Okay, using that hack fixes the problem (both SoC and CoP have sound now without hanging). So it's definitely a bug in wine trying to use OSS although it's not compiled into OpenAL (thus ignoring the system defaults) as any other application uses the correct default OpenAL device (except wine). This is a working work-around but can't be the solution.
it is a bug in openal-soft if you include portaudio since portaudio probe all supported devices (check whether portaudio has oss as backend)
