I agree, that looks relevant:
[ 4849.250374] Audio Port: ASoC: no backend DAIs enabled for Audio Port
which comes from the kernel, sound/soc/soc-pcm.c:
/* there is no point preparing this FE if there are no BEs */
if (list_empty(>dpcm[stream].be_clients)) {
dev_err(fe->dev, "ASoC: no backend DAIs enabled for %s\n",
fe->dai_link->name);
ret = -EINVAL;
goto out;
}
