Intermittent audio with TX-SR309

Have a brand new TX-SR309. I have an LG 55LW5600 TV, and when I'm using ARC (1.4 HDMI connections for ALL), the audio/video from my STB and BluRay work flawlessly. But when I'm streaming Netflix. Vudu, YouTube, etc., directly from the TV, the video works perfectly but I have an intermittent, 1-3 second audio drop out. I can hear the audio from the TV speakers perfectly when I bypass ARC, but when using the receiver and ARC the audio intermittently drops. I've switched cables, inputs, etc., but it continues to do this and it drives me CRAZY. The streaming video/audio from my wifi enabled bluray works flawlessly with no audio loss. I'm using the TV/CD input on the 309 from the TV, so it's definitely a receiver issue. Any ideas?

Hi Longshanks,

Have you checked with LG's 2nd or 3rd tier support on this as this does not happen on other TV manufactures. Also have you updated to the latest firmware on our unit yet? If not please give that a try.
