Are you using the CQ0093VC driver to communicate with the ICS-43432, but no actual CQ0093VC codec then? That won't work. The ICS-43432 basically uses 64 bits per frame, with 24 valid bits per channel, i.e. S24_LE or S32, whereas the CQ0093VC seems to only support the U8 or S16_LE formats. There might be another codec driver which is more suitable, but it makes the most sense to use the ICS-43432 driver as it is intended for the hardware in question. /Ricard -- Ricard Wolf Wanderlöf ricardw(at)axis.com Axis Communications AB, Lund, Sweden www.axis.com Phone +46 46 272 2016 Fax +46 46 13 61 30 _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
