NAME

     snd_uaudio -- USB audio and MIDI device driver

SYNOPSIS

     To compile this driver into the kernel, place the following lines in your kernel configuration file:

	   device sound
	   device usb
	   device snd_uaudio

     Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):

	   snd_uaudio_load="YES"

DESCRIPTION

     The snd_uaudio driver provides support for USB audio class devices and USB MIDI 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 num-
     ber of units in between (e.g. volume control).

     Refer to the 'USB Audio Class Specification' for more information.

BUGS

     The PCM framework in FreeBSD, as of this writing, does not handle device un-registrations in a properly abstracted manner, i.e., a detach
     request is refused by the PCM framework if the device is in use.  It is necessary to allow the device un-registration to complete success-
     fully, otherwise the PCM layer will panic.
