Bought a Sonos Arc today and came home to set it up. Went through the setup instructions provided by GuitarSuperstar here:
The setup went smoothly except that the “Select HDMI Input Audio Format” option is greyed out and I can’t change it to ‘Bitstream’ as instructed - it’s still set at ‘PCM’.
Not sure where to go with this. :-/
