Hi Morimoto-san, In simple-card.c simple_get_dais_count function there is this comment: * ex1) * CPU0 --- Codec0 * CPU1 --- Codec1 * CPU2 -----/ * CPU3 --- Codec2 * * => 5 links = 2xCPU-Codec + 2xCPU-dummy + 1xdummy-Codec * => 7 DAIs = 4xCPU + 3xCodec * => 1 ccnf = 1xdummy-Codec So, I don't understand exactly how did you get the formula for links. AFAICT there should be 3 x CPU-Codec + 1 x CPU-dummy. thanks, Daniel. _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx https://mailman.alsa-project.org/mailman/listinfo/alsa-devel
