Hi Mateusz. Please don't install generated libpulse.so.0 system-wise. Original project proposes to installing those libraries in a separate location and using a wrapper script to launch applications for a reason. There is still vast amount of API not implemented in apulse, so it can't be a full replacement of the PulseAudio. But the fact system have libpulse.so.0 available for an dlopen() call confuses applications, they start to use PulseAudio interface even if they have code for ALSA. Google Chrome is the one example of an application which is broken by apulse installed system-wise.
Minor fixes: manual page mentions gxkb. (Was manual page created by changing gxkb's one?). -- Rinat
