UAUDIO(4) BSD Kernel Interfaces Manual UAUDIO(4)
NAME
uaudio -- USB audio device driver
SYNOPSIS
uaudio* at uhub?
audio* at audiobus?
DESCRIPTION
The uaudio driver provides support for USB audio class devices.
A USB audio device consists of a number of components: input terminals (e.g. USB digital input), output terminals (e.g. speakers), and a
number of units in between (e.g. volume control). The following types of units are handled by the uaudio driver and are accessible via the
mixer (see audio(4)) interface:
mixer A mixer has a number of inputs and one output. Each input has a control that determines its volume in the output. The name
of the control is mixN-S, where N is a number that identifies which mixer it is and S which input.
selector A selector unit selects one of multiple audio sources such as mic-in and line-in. The name of the control is
selN-S1S2S3..., where N is a number that identifies which selector unit it is and the sequence of Sn indicates candidate
units for the audio source.
feature A feature unit changes the sound in some way, like bass, treble, mute, or volume. The name of the control is determined in
a heuristic way. If the unit changes the sound to a speaker output terminal, the names of the controls may be out-
puts.speaker.bass, outputs.speaker.treble, outputs.speaker.mute, outputs.speaker, or likewise.
processing A processing unit does one of a number of audio processing functions (e.g., channel up-down mixing, Dolby ProLogic, or cho-
rus effects). The name of the on-off control is proN.M-enable, where N is a number that identifies which processing unit it
is and M which kind. Depending on the type of processing unit there may be other controls as well.
extension An extension unit performs some unspecified audio processing The name of the on-off control is extN-enable, where N is a
number that identifies which processing unit it is.
For more information the USB Audio class specification is indispensable reading.

HISTORY
The uaudio driver appeared in NetBSD 1.5.
BUGS
There is no support for multiple-endpoints audio stream, adaptive recording, async playback, and TYPE-II/III formats.
There is the possibility that a device has multiple mixer items which have the same name.
