Version: 4.1.0.1

PulseAudio Sound fails to work when the following conditions are met:

1. The client is running RHEL 6/CentOS 6/etc

2. The client has both ~/.pulse-cookie ~/.config/pulse/cookie . For example, when the home directory is an NFS export mounted by both EL6 and EL7 systems.

Running commands like `pactl list` on the X2Go server yields "Connection failure: Access denied". 

This is because the X2Go client system is using ~/.pulse-cookie with its PulseAudio server, but X2Go Client copied over ~/.config/pulse/cookie and is having the X2Go server system use it with its PulseAudio client libraries.

This can be worked around by symlinking .pulse-cookie to .config/pulse/cookie .
