It contains two basic operations: - setup the CA(channel-allcation) byte in the audio infoframe - setup the converter channel to HDMI slot mapping Please check the last two patches for the detailed descriptions: [PATCH 1/4] hda: make standalone hdmi_fill_audio_infoframe() [PATCH 2/4] hda: make global snd_print_channel_allocation() [PATCH 3/4] hda: HDMI channel allocations for audio infoframe [PATCH 4/4] hda: HDMI channel mapping cleanups The current implementation only does minimal works that can ensure the multi-channel audio playing out. However the wrong speakers may be choosed, and I really need more information/knowledge/instructions from you to get it right. Thank you, Fengguang --
