[alsa-devel] [ASoc] TDM over one SSC channel on AT91 possible?

[Jason Fox]

Hello everyone,

I am looking for some help where I need an AD193X codec to be shared
between 8 audio streams using one SSC channel on an AT91SAM9263, in
other words, I need it to look like 8 different soundcards.  We have the
8 TDM channels working in the driver but I can't figure out how to
create the proper interface of 8 soundcards for ALSA.  In an earlier
email in this topic was posted:

I think that maybe that I want to instantiate one driver with 8 pcms.  Where/how do I
instantiate the PCMs?  I guess it in in the machine driver?

This is our first attempt at developing a Linux based system so please forgive my 
newbie question.  I am sure this is really simple but I'm not following somewhere.

Thanks for your help,
