Sound Cutting Out

I know a lot of people have posted about this but I switched the HDMI cord out and the sound is cutting out still and only when I'm watching through the cable box. I see people referring to the STB Verison and what is next to it. This is what mine says: PXD01ANI_4.0p19s_PROD_sdy. Someone please help, I also switched the cable box and still the same thing. Its only happening in my master bedroom.

Thanks
