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.

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...
