I tried to run Openwengo in a 64 bit laptop with Gentoo. After fixing tipical shared libraries issues, the program runs but it detects no sound card. Downloading a 32 bit aplay command shows that this is a problem of ALSA 32 bit applications (64 bit aplay works fine). Trying to run 32 bit aplay shows these messages: > ./aplay /usr/share/sounds/alsa/Front_Right.wav ALSA lib confmisc.c:560:(snd_determine_driver) could not open control for card 0 ALSA lib
