Now that Ubuntu 8.04 is out and all the old info is archived, I figured it was time for a new thread on OSS4.
Link to the OpenSound System project forum: http://www.4front-tech.com/forum/index.php
I encourage you to register an account there and use their Linux forum if your issue is more pertinent to OSS itself and not installing/using it on Ubuntu. This ensures that users of other Linux distros will have a chance to benefit from or give feedback on your issue, and ensures that we keep non-Ubuntu issues off of these forums, which are already loaded with unresolved issues.
I will be updating this thread with new information and announcements, so remember to subscribe to it.
