A64 Audio

[Rudolf Streif]

We have a custom board with A64. For audio there is only an amplifier connected to LINEOUT. There is no headphone jack and the HP-DET pin is floating. I enabled the sound device in the device tree and card0 shows up. Tools like aplay show that a sound is being played back but there is no sound. I am suspecting that there is something amiss with the audio routing. The dts is including the sun50i-a64.dtsi. These are the device tree nodes in the board's dts:

&sound {

        simple-audio-card,aux-devs = <&codec_analog>, <&speaker_amp>;

        simple-audio-card,widgets = "Speaker", "Internal Speaker";

        simple-audio-card,routing =

                        "Left DAC", "DACL",

                        "Right DAC", "DACR",

                        "Speaker Amp INL", "LINEOUT",

                        "Speaker Amp INR", "LINEOUT",

                        "Internal Speaker", "Speaker Amp OUTL",

                        "Internal Speaker", "Speaker Amp OUTR",

                        "ADCL", "Left ADC",

                        "ADCR", "Right ADC";

        status = "okay";

};

        speaker_amp: audio-amplifier {

                compatible = "simple-audio-amplifier";

                enable-gpios = <&pio 2 0 GPIO_ACTIVE_HIGH>; /* PC0 AUDIO AMP ENABLE */

                sound-name-prefix = "Speaker Amp";

                status = "okay";

        };

&codec {

        status = "okay";

};

&codec_analog {

        cpvdd-supply = <&reg_eldo1>;

        status = "okay";

};

I cannot see anything obvious incorrect with that. I would appreciate your help.

Thank you,
