--- I cannot query the version string unless a device context is created. Since OpenAL-1.12 added support for thread local contexts I use that to determine whether pulseaudio should be ignored or not. OpenAL 1.10 and older will crash on pulseaudio. Since other os's don't support pulseaudio it is safe. +static void boycott_pulse(const char *devstr, const char **defstr) { The function is badly named. It doesn't "boycott" PA but doesn't uses it on older OpenAL versions.
