Hi!

/usr/include/alsa/mixer.h contains this comment:

   /* Simple (legacy) mixer elements API */

What does the "legacy" exactly mean? Shouldn't I be using it in new
code? I am currently looking for some way I can find out which PCM
channel for a stream on something like "surround51:0" maps to which
mixer element. How am I supposed to implement something like this
without stuff like the snd_mixer_selem_channel_id_t?

A second question: 

aplay -L suggest to use "surround71:" (and *only* that) as plugin for my
usb webcam that only has a single mono channel.  What's going wrong?
Any idea where I should be looking?

Thanks,

Lennart
