Table 26 S/PDIF Tx 1 Node Summary Information
The S/PDIF Tx 1 node controls the formatting of the IEC-60958-3 compatible S/PDIF output stream.
Under default conditions, the S/PDIF Tx 1 node will process data received from the HDA interface. In
this case, the S/PDIF stream is controlled directly from the Stream Format Verb, as illustrated in
Figure 14.
Figure 14 S/PDIF Transmit Function
It is also possible to select ADC1, MIC1 or MIC2 as the data source, using the vendor-specific
Internal Path Verb.
When ADC1, MIC1 or MIC2 is selected as the input to the S/PDIF Tx 1 node, the Mult / Base / Div
fields in the Stream Format Verb become read-only and are set according to the selected source
node.
