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 >=20 > Could the many dai links feature support this case?=20 As Jyri said: why not two simple-cards? > I my understanding is correct here, this patch will support the > Board, in which board there maybe only one CODEC supporting many > DAIs... The audio (platform) device of my machine has two outputs (I2S and S/PDIF =3D 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. --=20 Ken ar c'henta=C3=B1 | ** Breizh ha Linux atav! ** Jef | http://moinejf.free.fr/
