I have had the YSP-2200 for a few years now & it all worked great with my Panasonic Viera HD plasma TV. I have recently upgraded to a Samsung QLED 4K set, plus a Sky Q UHD box & I can no longer get HD sound via the ARC on my TV. I now have to connect the Sky Q UHD box directly to the TV & the only way I can get sound via the Soundbar, is via an optical cable. Is this the best way for it to work & would I have to upgrade to a better soundbar to get the full potential from this recent upgrade??
