Last week: purchased from Costco: Samsung new Soundbar Q7CB 3,2,1ch. Supposed to be excellent, but after talking to the Samsung tech. support, you can't have more than ONE HDMI plugged-in on the back of your Samsung-4K QLED TV.
Only ONE for Soundbar must be plugged in, otherwise TV - SPEAKERS will be your Default. You need to keep changing to correct speaker "eARC sound output" options. This is terrible, on the back of TV, there are 4 HDMI connections I have, and Soundbar HDMI Must go to eARC area, than why does it matter? No matter what, IF U plug like AppleTV, GAME HDMI back of your tv, than you are **bleep**. Its headeach... trust me. I would NEVER Buy such a soundbar, is not compatable with their own new 4K tv's. I think, Samsung knows, but don't wanna say anything. I am so tired of this, ON/OFF and keep changing ALL SETTINGS, HDMI, Plug/Unpluging and spent 20min. with tech. from Samsung. NO WAY OUT. Please Don't buy it unless U know something I don't. Pl. email me SPRING518519@GMAIL.COM - IF U have any solutions. Thank you. - Roger.
