But the thing is, the user= land ALSA API is still asking for S16_LE (observed from the pcm_native.c f= rom kernel) even when I am using SND_PCM_FORMAT_S32_LE in my application co= de as shown in my 1st post. You should try this patch for the twl4030: http://mailman.alsa-project.org/pipermail/alsa-devel/2010-December/034792.h= tml I used aplay/arecord for testing the 32/24 bit support, and it was fine on the twl4030 codec. -- = P=E9ter
