When converting a normal link to a DPCM link we need to set dpcm_playback / dpcm_capture otherwise playback/capture streams will not be created resulting in errors like this:

Hi Daniel,
Typically, for Intel platforms, this information comes from the machine driver and there are some DAI links that have either playback or capture set. But this change would set both for all DAI links. Not sure if this is the right thing to do.
Thanks, Ranjani
