Get Output/Input (GOI): This bit controls whether the request is for
the input amplifier or the output amplifier. When ‘1’, the output amplifier
is being requested. When ‘0’, the input amplifier is being requested.
‘0’b
Get Left/Right (GLR): This bit controls whether the request is for the
left channel amplifier or the right channel amplifier. When ‘1’, the left
channel amplifier is being requested. When ‘0’, the right channel ampli-
fier is being requested.
Reserved
Index (IDX): This field specifies the input index of the amplifier setting
to return if the widget has multiple input amplifiers. It is only applicable
if “Get Output/Input” is ‘0’ which indicates input amplifier is being
requested. This field has no meaning and ignored since the widget
does not have multiple input amplifiers. It should be always ‘0’s.

Amplifier Mute (AM): This bit returns the Mute
setting for the amplifier requested. A 1 indicates
the amplifier is in the Mute condition. If the ampli-
fier requested does not exist, a ‘0’ will be
returned. Default equals Muted.
Amplifier Gain (AG): This field returns the Gain
setting for the amplifier requested. If the amplifier
requested does not exist, all ‘0’s will be returned
Default equals 0 dB.
Set Output Amplifier (SOA): Determines if the
value programmed refers to the output amplifier.
Set to a 1 for the value to be accepted.
