This procedure assumes that you have already connected the USB audio devices.
Examine your system's new audio links.
Display your system's new audio links with the ls command.
For example:
% ls -lt /dev/audio* lrwxrwxrwx 1 root root 7 Jul 23 15:46 /dev/audio -> usb/audio0 lrwxrwxrwx 1 root root 10 Jul 23 15:46 /dev/audioctl -> usb/audioctl0/ % ls -lt /dev/sound/* lrwxrwxrwx 1 root root 74 Jul 23 15:46 /dev/sound/1 -> ../../devices/pci@1f,4000/usb@5/hub@1/device@3/sound-control@0:... lrwxrwxrwx 1 root root 77 Jul 23 15:46 /dev/sound/1ctl -> ../../devices/pci@1f,4000/usb@5/hub@1/device@3/sound-control@0:... lrwxrwxrwx 1 root other 66 Jul 23 14:21 /dev/sound/0 -> ../../devices/pci@1f,4000/ebus@1/SUNW,CS4231@14,200000:sound,audio lrwxrwxrwx 1 root other 69 Jul 23 14:21 /dev/sound/0ctl -> ../../devices/pci@1f,4000/ebus@1/SUNW,CS4231@14,200000:sound,audioctl % |
Notice that the primary audio device, /dev/audio, is pointing to the newly plugged in USB audio device, /dev/usb/audio0.
You can also examine your system's USB audio devices with the prtconf command and look for the USB device information.
% prtconf . . . usb, instance #0 hub, instance #0 mouse, instance #0 keyboard, instance #1 device, instance #0 sound-control, instance #0 sound, instance #0 input, instance #0 . . . |
