SND_UAUDIO(4) BSD Kernel Interfaces Manual SND_UAUDIO(4)NAMEsnd_uaudio -- USB audio device driverSYNOPSISTo 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"DESCRIPTIONThe snd_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 num- ber of units in between (e.g. volume control). Refer to the 'USB Audio Class Specification' for more information.SEE ALSOsound(4), usb(4) USB Audio Class Specifications, http://www.usb.org/developers/devclass_docs/.HISTORYThe snd_uaudio driver first appeared in FreeBSD 4.7.AUTHORSThis manual page was adopted from NetBSD 1.6 and modified for FreeBSD by Hiten Pandya <hmp@FreeBSD.org>.BUGSThe 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. For USB and supposedly other detach-able busses, it is necessary to allow the device un-registration to complete successfully, otherwise the driver leaves wild pointers to invalid data structures and thus leading to a panic.BSDDecember 15, 2005 BSD
