to figure it out. If you need to specify an ALSA device somewhere, make
sure it's not the old "hw:0" but "default" (or "default:0" for the
first card, "default:1" for the second, ...). The "hw:N" devices don't
do 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.

Correcting the correction (sorry, it was late) -- "hw:N" is card N, "hw:N,M" is PCM interface M of card N and "hw:N,M,K" is (hardware mixed) subdevice K on PCM interface M of card N. Normal cards have only one PCM interface meaning that M is 0 in the above.

That is, I meant that "hw:N,0,0", "hw:N,0,1" and so on are the hardware mixed devices.
