Ligawo PRO HDMI Matrix 6x2 4K*2K UHD Ultra HD + ARC + PIP + Audio EDID control

£170 for the 6x2 4K*2K and it doesn't even come with a UK plug, which is of course illegal. EDIT: Having contacted Amazon.uk and bought a new adaptor with the discount they eagerly proffered (thanks and all, but chaps, it's still illegal it was shipped without it), this device really doesn't entirely work as advertised - the optical output won't respond to 5.1 or 7.1, downgrading it to 2.0: just left and right front.. The video in/out matrix seems to work fine, though maybe a tad slow to respond (I've nothing to compare it against, so this might be standard - or it might be a lot). But the audio - it says it supports 5.1 and 7.1 via the optical, and from what I can see it doesn't, regardless of its EDID setting. I know direct HDMI from source (PC) to HDMI In to the 7.1 system of my Samsung blu-ray works. I now have to wonder whether HDMI out to the amp in stead of the TV instead will work, although then I'd need a splitter on that channel to send it to the TV. It seems to me options for 4k @ 60 (i.e. HDMI 2.0+) with 7.1.are way too limited.

Hangs after a period of inactivity and doesn't 'wake up'. Works after switching ON/OFF but that's not the intended way of using this product.
