From df68f106436b684520212494a5ce0e3823b485da Mon Sep 17 00:00:00 2001 From: Eldad Zack Date: Sat, 15 Dec 2012 05:30:33 +0100 Subject: [PATCH] ALSA: usb-audio: ignore-quirk for HP Wireless Audio As Joe Cooper 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.
