Hi!
Any ideas?
You probably did not enable the soundcard driver, that binds against "audio-graph-card" compatible and connects the codec driver with the SoC driver: CONFIG_SND_AUDIO_GRAPH_CARD
Ok, that certainly changed things; I am now getting this:
Mar 23 08:39:17 devuan kernel: [ 11.633605] asoc-audio-graph-card soundcard: GPIO lookup for consumer pa Mar 23 08:39:17 devuan kernel: [ 11.644958] asoc-audio-graph-card soundcard: using device tr ee for GPIO lookup Mar 23 08:39:17 devuan kernel: [ 11.656677] of_get_named_gpiod_flags: can't parse 'pa-gpios' property of node '/soundcard[0]' Mar 23 08:39:17 devuan kernel: [ 11.669738] of_get_named_gpiod_flags: can't parse 'pa-gpio' property of node '/soundcard[0]' Mar 23 08:39:17 devuan kernel: [ 11.682617] asoc-audio-graph-card soundcard: using lookup ta bles for GPIO lookup Mar 23 08:39:17 devuan kernel: [ 11.694427] asoc-audio-graph-card soundcard: lookup for GPIO pa failed
That's not an error, but just some debug messages. Consider disabling CONFIG_DEBUG_GPIO to get rid of them.
Indeed the dts does not seem to contain any gpios
It's optional and does not exist on Droid 4.
soundcard { compatible = "audio-graph-card"; label = "Droid 4 Audio"; simple-graph-card,widgets = "Speaker", "Earpiece", "Speaker", "Loudspeaker", "Headphone", "Headphone Jack", "Microphone", "Internal Mic"; simple-graph-card,routing = "Earpiece", "EP", "Loudspeaker", "SPKR", "Headphone Jack", "HSL", "Headphone Jack", "HSR", "MICR", "Internal Mic"; dais = <&mcbsp2_port>, <&mcbsp3_port>;};
Any more ideas? :-)
Make sure, that the device was not proped properly (cat /proc/asound/cards) and post the real error? :)
Unfortunately, that are last messages from asoc-audio-graph-card
Mar 23 08:39:17 devuan kernel: [ 11.694427] asoc-audio-graph-card soundcard: lookup for GPIO pa failed
and no, it is not detected:
root@devuan:/home/user# cat /proc/asound/cards 0 [H58006000encode]: HDMI_58006000_e - HDMI 58006000.encoder HDMI 58006000.encoder root@devuan:/home/user#
Hmm. Is it possible that EPROBEDEFFER is playing with me again?
