2-4 seconds. I hope someone can figure out a solution to this!!

Any help would be greatly appreciated!! Thanks!

I have solved my problem.

After spending an inordinate amount of time trying to troubleshoot this (trying different cables, adapters, settings on my TV and iMac, different devices, scouring the internet for help, etc.), and with both LG and Apple customer service pointing the fingers at each other, turns out Apple was right (and LG was incompetent).

The fix was simple. When I was about to give up, I played around with my TV settings one more time. I disabled the "Clear Voice II" setting on my LG TV and it made the problem go away. Audio is 100% fine over HDMI now. Hurray!
