I am impressed by the features of Openfire and Spark, but I have one major issue. SIP plugin users have poor audio quality and they get looping sound problems during the first call. The sound loops don't go away until Spark is closed.
I have reproduced this error on a few computers with version 2.6.3. I decided to install version 2.5.8 to see if that would help, and it fixed the problem.
Is there a simple fix for this? I was reading this thread which seemed to describe the same issue: http://community.igniterealtime.org/thread/45213?tstart=30
How would someone go about changing the audio locator to dsound instead of javasound? If it requires source code editing and compiling, I'll give it a shot, but I have never programmed with Java.
