The soundbar is as you say, ‘solid‘, as it’s a set of stereo, centre, Dolby height pair and I think bass speakers with all amplification as discreet channel amps in the TV. So you can simply use HDMI as the soundbar needs a powered amp, as in the TV.Thanks for the reply.
Did wonder whether the soundbar could be wired with an HDMI to repurpose it, took out 40+ screws and it was still absolutely solid. Couldn't get into it at all! Might try again at some point or see if existing connector can be changed.
So, to reuse, you’d have to get a Dolby Amp with the 3.1.2, or as many of the drivers you want to use. Then either rewire (or cut off) and connect the the wires at the soundbar connector to the speaker outputs of the amp, probably using longer cables. You’d also need to identify the colour cables Philips used, as looking at the connector they seem to use ‘car audio’ common grounds which can cause some amps issues.
I was thinking of such a project but I didn’t get as far as identifying the mulex-type connector or the speaker lines - would be easy enough with a test line or meter.
