The only problem I had was that it was still using the old config.xml file located in ~/.wormux/, which was pointing to an older wormux installation. After fixing the path everything was working nicely.
Ah - I deleted the old config file. Now sound is working, but only when set to 22kHz. Unfortunately I cannot set it back to 22kHz once it's set the 44kHz without crashing. Fullscreen still not working :-(
