CLARIFICATION OF OUTPUT CONFIGURATIONS
DAC, ADC, and port assignments are arbitrary; however, ports
are optimized for certain configurations. Use the guidelines in
Table 7, Table 8, and Table 9 when selecting ports for particular
functions. Note the following for each of these tables:
• HP is the output capable of driving headphone load and
power
• MIC is input that supports microphones with MIC Bias
and boost amplifiers
• LO is the line level output
• LI is the line level input
In desktop applications with discreet jacks (the default
configuration), assign the ports as listed in Table 7.
