Troubleshooting code:
source/kernel_src/nvidia-oot/sound/soc/tegra/tegra_machine_driver.c
static int add_dai_links(struct snd_soc_card *card)
{
int ret; //发现代码在这里终止,下面的码没有得到执行。
ret = parse_card_info(card, &tegra_machine_pcm_ops,
&tegra_machine_compr_ops);
if (ret < 0)
return ret;
ret = tegra_codecs_init(card);
if (ret < 0)
return ret;
return 0;
}
It is found that the code terminates at the above position, and subsequent code does not seem to be executed. At the same time, dmesg reported the following error:
[ 11.819179] tegra-asoc:: probe of sound failed with error -22
The above code has not completed execution
Regarding the code, I made the following modifications:

question:
Why is the sound node not generated?
