I have an HTPC with an Intel 10700k and AMD 7900XT graphics card. The 7900XT is hooked up to an AVR via HDMI 2.1. When I go to desktop mode I can select either 5.1 or 7.1 in the KDE sound settings, switch back to game mode and the Dolby Surround persists, but once I reboot, it forgets and reverts back to 2.0 stereo until I go back to desktop mode and set it again, anyone have any ideas?
