I have the ltsp "almost completely working" at this point except for sound on the workstation. The server is working fine, including OSS sound and I don't want to break that. I am not using "local apps" on the workstation. Although I may choose to do this at some point, I am hoping that it is not necessary to get sound working. I need to use OSS sound from the workstation in order for certain applications to function properly. I am using the "cmpci" sound module.
I am using the "aRts Driver (libartsout.so) for the server XMMS output plugin. I also have a number of entries in my server "mocules.conf" file that relate to sound, including an "OSS/Free" portion. I have no problems with sound on the server. I can play wav files from the workstation by running "esdplay" but otherwise no sound comes from the workstation's speakers. If the same user is logged into the server and workstation, I get sound from the server's speakers that is generated from the workstation If different users are logged into the workstation and server, I just get an error about the "dsp" upon booting the workstation. I can not get any sound generated from the workstation. Does anyone know how to accomplish this (OSS workstation sound without causing any server problems)?

When you boot your diskless workstation, if you watch carefully, you should see the kernel modules for your sound card loading, followed by a message saying something like 'accepting audio input on port 16001'. Back on the server, let's say you have xmms installed, and some .mp3s waiting to test. Within xmms, choose 'options' -> 'preferences' -> 'audio I/O plugins'. Under 'Output Plugin', select the 'eSound Output Plugin'. If you now click 'configure', under 'Server' you should see 'use remote host' selected, with a hostname of 'ws001.mydomain.whatever' with a port of 16001. So, what is happening on the host is that when the user plays an .mp3 though xmms, the output goes to the eSound plugin, which fires it off over the network to port 16001 on your the diskless workstation 'ws001.mydomain.whatever', where it is played. So, through the miracles of networking, twenty different people can all run xmms on the server and still get the sound coming out of the local workstation they are using. You should also note there is no security on this, so a malicious user could redirect their music through someone else's workstation...
