Hi Mark

Can I confirm about this ?

If my understand is correct,
current upstream code doesn't have above feature at this point,
and, I can update DPCM feature for it ?

If yes, and if I want to exchange rate from 96kHz -> 48kHz,
I can use be->dai_link->be_hw_params_fixup() for 48kHz settings ?

Then, FE side want to know this result (= BE want to use 48kHz).
I can add something new method for it ?

Or does current upstream code already have something this feature ?

Best regards
