Subject: [PATCH] ASoC: hdmi-codec: Fix broken channel map reporting
|
|
|
|
Commit b84b53149476b22cc3b8677b771fb4cf06d1d455 upstream.
|
|
|
|
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
|
|
|
|
Switch this back to ca_id in case of PCM audio so the correct channel
|
|
map is reported again and set it to HDMI_CODEC_CHMAP_IDX_UNKNOWN in
|
|
case of non-PCM audio so the PCM channel map control returns "Unknown"
|
|
channels (value 0).
|
