We already have this logic for Linux. Gosh! Very good work!!!

The pulsecore/core-utils.c contains a function name pa_make_secure_dir which will create a directory for the pulse cookies, but it (AFAICT) assumes that the parent dir (.config) already exists. It also may be that we don't set XDG variables not appropriately [1]. The pulseaudio patch you mention earlier [2] alludes that, too. [1] http://standards.freedesktop.org/basedir-spec/basedir-spec-latest.html [2] http://cgit.freedesktop.org/pulseaudio/pulseaudio/commit/?id=7fad67c46188991c04a42b190349ebb3f4a1756f I guess assuring that the .config/pulse dir exists is a simple approach and we should go that instead of playing with XDG env vars (which are part of the freedesktop specs and X2Go Client is not about being compliant with freedesktop specs if run on Windows).
