I have never been able to get the audio part of OpenWonderland to
work. It seems to be working on the clients (Audio Test) but not on
the server. The dumb question is : does the server have to have a
working audio card in it or does the server just act as a traffic cop
for the UDP packets? I had just noticed that the audio doesn't seem
to work on the server machine (can't play a CD).
The server does not need to have a sound card. It treats the audio as streams of bytes, and doesn't ever try to use it as sounds. If the audio test is working, but in-world audio is not, that usually means there is a networking problem between the client and the server. Is the server outside a firewall, or something like that?

Jon,
Its sitting on another table in my office. Right now all of the
machines accessing it are behind the campus firewall on the same
network. The server is running Ubuntu 9.1. I don't think the udp
ports are being blocked by Ubuntu but I don't know how to tell if they
are. BTW, when I access the OpenWonderland Community server from my
office the audio works.

For future reference, the issue was that the voice bridge was listening on the wrong IP address. We diagnosed the problem using "netstat -an | grep 5060", which showed that the voice bridge was listening to "localhost" rather than the external IP address. The solution was to edit the voice bridge properties and set the value of the voicebridge.local.hostAddress to the external IP address of the machine.

Digging back into past emails I checked this on my machine wayward4now@iam:~$ netstat -an | grep 5060 tcp6 0 0 192.168.0.2:5060 :::* LISTEN udp6 0 0 192.168.0.2:5060 :::*
wayward4now@iam:~$
So, I'm good there. I just cannot configure nor test the audio system via client tools. I checked alsamixer and pulse. Everything is looking good, I have plenty of audio on my system. Strange this. Ric

Rick, I spent a good portion of yesterday troubleshooting audio on my Ubuntu 11.10 box. Lessons learned are: audio on Ubuntu 11.10 is a nightmare, audio w/ 64 bit Sun Java on 11.10 is also a mess, and that audio on a machine with two soundcards makes my hair fall out faster than it already does,
My solution was to use a USB headset, alsamixer to set the volume, and pavucontrol to disable all other sound cards and set the USB headset as default. I now have sound in Wonderland on Ubuntu 11.10.
My understanding is that many of these issues are going to be ironed out in 12.04. Looking forward to that release.

I never had to disable a sound source, I would do the sound test with pavucontrol open and when the record line twitched, I would set that input to my USB headset mike. And then everything just worked.
BUT!!! I think I know what it is!! I had this happen long ago and just remembered. When you install Ubuntu it loads up OpenJDK. The devs have a script that sets up alsa audio just for java. If you erase the openjdk packages, you lose that bunch of scripts. Actually there is no reason to erase openJDK, if you want to install the Gospel Java from Oracle.
Well, I DID delete the openjdk packages. I bet THAT is my problem. So, my 12.04 DVD is on the way, in the mail. I'll re-install fresh, right down to formatting my drive, and I betcha when I leave openjdk alone this time, I can install Oracle Java and still have those alsa config files for java intact. I went through this several years ago. And I didn't remember until now. Dang me, Ric
