    ALSA: usb-audio: Skip volume controls triggers hangup on Dell USB Dock · adcdd0d5

    This is Dell usb dock audio workaround.
    It was fixed the master volume keep lower.
    [Some background: the patch essentially skips the controls of a couple
     of FU volumes.  Although the firmware exposes the dB and the value
     information via the usb descriptor, changing the values (we set the
     min volume as default) screws up the device.  Although this has been
     fixed in the newer firmware, the devices are shipped with the old
     firmware, thus we need the workaround in the driver side.  -- tiwai]
