I think you are hitting same problem as mentioned in

WM8904 audio driver support for Jetson TX2 NX

I have now added these to tegra_machine_driver_mobile.c and the error has been resolved. static int tegra_machine_wm8904_init(struct snd_soc_pcm_runtime *rtd) { struct device *dev = rtd->card->dev; int err; err = snd_soc_dai_set_sysclk(rtd->codec_dai, WM8904_CLK_MCLK, 12288000, SND_SOC_CLOCK_IN); if (err) { dev_err(dev, “failed to wm8904 sysclk!\n”); return err; } return 0; } static int codec_init(struct tegra_machine *machine) { struct snd_soc_dai_link *dai_links = machine->asoc…

Try with the “WM8904_CLK_MCLK” clock in machine driver at the place of “WM8904_CLK_AUTO” like here it is done:
