ALSA: usb-audio: Skip volume controls triggers hangup on Dell USB Dock
[ Upstream commit adcdd0d5a1cb779f6d455ae70882c19c527627a8 ]
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]
