Hi,

I am working on an imx8mn-based board with an ES9080 codec and I am trying to get EASCR to work. (The ES9080 driver is not upstreamed yet).

Audio playback works fine via simple-audio-card and here are my changes to get EASRC to work:

- sound-ess { - compatible = "simple-audio-card"; - simple-audio-card,name = "ess-audio"; - simple-audio-card,format = "left_j"; - simple-audio-card,frame-master = <&s2cpu>; - simple-audio-card,bitclock-master = <&s2cpu>; - - s2cpu: simple-audio-card,cpu { - sound-dai = <&sai2>; - dai-tdm-slot-num = <8>; - dai-tdm-slot-width = <32>; - }; - - simple-audio-card,codec { - sound-dai = <&es9080>; - }; + sound-es9080 { + compatible = "fsl,imx-audio-es9080"; + model = "es9080-with-easrc"; + audio-cpu = <&sai2>; + audio-codec = <&es9080>; + audio-asrc = <&easrc>; }; };

The es9080-with-easrc card is registered, but after running 'speaker-test' no audio output is present.

Is there a way to use the EASRC driver with the simple-audio-card without touching fsl-asoc-card.c? That would be preferable.

Would you have any suggestions as to what may be missing to get EASRC to work?

Thanks,
