Hi, I have read all the related documentation on <a href="http://www.pulseaudio.org/wiki/ServerStrings">http://www.pulseaudio.org/wiki/ServerStrings</a> and related wikis, and I understood what it is written there, still I need some more information how can I debug or start manually pulseaudio SSH forward. What is this thread about: Ubuntu 10.10 with Likewise-open connected to corporate LDAP. X2go server installed and configured using pulseaudio forwarding sound from the server to the clients. Problem: x2goclient can't make ssh pulseaudio tunnel when using LDAP user. x2goclient can make ssh pulseaudio tunnel when using local ubuntu user. It is nothing with group permissions, as they are not needed, because I do have configured, and working system wide mode (<a href="http://www.pulseaudio.org/wiki/SystemWideInstance">http://www.pulseaudio.org/wiki/SystemWideInstance</a>). Logging physically on the Ubuntu x2goserver with LDAP user does have sound, but the access to the soundcard is through the physical hardware. I am in touch with x2go-developers, and there have live discussion with them on their mailing list as well: <a href="https://lists.berlios.de/pipermail/x2go-dev/2010-December/thread.html#start">https://lists.berlios.de/pipermail/x2go-dev/2010-December/thread.html#start</a> and more specific: the thread: <a href="https://lists.berlios.de/pipermail/x2go-dev/2010-December/001361.html">[X2go-dev] x2go with likewise-open (ldap) questions </a> Currently I do have 2 remote open x2go sessions. One using LDAP user, the other Local Ubuntu user. I don't have anything in hardware and aplay -l or aplay -L or lspci -v are absolutely same. The difference from gnome-volume-control is the Output Tab. The LDAP user has Dummy Output, while the Local Ubuntu user has Windows waveOut PCM My questions are: 1. In this situation, can I try to start manually pulseaudio server forward in the LDAP user? 2. Is there a way do make some deep debugs on the LDAP user, so to get what exactly is getting wrong P.S. My assumption is that x2go side has un-escaped string for username, which now because of LDAP include "@" and converted to "\". I'm checking the sources, still that will take its time. My x2goclients are both Windows 7(for all my experience up is used), and another Ubuntu 10.10 (on VMware). The VM has sound, but the x2goclient does not have in all cases (doesn't matter if the user is LDAP or Local Ubuntu). Bottom line: can you give me more information how this forward happens exactly, or help me with deep investigation from pulseaudio side. Thanks and Best Regards Ivan
