It looks like there is an incomplete audio path from Mic1 --> ADC, hence DAPM will power down all unused components. Fwiw, I have captured from WM9713 Mic1 in the past on Mainstone. Machine driver is here for reference :- http://opensource.wolfsonmicro.com/cgi-bin/gitweb/gitweb.cgi?p=linux-2.6-asoc;a=blob;f=sound/soc/pxa/mainstone_wm9713.c;h=65c6517e60bc88478796c67fbbfe9c2243c14a88;hb=dev Can you post your machine driver. It may help with debugging. Liam _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
