• HDMI setup using ~/.asoundrc

  Date: 2010.08.10 | Responses: 0

  This .asoundrc file sets the hdmi digital audio output as the default sound output device. The sweet thing about this setup is that it uses the dmix plugin, allowing you to have multiple applications use the device at once instead of just one hogging it. Also, this will add a volume slider to your mixer (hdmi_vol). Thanks to  the original person who wrote the config, Dewey Oxberger (aka Jon B), and  frigginacky at ubuntu forums (see post).
  Note: To find the device card & number, you can run

  aplay -l

  ~/.asoundrc file:

  pcm.hdmi_formatted {
   
    type plug
   
    slave.pcm "dmix:1,3" #card 1, device 3 (may be different for you)
   
  }
   
  pcm.hdmi_complete { # add a volume slider in mixer
   
    type softvol
   
    slave.pcm hdmi_formatted
   
    control.name hdmi_volume
   
    control.card 0
   
  }
   
  pcm.!default hdmi_complete
