First off, it's hard to get an answer in the W4100 boards when there are 3 or 4 conversations going on at the same time. I hope to receive a direct answer on this topic
I have had this TV for about a week, and since Day 1 have had "audio problems" with my xbox 360 and ps3 I applied 202r, but no luck.
Heres a description of my "audio problems":
Gears of War 2: In game voice comm is low
Rock Band: Song previews are low
Little Big Planet: When I am in my POD, background music is low.
Metal Gear Solid 4: Codec communication is low
On a possibly related issue, when switching from Cable Box to ps3 or 360, the volume always has to be lowered because for some reason, the Cable Box is very low. There are time when the volume is increased to 40+ when watching cable.
