#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.
