Those speakers are not meant to be used with TV, unless you use them as surrounds with a Beam, Playbar, Playbase, or Amp as the fronts.

Hi, Kimono. Welcome to the community. This configuration is not going to work well, I’m afraid. In theory, you could use Line-in to one of the PLAY:5’s whilst it is stereo-paired to the other, then group in the Sonos ONE’s, which I suppose could also be stereo-paired. At best, this will be an odd-sounding configuration with some level of delay in the One’s, and at worst, it will be rather susceptible to audio interruptions. As such, I can’t in good conscience recommend going about it this way. 

Further to my point above, jgatie is entirely correct. To use these as true surround speakers, a PLAYBASE, PLAYBAR or BEAM would be required.
