debian testing here, no p*lse, no ja*k, basic soundcard (laptop)
works if another program playing audio is already running (eg. vlc),
I hear two tones at the same time.

If this test program is run with no other program having fun
with audio buffers, I also get:
ALSA lib pcm_dmix.c:1022:(snd_pcm_dmix_open) unable to open slave
Error opening device2.

funny!
