I am new in linux. My question is where is the CODEC
plug-in, I can plug in different codec of my own in
the ALSA. Where is the digital mixing and sample rate
conversion in the ALSA?
Is there any complete design doc for the ALSA? So, I
can see the control flow top-down.
Thanks

These live in userspace. Mixing is handled by dmix, SRC by the plughw
plugin. See the alsa-lib distribution.

Not exactly. But this document should give a pretty good idea of the
control flow when using a PCM.
