Hi Mark and Takashi,
In kernel 2.6.34 I can use aplay to play audio at the same time, alsa will mix the audio.
No, kernel part doesn't do such a thing. If it's mixed, it must be in the user-space (either dmix or a daemon like pulseaudio), unless you hardware can do mixing by itself.
Now the second open will return device busy.
So, something else must have been changed in your system...
