[FreeNX-kNX] FreeNX and Sound

[Joseph Jamieson]

Thanks Dimitar.

So, you need nxesd working to get sound.  I didn't even know it existed
- I haven't worked with anything like esd before.  Looking at it now, it
appears nxesd didn't compile correctly on one machine and it's giving me
unresolved symbols on another one.   So, that's gotta be it.

I'm guessing that when nxesd runs, anything that can use "esound" would
be able to utilize this, and nxesd will forward the audio out to the
client.   What does it do to encode the audio?  Does it use any sort of
compression?  There's really no options in the nxclient - "on" and "off"
appear to be the options.

Thanks, you've pointed me in the right direction.

Unfortunately, that's another "click it and it will work!" help
document.  It doesn't even mention nxesd or how it works.

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 :)
