Subject: [PATCH] FROMLIST(v1): ASoC: hdmi-codec: reorder channel allocation list
|
|
|
|
Wrong channel allocation is selected by hdmi_codec_get_ch_alloc_table_idx().
|
|
|
|
E.g when ELD reports FL|FR|LFE|FC|RL|RR or FL|FR|LFE|FC|RL|RR|RC|RLC|RRC
|
|
|
|
ca_id 0x01 with speaker mask FL|FR|LFE gets selected instead of
|
|
ca_id 0x03 with speaker mask FL|FR|LFE|FC for 4 channels
|
|
|
|
and
|
|
|
|
ca_id 0x04 with speaker mask FL|FR|RC gets selected instead of
|
|
ca_id 0x0b with speaker mask FL|FR|LFE|FC|RL|RR for 6 channels
|
|
|
|
Fix this by reorder the channel allocation list with
|
|
most specific speaker mask at the top.
