HOW-TO talk:Remap HDMI audio on Gen 1 ION - Linux

Some XBMCbuntu 12.0 Frodo official release version notes: --HunterZ 14:44, 2 February 2013 (EST)
 * In "Audio output = HDMI" mode, "Passthrough output device" is NOT used for some reason. Instead, only "Audio output device" is used for everything (including menu sounds).
 * Here is an .asoundrc that better accommodates desktop application usage in XBMCbuntu, by setting up an ALSA dmix plugin by default: http://forum.xbmc.org/showthread.php?tid=90910&pid=1320755#pid1320755
 * I don't think that Gen 1 ION is able to passthrough AAC over HDMI. XBMC seems to implicitly convert to LPCM when it can, or AC3 as the second choice.
