Does it work as is (I don't expect so, > though)? seems to work fine if i specify default:1 as "stereo playback device" in Xine-UI, tested yesterday, well it is a headphone, so it is hard to locate speakers but you get double the volume from parallel speaker drive, 5.1 CH is lower volume ;) for stereo playback we must assure LFE+Center is off, respectively or stereo maybe eliminated acoustically. for Xine it sounds not like, but for VLC, but thats real subjective. the headset has 3 speakers per ear, i dont know the LFE+Center circuits... so plug:surround40 is a good idea. > > For adding the proper configuration, please check the content of > /proc/asound/cards.
