Ive recently purchased a q800t sound bar. I'll admit im not impressed.
when I have the sound mode set to surround some of the audio sounds what I can only describe as flat and robotic. ie someone got thrown through a wall. and it was lifeless. I thought it was a faulty bar at first, I was on the xbox and the dialogue was just awful, tinny digitised robotic and flat. but the second was the same.
Is there a change in the modes - I had a q70r before and never a problem. surround mode was selected no issues.
Setting to standard seems to help but something seems missing.
I had same problem. I read there was a firmware update. I done this and it fixed the distorted sound. I installed the zip file to my PC, then extracted the file to USB stick. popped the stick into the soundbar and it was installed in about 2 minutes. problem solved. https://www.samsung.com/uk/support/model/HW-Q800T/XU/
