when i run lbreakout2 errors come up in the terminal saying

/dev/dsp.Device or resource busy

audio_open: cannot open device:No available audio device

sound.chunk_load:cannot load WAV 'various different files' as audio device isnt initiated properly.

and i get no sound in the game. i can hear mp3's fine and startup sounds work well.

ive tried uninstalling and reinstalling, all necessary SDL libraries are installed and no errors are given but still cannot hear the game. any ideas?

If you are using KDE then try starting lbreakout from a konsole with

artsdsp lbreakout

nope, im using xfce

I had the same problem. I found a clue looking at the strace (or truss) output of lbreakout:

strace lbreakout2

I found the following lines:
stat64("/dev/sound", 0xbffff26c) = -1 ENOENT (No such file or directory)
open("/dev/dsp", O_WRONLY|O_NONBLOCK) = -1 EBUSY (Device or resource busy)
stat64("/dev/dsp1", {st_mode=S_IFCHR|0660, st_rdev=makedev(14, 19), ...}) = 0
open("/dev/dsp1", O_WRONLY|O_NONBLOCK) = -1 ENOSYS (Function not implemented)

So /dev/dsp was busy. It appeared I had a sound daemon running (esd). When I killed that one, lbreakout made its very usefull sounds again.

I hope that this helps for your situation.

Ruud.
