I followed the following guide: http://forum.xbmc.org/showthread.php?tid=96138

Here is the results of $ aplay -l:

Code:

$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: Generic [HD-Audio Generic], device 3: HDMI 0 [HDMI 0]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 1: Generic_1 [HD-Audio Generic], device 0: ALC269VB Analog [ALC269VB Analog]
  Subdevices: 0/1
  Subdevice #0: subdevice #0

From this output I have discovered that my following devices are:
HDMI -> hw:0,3
Analog -> hw:1,0

I need to output sound to both devices. In the settings within XBMC there is only the option of HDMI or Analog under "Audio Device Output".

Here is my .asoundrc file:

Code:

$ cat .asoundrc
#----
# .asoundrc file designed to expand 2 channels through device 'clone_output'
# to output 2 channels to multiple devices
#
# caveats : no mixed output (no crossfading, no multiple applications) also
# sync will drift between the devices (rarely do i see mine drift though)
#
# designed around a nvidia ION1 zotac board. You may need to change
# device names.
# Use aplay -l to find device numbers
#
# questions contact Loto_Bak on forums.xbmc.org

    type plug
    slave.pcm "dmixed_hdmi"
    }

# Single channel dmixed. Crossfade works

pcm.hdmiout {
    type plug
    slave.pcm "dmixed_hdmi"
}

pcm.dmixed_hdmi {
    type dmix
    ipc_key 2024
    slave {
        pcm "hw:0,3" # hdmi
        }

pcm.clone_output {
    type plug
    slave.pcm "6channel_expander"
        }
        
pcm.multi_pcm_device {
        type multi;
        slaves.a.pcm "hw:0,3"; # hdmi
        slaves.a.channels 2;
        slaves.b.pcm "hw:1,0"; # analog

        bindings.4.slave c;

    bindings.5.slave c;
        bindings.5.channel 1;
}
ctl.multi_pcm_device {
        type hw;
        card 0;
}
pcm.6channel_expander {
        type route;
        slave.pcm "multi_pcm_device";
        slave.channels 6;
        ttable.0.0 1;
        ttable.1.1 1;
        ttable.0.2 1;

        ttable.0.4 1;
        ttable.1.5 1;
}
ctl.6channel_expander {
        type hw;
        card 0;
}

However, when I reboot the box the sound is only coming out of one of the devices still, and I can only select one device at a time.

I was able to get this to work using pulseaudio's $ pacmd load-module module-combine within the xbmcbuntu side of the box.

Current versions of xbmc no longer output sound over two devices. It may come in future releases as AudioEngine matures, but no timetable available at this time.

That is contrary to the other threads showing that people that have frodo and multiple audio sources. I just don't know how to make chanes to the .asoundrc file.
