Samsung Frame TV to AMP? (I don't want to use a soundbar, AMP only)

Hello @triplem, welcome to Sonos Community!

I’m assuming HDMI-ARC from the Frame TV box to the AMP via HDMI cable? 

You are correct, connecting the Sonos Amp with your Frame TV via and HDMI cable would work.

I should mention though that you won’t get Surround Audio that way. You would need a second Sonos Amp which would connect wireless to the first Sonos Amp for the two back in-ceiling speakers to play Surround Audio.

To explain it better:

• Your current scenario:
  • 1 Sonos Amp → 4 in-ceiling speakers → HDMI to Frame TV. Two speakers would play the Front Left while the other two would play the Front Right on a Stereo setup.
• Scenario for Home Theater Surround setup:
  • 1 Sonos Amp → 2 front L/R in-ceiling speakers → HDMI to Frame TV
  • 1 Sonos Amp → 2 back L/R in-ceiling speakers → wireless connection accomplished via the Sonos App for Surround Audio.

I hope this helps.
