I developed a problem last night I can't fix. My HR22 suddenly has no audio. It started with one channel, then it got to the point where all channels have no audio. At times, I could get audio through one channel. But as soon as I changed it to another one to see if it had audio and then changed it back, the audio went away again. We have some heavy rain last night. So I'm wondering if it's an issue with the dish, my HDMI cable, or the receiver. There was still no audio this morning.
