Problems with Dolby Atmos on PC

anyone else having problems with Dolby Atmos on PC? Only noticed this week (I haven’t played in a month or two).

if i have Dolby Atmos for Headphones enabled in Windows Spatial Sound settings, the sound cuts out when entering a match (or practice range, any game type really). i have to switch to another Spatial Sound setting (or off) and then the sound works again. I can also switch back to Atmos for Headphones and it will continue to work. Makes no difference if Dolby Atmos is enabled in the game settings or not. Other Spatial Sound options (eg Windows Sonic or DTS:X) don’t have this problem.
