ALSA: usb-audio: ignore-quirk for HP Wireless Audio
As Joe Cooper <swelljoe@gmail.com> reported, "On most HP Envy laptops the snd-usb-audio module causes the system to become unresponsive and Gnome Shell 3 to crash.". See also: http://mailman.alsa-project.org/pipermail/alsa-devel/2012-December/057729.html Add a quirk to ignore this device (for now) to solve the instability issue and allow other USB audio devices to be used.
