Hello! I've just updated to the latest driver which are 24.6.1 which also updates the amd hdmi audio driver ("amd high definition audio device"). Now the maximum bit depth for audio is limited to 16 bit and 48 kHz. With the previous driver (24.3.1) it was 24 bit / 192 kHz. Does anybody have the same problem?
UPDATE: looks like it is the limitation of the eARC tv option, so drivers are ok. Sorry!
