Hi all,
I am trying how a non-BE link is converted to a BE link inside soc_check_tplg_fes.
soc_check_tplg_fes => for all components that have ignore_machine setup to card name => dai_link->platforms->name = component->name; => dai_link->no_pcm = 1;
But the thing is that the link is a true non-DPCM link, than fields like dpcm_playback/dpcm_capture are not set and playback/record substreams are no created.
These fields should be being populated by topology since they are runtime configuration on a non DPCM PCM device.
The question is: is this supposed to be working with non-DPCM links?
Yes, it "should do" and did when I last tested - there were some non DPCM Intel machine drivers that needed to work (grep -L no_pcm sound/soc/intel/boards/*.c), but I am not as up to date as other on the SOF driver core now. So if it's not working, it could be a regression (as these non DPCM boards are not used now IIRC).
