Minor Revision ID. These bits are read only and will be updated based on minor
device changes which will not require software changes.
Major Revision ID. These bits are read only and will be updated based on major
device changes.
Bits not used, should read back 0
0 = mixer record contains a mix of all mono and stereo analog input signals,
not the DAC (ALL ANALOG mode)
1 = mixer record contains a mix of all mono and stereo analog input signals
plus the DAC signal (AC97 mode)
This bit only has an effect when either Stereo Mix or Mono Mix is selected as
the record source in Reg. 1Ah.
The “ALL” mode is useful in conjunction with the POP BYPASS mode (Reg.
20h;D15) to record all analog sources, perform further processing in the
digital domain, including combining with other PCM data, and routing through
the DACs directly to Line Out, Headphone Out, or Mono Out.
A Stereo Mix recording will be affected by the setting of the 3D Effects bit
(Reg. 20h;D13)
Bits not used, should read back 0
0 = MUTE FIX Enabled
1 = MUTE FIX Disabled
When this bit is zero, and either channel is set to -46.5dB attenuation, 1Fh,
then that channel is fully muted. When this bit is one, then operation is per
AC’97 specification.
