#This asoundrc is for snd_intel8x0 based cards.
#It will allow the following:
#
# upmix stereo files to 5.1 speakers.
# playback real 5.1 sounds, on 5.1 speakers,
# allow the playback of both stere(oupmixed) and surround(5.1) sources at the same time.
#
#
#Certain codecs for this card need certain tweaks
#Please run 'head -1 /proc/asound/card0/codec97#0/ac97#0-0' to find out your codec
#Read any codec specific comments throughout this file.
#
#
#Please try the following commands, to make sure everything is working as it should.
#
# To test stereo upmix : speaker-test -c2 -Ddefault -twav
# To test surround(5.1): speaker-test -c6 -Dplug:surround51 -twav
#
#
#It may not work out of the box for all cards. If it doesnt work for you, read the comments throughout the file.
#If it still doesnt work with your setup, please speak to me (wishie) in #alsa on irc.freenode.net
