Dolby 5.1 help

Hi Folks,

 

I have a Motorola 6416 PVR connected via HDMI to a  Sony STR-K900 amp with Dolby 5.1 via the red and white RCA jacks.  I think I was always getting Dolby 5.1 sound.  This weekend I upgraded my TV to an  LG 65LM6200 connected via HDMI to the TV.  I've turned off the sound on the TV and run the sound through the 5.1 like I did before, but the sound seems to have changed and become very hollow.   When I go into my PVR audio settings the only options now are "speakers" "stereo" and "advanced".  I always thought Dolby 5.1 was an option?

The sound on the system has become really hollow and really mono...

 

All speakers are functioning and connected correctly.

 

TV speakers are off...

 

Any thoughts on how I can get Dolby 5.1 back?  (i was thinking I could maybe run an optical audio off the TV into the optical audio input in the Sony amp... ) but am I missing something obvious here?
