Hello,

I am trying to set the sound system using "simple-audio-card" and TLV320AIC23B audio codec in Compulab CM-510 SoM.

This is my structure in DT, according to ./KERNEL/Documentation/devicetree/bindings/sound/simple-card.txt, /KERNEL/Documentation/devicetree/bindings/sound/widgets.txt and the source code of the audio-codec ./KERNEL/sound/soc/codecs/tlv320aic23.c :

  sound {
                 compatible = "simple-audio-card";
                 simple-audio-card,name = "OnboardTLV320AIC23B";
                 simple-audio-card,format = "i2s";
                 simple-audio-card,bitclock-master = <&dailink_master>;
                 simple-audio-card,frame-master = <&dailink_master>;
                 simple-audio-card,widgets =
                         "Microphone", "Mic Input",
                         "Line", "Line Input",
                         "Line", "Line Out",
                         "Speaker", "Speaker",
                         "Headphone", "Headphone Jack";

                 simple-audio-card,routing =
                         "Line Out", "LOUT",
                         "Line Out", "ROUT",
                         "Line Out", "RHPOUT",
                         "Line Out", "LHPOUT",
                         "LLINEIN","Line Input",
                         "RLINEIN","Line Input",
                          "MICIN","Mic Input";
                 simple-audio-card,cpu {
                                 sound-dai = <&audio0 0>;
                         };
                 dailink_master: simple-audio-card,codec {
                                 sound-dai = <&opt_audio>;
                         };
                 };
};

/* TLV320AIC23 */

&opt_audio {
             status = "okay";
             #sound-dai-cells= <0>;

};

And this is the kernel trace:

...

...

[....] Setting up ALSA...amixer: Invalid command!
...

I think I have written the node according to the documentation, but probably I miss something.
Anyone has faced a similar problem?

I would really appreciate some kind of help.

Thank you,

Gabriel

Hi Gabriel,

I think that the lack of space in all three input routings can make a difference. Please let know if adding it helps.

Best regards,
Marcin

Gabriel,

you should try to add people and lists you expect help from.

Looking at sound/soc/codecs/tlv320aic23.c:

	/* input mux */
	{"Capture Source", "Line", "Line Input"},
	{"Capture Source", "Mic", "Mic Input"},
	{"ADC", NULL, "Capture Source"},

};

The lines with the failing routes really look suspicious, i.e. there is strings "NULL" where I'd expect plain NULL.

What happens if you amend the three lines and replace the "NULL" with NULL?

Marcin,

Thank you for your answer!. It seems that space does not matter (I have checked it), but yes, it is necessary to be careful with this kind of things..

Sebastian,

You were right, as always :) , I have changed them and now errors are not reported. Now, in the boot trace I find:

...

...

...
ALSA device list:
#0: OnboardTLV320AIC23B
...

but after rootfs is up, this msg appears in dmesg:

platform sound: Driver asoc-simple-card requests probe deferral

In reference to the card, I get the following info:

root@192:~#cat /proc/asound/cards

Mind to send a proper patch fixing the above? Make sure you run ./scripts/checkpatch.pl and ./scripts/get_maintainer.pl on the patch. It should give you an idea of proper code style and what people/lists to send it to. I am sure, google will help you with how to prepare proper kernel patches, too.

but after rootfs is up, this msg appears in dmesg:
platform sound: Driver asoc-simple-card requests probe deferral

This is, as always, a missing dependency of simple-card node.

Either you are missing drivers for Dove audio (kirkwood-i2s) or one of the drivers involved in your simple-card fails.

Look for errors in your dmesg output - also please name the kernel version you are working with. There have been some changes in clk handling that break a bunch of drivers in 4.0-rc1.
