We were moving boxes around, and unplugged only the power cord from the xfinity box, at the box, after turning everything off.  Then, after plugging back in and waiting for xfinity to reboot, we get picture, but no sound.  The hook-up is, cable in to xfinity box, xfinity box to hdmi sat/catv in at receiver, hdmi tv out  from receiver to hdmi-in on tv .  As always, "it was working before."  Any suggestions?

Try hitting the mute or lang button on your remote.

No, not a mute problem.  All sound buttons on.  This happened the other night, without any unplugging,  just after installation, and after some random wire pulling out and re-inserting and rebooting, etc., all of a sudden it came back on.  I'd replicate that if I knew what I had done.
