So I got my cable tv installed.
Sound bar is working just fine when I hook it up to the audio outputs from the PVR box.
Now my only issue is that I have a Samsung TV, where I can put in a USB stick into the TV and play mp4 video files.
It seems whenever I play videos off the USB stick, the sound bar doesn't work.
I'm wondering is it because I have my sound bar connected via the PVR box output,
and the USB stick is being played directly from the TV...
bypassing my audio connection with the PVR box?
The PVR Box has a USB port as well, but no idea what's that for.
