From df68f106436b684520212494a5ce0e3823b485da Mon Sep 17 00:00:00 2001 From: Eldad Zack Date: Sat, 15 Dec 2012 05:30:33 +0100 Subject: 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.

Full duplex support is provided, i.e. playback and recording in stereo. The format is hardcoded at 48000Hz @ 24 bit, which is the maximum that the device supports. Also, MIDI in and MIDI out both work. Users will notice that the S/PDIF light also flashes when playback or recording is active. I believe this means that S/PDIF input/output is simultaneously activated with the analogue i/o during use. But this particular functionality remains untested. Note that this particular version of the patch is so far untested on the physical hardware because I have not compiled a full kernel with the changes. However, extensive testing has been done by many users of the hardware who believe other versions of my patch have worked since circa 2009.
