két hanglejátszás egyszerre

Sziasztok!

2 db MP3-lejátszást (pl. mplayerrel) szeretnék az ALSA-val meghajtott hangkártyámon párhuzamosan futtatni úgy, hogy a hangszorón mindkét lejátszást egyszerre halljam. Jelenleg az történik, hogy ha indítok egy második mplayer-t, akkor megvárja, hogy az első befejeződjön, és csak utána kezd játszani (lásd a lenti logot). Lehetőleg sound daemon (pl. ESD, PulseAudio) nélkül szeretném megoldani. Mit javasoltok?

Köszönettel:
