In my machine, there is only one audio device and the CODECs don't need any format, sysclk or TDM slot. But, as Jyri asked it too, I will add these properties. > On my LS1 platform there are two CODECs and two CPU SAI deivces, > SGTL5000 <---> SAI > CS42888 <---> ESAI > > Could the many dai links feature support this case?

The audio (platform) device of my machine has two outputs (I2S and S/PDIF = CPU DAIs) which are connected to different CODECs (HDMI transmitter and S/PDIF connector). There must be two different HDMI CODECs because the format and rate constraints of the wires (I2S and S/PDIF) are different. There is only one playback stream. -- Ken ar c'hentañ | ** Breizh ha Linux atav! ** Jef | http://moinejf.free.fr/
