Tried 0.9.4 on Mac OS X 10.7.3, sound is not as crappy as 0.9.2, but it only works for about 10 seconds, then complete silence. Sound won't work even after I hit F12, insert another floppy and select reset, no sound at all, even the nice floppy sound, it's completely silent. I quit out, then restart, and again the same thing, I can only play Giana Sisters for about 10 seconds before it goes silent.
Just tired leaving it on the Kickstart screen for several minutes, and floppy clicking sound continues, so it's a problem while playing the game that kills the sound.
Also tried leaving music playing at the start of Hybris for several minutes, no problem at all.
Gave you a plug on the following website too;

Keep up the great work.
