I am also getting "Got invalid sound number" using the lastest linux binary release. Sound and music will work for a few minutes until I move into an area where I think the music track would switch to a new one.
I am using Slackware 10.1 with Dropline Gnome 2.10 as my desktop. I am also using ALSA 1.0.9b drivers for my Soundblaster Live sound card. I just noticed that the esd sound daemon is running when I ssh'ed into my workstation. I will try killing esd and running the game to see if that solves the sound issue. If it still occurs I'll try bypassing the desktop and running it directly thru my xinitrc.
Will compiling the CVS version give out more verbose error messages so we narrow down the cause of this?
And thanks to all the developers for creating this addictive game
