Help old guy w receiver audio setup...

Have a Sony STR-DG810 that I run everything through to the TV.
- HDMI in from DTV box
- HDMI out to TV for video
- Stereo receiver for audio.

Pretty sure I setup the receiver to not output any audio thru the HDMI cable so I didn't have to mess with keeping the TV volume at zero.
I cannot get any sound from the TV speakers at all on either the original TV and second / new

Still using the stereo for sound for the original setup.
Problem is that I just piggy-backed another TV in the kitchen off this DTV box by using a powered HDMI splitter and long cable.
Now because of this setting I am not getting sound thru the HDMI.

Can someone help the 'technically inept' old guy figure out what to change back?
I want to keep using the stereo in the den for audio (I'll turn TV volume to zero) and then use the HDMI for audio to the TV in the kitchen.

I'll try a link for the manual but think I remember this site does not allow links. If so; please google "Sony STR-DG810 manual" for reference.

BTW - bought a 75' HDMI cable & powered splitter from MonoPrice and it works great. Just want to turn on the audio thru the HDMI so I don't have to crank up the stereo in the den in order to hear in the kitchen :helpme

Thanks for the help.

Never Mind...
Just discovered the HDMI control instructions were in a separate manual :banghead:

All good now :D
