Interface #0
Interface #0 is the control interface. Alternative setting #0 is the only possible setting for interface #0. Alternative
setting #0 describes the standard audio control interface. The audio control interface is constructed by a
terminal. The PCM2904/2906 has the following five terminals.
Input terminal (IT #1) for isochronous-out stream
Output terminal (OT #2) for audio analog output
Feature unit (FU #3) for DAC digital attenuator
Input terminal (IT #4) for audio analog input
Output terminal (OT #5) for isochronous-in stream
Input terminal #1 is defined as a
USB stream
(terminal type 0x0101). Input terminal #1 can accept 2-channel
audio streams consisting of left and right channels. Output terminal #2 is defined as a
speaker
(terminal type
0x0301). Input terminal #4 is defined as a
microphone
(terminal type 0x0201). Output terminal #5 is defined
as a
USB stream
(terminal type 0x0101). Output terminal #5 can generate 2-channel audio streams consisting
of left and right channels. Feature unit #3 supports the following sound control features.
Volume control
Mute control
The built-in digital volume controller can be manipulated by an audio-class-specific request from 0.0 dB to
–64 dB in steps of 1 dB. Each channel can be set for different values. The master volume control is not
supported. A request to the master volume is stalled and ignored. The built-in digital mute controller can be
manipulated by audio-class-specific request. A master mute control request is acceptable. A request to an
individual channel is stalled and ignored.
Interface #1
Interface #1 is the audio streaming data-out interface. Interface #1 has the following seven alternative settings.
Alternative setting #0 is the zero-bandwidth setting. All other alternative settings are operational settings.
