You will need to use a Sonos product that has a line-in or Bluetooth RX as follows…

• Port/Connect (no BT Rx)
• Amp/Connect:Amp (no BT Rx)**
• Five/Play:5 (gen2) (no BT Rx)**
• Era-100 (has BT Rx) (requires additional dongle)**
• Era-300 (has BT Rx) (requires additional dongle)**
• Sonos Move 2 (has BT Rx) (requires additional dongle)
• Sonos Roam/SL - has no line-in, but has BT Rx only

** Note: If any of the above compatible devices are used as a HT Surround, then their line-in port and Bluetooth Rx both become disabled.

Once the TT is connected it can play to any/all Sonos products - a line-in connection is the recommended/preferred option.

Here are links to the two Sonos adapters that are currently available to use (if required):

• https://www.sonos.com/en-us/shop/sonos-combo-adapter

Be advised there’s currently a problem with the bluetooth connection for some users, see 

Most stable would be a cabled connection, either using the dongle for a speaker that needs one, or directly for devices that can do that.

I’d sure go with a wired connection, quite often the Bluetooth link will pass lower quality sound than wired or WiFi.
