Hi Sean, thank you very much for the reply. I figured out my mistake. I actually modified the HOME environment variable in my program by using the pointer that was returned by the getenv() function. (which is not a pointer to a copy of the string but to the actual env var...) I wonder why pulseaudio is using these authentication cookies when trying to connect to a local pulseaudio server though.
