Can't set 5.1 uncompressed audio on Xbox One S with my VIZIO 4k UHDTV (m65-d0); 0x80bd0009 ...

On my TV (Vizio m65-d0) I had to turn on hdmi subsampling for the hdmi port the one S is connected to

I'm having the exact issue with my Vizio M65-D0. All settings are correct. But picture keeps getting changed by Netflix.

I'm having the exact same problem, I have a "2016 Vizio P Series" television and my sound system is VIZIO SB3851-D0 SmartCast38" 5.1 Sound Bar System (2016 Model) I have tried every conceivable connection combination from connection the Xbox one S to the
sound bar directly via optical cable, to connection the Xbox to the display with the HDMI and then connecting the display to the sound bay with the optical cable, to connecting the Xbox to the sound bar directly with the HDMI and using ARC. And every-time
I receive the "0x80bd0009" error when selecting selecting 5.1, 7.1 or Bitstream audio output. As well if I set the output from AUTO to HDMI, I do gain the desired sound output (which is drastically improved) but my ONE-S is no longer able to recognize the
4k or HDR abilities for my display. Any help would be greatly appreciated, I'm at a complete loss as far as what to try next.

Same here, brand new M65-d0. With Xbox One S set to 4K display, with 4K and HDR enabled the screen with either go to 'silent static' or freeze image (while I can hear the game continue in background).

HDR is working, but it appears to cause the M65 to crash when in-game. I do not see this behavior in the Xbox dashboard nor game menus.

According to this post from Vizio CTO on AVSForums, it is known issue?

I am having this problem with a Vizio M65-D0 on the HDMI 1 port which is the ARC port supporting 4K@60 with 4:4:4 on 8 bit. I have an xbox one s connected using the xbox one s supplied cable and have tried a different high speed HDMI cable supporting 4K@60,
etc. I have the xbox one s set to 4K HDR enabled and suppport 4K and the vizio tv has the port set to HDMI color subsampling (which is supposed to be for HDR). I get blanking out of the screen both for games and watching netflix. I also occasionally get the
static screen but not as common. I also seem to lose sound, so not getting the game sounds.

I have tried setting the xbox one s to 1080p but with 4k enabled and HDR enabled and still having this problem. I don;t recall having this problem with the xbox one (non s) on this TV but I didn't game as much on that console.
