I didn't know we got C-span in the clear until a couple days ago and dialed it in on C3-7. But I'm not getting any audio on my 922.

What do I need to do?

looks like the audio is 6.80 only. Make sure the audio setting is correct
CSpan radio is at 5.20 audio by the way

I checked both on
mono and stereo
narrow and wide
etc etc (all the options in other words) and it was on 6.8 and still nothing
Do they not always have audio?
Is it just video at times?

I tryed my DSR-920 on C4 - 7 and got video and audio. Also weird thing I also tried other channel on c4 and am getting audio wonder if they made it clear now.

It must be the way I have it wired into and around my HDD201 box.

Yah that must be it

My upstairs TV (which is hooked to the F connector on the back of the 922) gets audio.
