I've tried to backport libswf and swdec-gnome to my system (libswfdec-0.6-90_0.6.6-1~8.04prevu1_amd64.deb swfdec-gnome_2.22.2-1~8.04prevu1_amd64.deb), however it still doesn't produce any sound. If i run swfdec-player in terminal I get
ALSA lib pcm_dmix.c:874:(snd_pcm_dmix_open) unable to open slave
Failed to open sound device: Device or resource busy
so it's probably problem caused by using ALSA directly while a sound card doesn't support hardware multiplexing.
