SDMG
Sonic Data Mixer Gate
Class
Parameters (Audio Signal and Timing)
Description
Configures the generator to use either an internal or external audio source for its HDMI
audio output.
Note: Setting the mask “external” bit to 1 causes the SPDIF audio signal to be passed
through the generator. In this case, the Audio InfoFrame CT, CC, SF, and SS parameters
are set to 0, indicating that the stream header should be used to determine audio coding
type, channel type, sampling frequency, and sample size, respectively. If both “external”
and “sdg” bits are set to 1 simultaneously, then an error is generated as the generator’s
sonic data mixer does not currently support proportional mixing of internal and external
sources.
