so if understand, a single audio stream is coming from the software mixer,
which mixes multiple stream from different sources, and transfered using the
PCM interface to th kernel and then to the hardware ? the software mixing in
alsa is done by dmix i guess ?

Hi
Kinda new to linux audio and still a bit new to dev generally and I'm
trying to understand the basis of linux audio.
By that, I mean the ALSA API :
I would like to use the PCM interface and the mixer interface to mix 2
sounds
the mixer interface does not do that. its an API to control the hardware
mixer (if any) present in the audio interface hardware. a lot of current
audio interface hardware is incapable of mixing sound from multiple
sources, so this is generally done in software.
