HI Pierre.
Thanks for your response,
Yes I meant for ASoC core, We will check your patch and update.

HI All,
We see get_time_info is not enabled from ALSA core. ay reason behind?
I think you meant ASoC core?
we enabled like below with some more code, we are able to get_time_info to lower driver.

Is this ALSA limitation or any other approach is followed to enable this implementation.
No, it's a miss.
I had a patch to fix this in https://github.com/thesofproject/linux/pull/3792, but somehow it never made its path upstream. I don't fully recall the details, only vaguely that we first added support for the .delay(), but the get_time_info part was tested back in August 2022.
Would that patch work for you?
