Description
Downmix not applied
Force downmix 2/0
Downmix 2/0 is applied if the flags
down_mix_code_validity AND
stereo_playback_mode are both ’0’ in the
bitstream
The notation, 2/0 represents 2 front speakers and no
surround speakers.

Description:
This register selects whether downsampling is used
for input streams requiring sampling frequencies of
192KHz or 176.4KHz. When ’automatic’ is selected,
register is automatically updated to correspond to the
new output frequency.
