I need to develop a solution to expose to userspace a single sound
card with mixer controls for:
Audio codec : sgtl5000
Audio mux: used to select an audio source on sgtl5000 LINE_IN.
Audio dsp :sta309a
How can I implement this drivers? Should I have to create a sound-card
driver which is going to register and control the other drivers
(codec, mux, dsp)?
Is there some device driver or tutorial guide that I can use as an example?
I'm using the kernel 3.0.15 from Freescale .
