7.1+2 Channel HD Audio Codec with Content Protection
31
Track ID: JATR-2265-11
Rev. 1.2
8.1.10. Parameter – Amplifier Capabilities
(Verb ID=F00h, Input Amplifier Parameter ID=0Dh)
Parameters in this node provide audio function group default information. Individual converters have
their own parameters to provide amplifier capabilities if the ‘AMP Param Override’ bit is set.
