Audio Applications Might Stop Working After a USB Audio Device Is Hot-Unplugged (4424286)

If you hot-unplug a USB audio device the links to /dev/audio are broken. As a result, some audio applications might not recognize audio devices, including on-board audio. Rebooting the system or hot-plugging the USB audio device has no effect.

Workaround: Perform the following steps after a USB audio device is hot-unplugged.

  1. Become superuser.

  2. Correct the broken links by typing the following on a command line.

    # rm /dev/audio*
    # /usr/sbin/devfsadm -c audio
