TX2 Asoc with Max98090

I want to add Max98090 driver on TX2 with 28.2.

I used the default codec driver max98088.c, and tegra_t210ref_mobile_rt565x_alt.c as a reference to write the machine driver.

It seems to have succeeded from the log of “dmesg”

I executed the command (amixer -c 1 cset name=“I2S1 Mux” ADMAIF22) and then “aplay -Dhw:1,1 some_audio.wav”, but I can’t hear any sound form Headphone.

I don’t see the ‘nvidia,audio-routing’ property defined in your DT. You need to have something like what was implemented in …

Or is the ‘nvidia,audio-routing’ defined somewhere else as I see …

tegra-snd-t186ref-max98090 sound: ASoC: Add route x HPR -> direct -> x Headphone

In the bootlog.

The following commands do look correct …

Did you mean ADMAIF2 above and not ADMAIF22? ADMAIF22 does not exist. If you meant ADMAIF2, then the above should be fine.

Otherwise you may need to check that the appropriate DAC switches are enabled in the codec. Looking at the driver I see various Left/Right DAC1/2 switches and so you may wish to make sure the DACs are enabled. You can grep throught the mixer controls looking for these.

amixer -c tegrasndt186ref controls | grep DAC

Thank you Jon!

I’m sorry for writting “ADMAIF2” wrong and omitting “audio-routing” of DTB.

I modified “audio-routing” as follow:

nvidia,audio-routing =
//                      "x Headphone",  "x OUT",
//                      "x IN",         "x Mic";
                        "x Headphone",  "x HPR",
                        "x Headphone",  "x HPL";

As you said, the drivers should be fine.

When I used the oscilloscope probe to check the signal of LRCLK, I heared the sound accidentally from headphone. I‘ve tested it many times and gotton the same results.

I think this trouble should lie in the hardware connection of LRCLK.

Thanks again!
