Anyone happy with the SB 36512-F6 soundbar?

Just fine, sure. I’ve had trouble since after its first firmware update late ‘18/early ‘19. Only until very recently, after it received, and my p55-f1 received the most up-to-date firmware versions has it worked okay passing through my Xbox One X.

I’ve mostly had to unplug/replug, soft reset, hard reset, fresh firmware force installs, deleting and reinstalling the Dolby Access app on the XB1X every single day just to get 4K, Atmos, and/or Dolby Vision yo properly work/pass through, and to properly transmit HDCP 2.2 data; think BluRay discs. I do not hyperbolize, it’s been every single day for the pass year, until about ~late March / early April this year that I finally noticed that the tv was properly changing its resolution to 2160p & color to Dolby Vision/HDR10 when playing UHD streaming titles, playing video games, or launching BluRay titles. Without HDCP 2.2 properly transmitting, I wasn’t able to enjoy my movies on disc for over a year.

In addition, if you want it for music, look elsewhere, I must’ve tried hundreds of different settings over the past 1 1/2 years trying to find the sweet spot for music, there is either always too much bass, or lyrics are muffled.

If I were you I’d wait for the 2021 M series 5.1.4, or Elevate soundbar / subwoofer / satellite speaker combos to release. HDMI 2.1 is truly a game changer no matter what your hardware setup will be. Lossless video & audio will mean increased quality, and in theory make bugs virtually negligible/insubstantial.
