I had several problems with Fieldrunners from Humble Bundle. The first problem is: There is only a 32 bit version, even though I get a download link for a 64 bit version – but both are the same.
The next problem is this error message:
cannot open audio device (Device or resource busy) Fieldrunners: pcm.c:923: snd_pcm_state: Assertion `pcm' failed.
This is because Fieldrunners uses alsasound but on my system, PulseAudio blocks the audio device. To fix that, run the game with “padsp“:
padsp /opt/fieldrunners/Fieldrunners
which gives this error
ERROR: ld.so: object 'libpulsedsp.so' from LD_PRELOAD cannot be preloaded: ignored.
This is probably because padsp can’t find a 32 bit version of “libpulsedsp.so”. For openSUSE, you can find the package here: http://software.opensuse.org/package/pulseaudio Make sure you click “Show other versions” so you can select the 32 bit version (the browser will show you the 64 bit version if you use a 64 bit version of openSUSE).
Click on “32bit” to download the file (don’t use “1 Click Install”)
Use atool to unpack the archive (trying to install it with “rpm” or “1 Click Install” will fail since the package is for the 32 bit version of openSUSE). Copy the file “…/usr/lib/libpulsedsp.so” to “/usr/lib/libpulsedsp.so”. “padsp” will find it. Now you can run the game.
Unfortunately, the audio will be choppy for some reason. I have no solution for that (it’s also choppy when you disable pulseaudio). My workaround is to go to options and to disable sound effects and the game music.
