D15
Bits D9 – D6 are read only status of the extended audio feature readiness. When a write request is
issued the actual data written into the RAM register is ‘xxxxxx0111xxxxxx’.
For more details refer to AC’97 rev 2.1, section A2.2

In VRA mode, two frequencies are supported 48000 (BB80h) Hz and 44100 (AC44h) Hz. If one of these
values is written to the 2Ch register, that value will be echoed back when read, otherwise the closest
(higher in case of a tie) sample rate supported is returned. The content of the 2Eh and 30h register is
copied from the 2Ch register.
If the Double Rate Audio (DRA) mode is active, the sample rate programmed will be multiplied by 2x. For
example: When running at 88.2KHz, the DRA bit will be programmed to 1, and the sample rate
programmed would be 44.100KHz.
The default value after a cold or warm register reset for these registers is 48kHz, (BB80h). The content of
the sample rate register (32h and 34h) stays always at BB80h.

These read/write registers control the output volume of the optional six I
2
S PCM channels, and values
written to the fields behave the same as the Play Master Volume Register (Index 02h), which offers
attenuation but no gain. There is an independent mute (1=on) for each channel.
The default value after reset for this register (8080h) corresponds to 0dB attenuation with mute on.
