SGTL5000 with imx6 sololite - Line out not working

[jagsgediya]

Hi All,

We are using sgtl5000 audio codec from the freescale with the imx6 sololite processor.

We are able to get mic and headphone working but speaker on line out is not working. We are using the existing machine and codec driver available in kernel 3.10.17 of yocto 1.6.

We have taken refrence for device tree changes from the sabrelite board device tree file.

Drivers:

sound/soc/fsl/imx-sgtl5000.c

sound/soc/codecs/sgtl5000.c

Device tree changes:

sound {	/* Read related .txt file in Documentation for binding */
	compatible = "fsl,imx6sl-alba-sgtl5000",
	"fsl,imx-audio-sgtl5000";
	model = "imx6sl-alba-sgtl5000";
	ssi-controller = <&ssi2>;
	audio-codec = <&codec>;
	audio-routing =
	"MIC_IN", "Mic Jack",
	"Mic Jack", "Mic Bias",
	"Headphone Jack", "HP_OUT",
	"Line Out Jack", "LINE_OUT";
	mux-int-port = <2>;
	mux-ext-port = <3>;
	};

But, unfortunately the speaker on line out is not working. Can anyone have got line out port working with sgtl5000?

Or anything i am missing?

Thanks,

Jags

I was about to go crazy with sound not working with line out and found the answer here to work. Thank you alejandrolozano!

for anyone using imx35 and sgtl5000 with linux-fslc : below is my dts content:

sound {
compatible = "fsl,imx-audio-sgtl5000";
model = "ebox-sgtl5000";
ssi-controller = <&ssi1>;
audio-codec = <&codec>;
audio-routing =
"MIC_IN", "Mic Jack",
"Mic Jack", "Mic Bias",
"Headphone Jack", "HP_OUT",
"Ext Spk", "LINE_OUT";
mux-int-port = <1>;
mux-ext-port = <4>;
};

codec: sgtl5000@0a {
compatible = "fsl,sgtl5000";
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_sgtl5000>;
reg = <0x0a>;
clocks = <&clks 86>;
VDDA-supply = <&vcam_reg>;
VDDIO-supply = <&reg_sgtl5000_vddd>;

};

Hi,

Can you try this

Ext Spk", "LINE_OUT";

Instead of 

"Line Out Jack", "LINE_OUT";

Please let me know the results.

Why cannot use "Line Out Jack", "LINE_OUT"; ?

Is this based on which pin I design to be LINE_OUT?
