[alsa-devel] [PATCH][INFO]: linux/sound/usb/ : add special settings for M-Audio Fast Track Pro and Quattro (24 bits, etc...)

!! ALREADY APPLIED BY TAKASHI IWAI ON LINUX 3.1 !!

This patch built against Linux 2.6.39 gives M-Audio Fast Track Pro and M-Audio Quattro quirks and endpoints to boot and setup those devices with special options (digital inputs and outputs, 24 bits mode, etc...). M-Audio Audiophile quirks are just adapted to match the new global M-Audio parameters.

Special configurations can be then loaded through a modprobe conf file. For example, to set the 24 bits mode on the Fast Track Pro add /etc/modprobe.d/fast_track_pro.conf :

options snd_usb_audio vid=0x763 pid=0x2012 device_setup=0x08 index=1 enable=1

Here is a list of the possibilities in this example : http://files.parisson.com/debian/fast-track-pro.conf

Enjoy, Cheers Alsa Team ;) Guillaume
