#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.
#
#
#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
