I followed the instruction posted in this tutorial to install pulseaudio-module-xrdp. If I go to the Settings Applet and select sound, then I see xrdp-sink object under sound card. And in the microsoft mstsc.exe client, I enabled sound redirection. I tried both options for client and for remote machine. Both has same result that I don't get any sound. What I want is to play the sound on the remote machine. Is it possible to change the audio driver to headphones on the remote computer?
$ sudo aplay -l

A test sound is working for sudo:
$ sudo aplay /usr/share/sounds/alsa/Front_Center.wav
Playing WAVE '/usr/share/sounds/alsa/Front_Center.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Mono
For user the sound test fails, also after adding my user to audio group:
$ sudo adduser user-name pulse-access
The user `user-name' is already a member of `pulse-access'.
$ sudo addgroup user-name audio
[sudo] password for user-name:
Adding user `user-name' to group `audio' ...
Adding user user-name to group audio
Done.

There is an updated script and instruction blog post. Possibly you just need to run pulseaudio -k manually.
