508 Audio will not work

[rtt2]

I cant get the audio on my 508 to work. My audio system seems to be working because the DVD player is working fine. I was watching tv and suddenly the audio just stopped working.
Before I start pulling my system apart does anyone have any suggestions?

Problem apparently got fixed. Didn't do anything - I wonder if it was something on Dish's end?
