Sonos speakers aren’t designed to connect to a TV set, a Ray or Beam are fairly low cost Sonos that are designed to do the TV connection and will share that with your other speakers and Sub.

Arc soundbars are a bit more expensive but do an excellent job.

​@Kailumf,
No, not without perhaps adding more Sonos hardware - ideally (depending on your TV) you need a Sonos Soundbar, or Amp - ‘primary device’ to then bond the Sonos Ones and Sub Mini to it, to give you a TV Home Theatre setup. The current choices are…

• Sonos Ray
• Sonos Beam (gen 1 or 2)
• Sonos Amp
• Sonos Arc
• Sonos Arc Ultra

The only products that where release that could connect to a tv and send the audio to the speakers was the sonos connect gen 1 and 2 and the sonos port but none of these are compatible with the sonos sub mini which is a bit of a let down but I was on a sonos live support chat earlier and they have reported it to their main management about the lack of functionality in the sub mini so they will hopefully soon be releasing a product or update that will let us be able to connect to anything with a aux

That is the only think i can think of is getting their small soundbar and using that or getting the amp and setting it up but to do nothing as don't have any speakers to work with it

Using a Connect or Port for TV sound results in 75ms delay in sound, so no lip sync.

True but isn't really that big of a problem as it will only be watching YouTube videos casionaly I will watch a film but it will be mainly for music just wanted it to be able to connect to a tv but looks like I will have to get a amp or soundbar to get it to work together
