I need feedback from you, it is still not clear for me.
But I noticed that we want to update below. I'm happy if it can solve your
issue.
- if (has_playback && !has_playback_both)
+ if (has_playback && !has_playback_both && !dai_link->capture_only)
dev_warn(rtd->card->dev, ...)
- if (has_capture && !has_capture_both)
+ if (has_capture && !has_capture_both && !dai_link->playback_only)
dev_warn(rtd->card->dev, ...)
Thank you for your help !!
Best regards
