to figure it out. If you need to specify an ALSA device somewhere, make

mixing.
Slight correction/expansion -- don't do _software_ mixing. Some cards can do
hardware mixing and in that case, "hw:N" or, specifically "hw:N,0", "hw:N,1"
and so on devices are available as hardware mixed devices.
Try a cat /proc/asound/card0/pcm0p/info and check the "subdevices_count" for
the number of hardware mixed playback devices you have available. If it's 1,
your card should've been configured (by ALSA itself) to use software mixing
by default and if it's higher than 1, it should not have been and will use
hardware mixing...
