From ae8416e23a9566e6a1f6f37b7fc65914a125da24 Mon Sep 17 00:00:00 2001 From: Matthias Reichl Date: Sat, 9 Sep 2023 13:46:33 +0200 Subject: [PATCH] ASoC: hdmi-codec: Fix broken channel map reporting Commit 4e0871333661 ("ASoC: hdmi-codec: fix channel info for compressed formats") accidentally changed hcp->chmap_idx from ca_id, the CEA channel allocation ID, to idx, the index to the table of channel mappings ordered by preference. This resulted in wrong channel maps being reported to userspace, eg for 5.1 "FL,FR,LFE,FC" was reported instead of the expected "FL,FR,LFE,FC,RL,RR": ~ # speaker-test -c 6 -t sine ... 0 - Front Left 3 - Front Center 1 - Front Right 2 - LFE 4 - Unknown 5 - Unknown ~ # amixer cget iface=PCM,name='Playback Channel Map' | grep ': values' : values=3,4,8,7,0,0,0,0 Revert this incorrect change so that channel maps are properly reported again.
