Check that all the required DAPM widgets are powered up by looking in /sys/bus/platform/devices/soc-audio/dapm_widget during playback - if they aren't then enabling DAPM_DEBUG in sound/soc/soc-dapm.c will make DAPM display information about the decisions it's making. If you can't see anything there could you please supply a register dump from during playback (availible in /sys/bus/platform/devices/soc-audio/codec_reg)?
