[X2Go-User] no local sound with x2go

[looper at gmx.li]

I use X2Go with Debian Linux Wheezy (server version: 4.1.0.0-0x2go1.1~git20160225.1310+wheezy.heuler.1, client version: 4.0.5.2-0x2go1~git20160504.1196+wheezy.heuler.1). All packages from X2go repository (http://packages.x2go.org/debian). It works fine, but I can't hear the sound local, it comes everytime on remote machine (on the x2go server). All settings are default, no changes. Is there anything I forgot do to?

I tried this with Debian to Debian machines and with windows (7, x64)  client to Debian server, same result. Thanks a lot for your help!
