Sound issues with contour?

hi, just got cox installed about 2 weeks ago, beginning to think I made a mistake, the sound is horrible, 

i can stream Netflix and the sound is fine, so I know it's not the TV. 

i also tried all the troubleshooting online and unfortunately tried the directions on setting volume control to audio device on remote, dint know how to undo that :( 

this us was the second box the installer tried so maybe here is a sound issue,. 

Im beginning to regret switching to Cox
