== Kodi 14.0 Helix note == | |||
It appears that in KodiBuntu 14.0 Helix with default ALSA config, attempting to play 6-channel AAC audio over HDMI no longer results in a 6-channel LPCM passthrough with incorrect mappings. Instead, it appears to end up as 6-channel LPCM non-passthrough with correct mappings. I guess Kodi's AudioEngine is performing the remapping for us, which is probably a good thing. | |||
This means that my Frodo .asoundrc in the article is no longer needed for Kodi itself. However, speaker-test shows that the ALSA-level mappings are still wrong, so remapping is still needed if you plan to use 6+ channel audio in non-Kodi apps. In this case, you can probably just configure Kodi to use hdmi_hw or some other untouched output. | |||

Some XBMCbuntu 12.0 Frodo official release version notes
- 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.
