When there's need to make a 4ch capture topology would TEST_PDM_ACTIVE be set to 2 and the PDM_TUPLES macro arguments be duplicated with another 0110000 (where the "1" values are mic enables)? Or is this function OK as such to use with any value of TEST_PDM_ACTIVE within HW capability limits and as long as both microphones of a stereo PDM controller are used?
Yes, you would just add the second PDM controller config to the last argument (list of PDM configs) to make a 4ch topology and set the TEST_PDM_ACTIVE accordingly.
Creating a mono single microphone capture topology obviously needs a new test test-capture.m4 macro version.
Thanks, Seppo
