What Toshiba TV model is it?

Hi Ken, it’s a 32W1333DB/ 32W1334DB LED Backlight LCD tv

That TV has a digital coax audio output (orange RCA).  Get a coax to optical converter, it will be far cheaper than an HDMI-ARC extractor. 

Hi Ken, just checked and it’s the 32W1333DB model

The two HDMI ports on that TV are input only - in other words, they do not have an ARC (audio return channel) so you can’t use those to connect the TV to the Playbar optical port. The TV though does have a Coax S/PDIF out (I believe) - so you need to use that instead.

I just looked on Amazon and found this converter, but can’t vouch for it as I’ve not used one, personally speaking. So please treat the link below as an ‘example’ and perhaps shop around online to see if there is anything better/cheaper, prior to purchase.

edit: jgatie beat me to it.

Thanks Ken!

and thanks jgatie!

Hi Ken and jgatie - my apologies, I meant to get back to you before - to say that you were both right, the coax to optical converter works!

Many thanks for your help.
