This page describes how to setup the ALSA sndShare configuration.

Make a .asoundrc file in the users home folder with the following content:
Note: Rename your existing .asoundrc if you have one.

#START of .asoundrc	

#AlSA sound device sharing setup
#Name this file .asoundrc in the home root folder of the user running everything
#Change hw:0,0 to your soundcard device (3 places)
#Change rate to 44100 or 48000 (2 places) - select rate that uses the least cpu
#Set all sound devices to sndShare

#following is optional to make this setup the default
#pcm.!default {
#        type plug
#        slave.pcm "sndShare"
#}
		
pcm.sndShare {
  type plug
  slave.pcm "skypeSound"
  slave.channels 2
  #following mutes sound
  ttable.0.0 0
  ttable.1.1 0

pcm.skypeSound {
         type asym
         playback.pcm "dmix"
