Widget type = Pin Complex
Number of sample delays through widget
Reserved
No left/right channel swap capability
No support for Power State control
Widget supports an Analog stream (since
the digital microphone input is a SDM signal
that needs to be processed by the digital
filters, it is not a true bit for bit digital stream
like I2S or SPDIF where samples are
passed through unchanged)
No connection list is present
No support for Unsolicited Response
No Processing Controls parameter
No support for striping
N/A for pin complex
No amplifier info; use default amplifier
parameters from Audio Function node
instead.
No output amp
