And the PXA_SSP_DIV_SCR value needed to be doubled from 4 to 8. With that changes, LRCLK is 44100Hz when configured to 44100Hz. But the bitclk is not 64fs anymore but 32fs only (1.41Mhz). Is there any implementation details I miss? What does your codec clock config look like? Another small thing: CC sound/soc/pxa/pxa-ssp.o sound/soc/pxa/pxa-ssp.c:186: warning: 'ssp_get_scr' defined but not used Daniel _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
