Okay, no pulseaudio.

This reference says you get dmix by default
for ALSA, version above 1.0.9rc2. So several
years.

http://alsa.opensrc.org/Dmix

You also want to make sure there is no asoundrc.

Probably you will get better help if you post
to Linux Audio Users mailing list.

It may help to know the output of

lspci

cat /proc/asound/cards

lsmod | grep snd


Hope this helps
