sonos playbase to TV via extractor - no audio

Hi! My parents have given me their old Sonos playbase. I have the new Philips ambilight 4K TV which does not have the optical input. We bought an optical to HDMI adaptor and I have set up the playbase on the app, connected to the TV, changed settings on the TV so the audio should be coming out via HDMI but it is still coming out of the TV. When I press the volume the light flashes on the Sonos so it is all connected but just won’t play out of there. 
any advice? Thanks all!

​@Emackenzie10 There is a similar discussion here but for a Play Bar rather than a Play Base. Both require TosLink optical input though:

An important point to note: the conversion is from the TV HDMI output (Arc/eArc) to the PlayBase TOSLINK OPTICAL input not the other way round, as suggested in the title and opening post.

Also TV will need to be configured to use a soundbar connected to an appropriate HDMI Arc/eArc output. There is no control layer with a converted optical connection.

Not sure about your TV but mine needed configuring to 'Use Wired Speaker -> HDMI(ARC) Device' (I paraphrase) rather than 'External Speakers'. There was a difference in my case (an older Panasonic Viera).
