Hi,
I want to programm an driver for the Cirrus CS42516. This Codec
communicates with an ARM9 CPU over 3 I2S channels. I want to use 3
stereo channels for playing and two stereo channels for receiving the
data. All three channels are working with the same clock-rate.
I have read the documentation "Writing an Alsa Driver" but I am confused
about the meaning of PCM Streams and Substreams. What must I declare,
one PCM Stream with three Substreams or 3 PCM Streams ?
Is there any existing driver with a similar configuration (more than one
channel)?
Thanks
Klaus
