Yes, you can transfer the sound from your Philips TV to the optical connector of your Sonos Ray by using an HDMI Audio Extractor. This device can extract the sound from an HDMI signal and send it to your Sonos Ray via an optical cable. The Delock HDMI Audio 5.1 Extractor offers an optical TOSLINK output that is suitable for this purpose. You need to route the HDMI signal from your TV to the extractor and connect the optical cable from there to your Sonos Ray.
