Imaging the following examples: time 1: at the beginning in:-1 in:-1 in:-1 in:-1 out:-1 out:-1 out:-1 out:-1 SIGGEN A B Spk time 2: after someone called snd_soc_dapm_new_widgets() (e.g. create_fill_widget_route_map() in sound/soc/codecs/hdac_hdmi.c) in:1 in:0 in:0 in:0 out:0 out:0 out:0 out:1 SIGGEN A B Spk time 3: routes added in:1 in:0 in:0 in:0 out:0 out:0 out:0 out:1 SIGGEN -----> A -----> B ---> Spk In the end, the path should be powered on but it did not. At time 3, "in" of SIGGEN and "out" of Spk did not propagate to their neighbors because snd_soc_dapm_add_path() will not invalidate the paths if the card has not instantiated (i.e. card->instantiated is false). To correct the state of audio map, recalculate the whole map forcely.
