Hi,

Recent asoc change makes S905x audio card prob failed.

[    6.338428] gx-sound-card sound: CPU DAI I2S Encoder for rtd be.dai-link-1 does not support capture
[    6.342176] gx-sound-card sound: ASoC: can't create pcm be.dai-link-1 :-22

Good: 5.7.3
Bad: 5.7.6

After read patches, I find suspect:

https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/sound/soc?h=v5.7.8&id=1bb707fbfd5c246028d76b8f11a19dfd118d6306 

this patch doesn’t allow playback only or capture only dai-link. Why?

BR.
Ning.
