[FreeNX-kNX] FreeNX and Sound

[Dimitar Paskov]

Hi
I have sound working just fine so I can help.

First and obvious thing to do is to "Enable Multimedia Support" on nxclient.
Second and not so obvious thing is to configure all the programs that you want 
to play music/sounds from to use "esound" as their output plugin. Thus 
you "tell" them to forward sound to the nxagent which forwards sound to 
nxclient (via nxesd) and voala! you have sound. Be aware that sound may come 
with a little delay but thats because it comes through the network.
For example xmms -> Preferences (Ctrl+P) -> Output plugin -> choose eSound 
Output Plugin.
I tried too to make arts play through esound plugin but I have no success, so 
better use applications settings.

Good luck :)
