Java sound problem on Gazelle

[sandygmaharaj]

When I try to run SIP communicator (www.sip-communicator.org), I get the following error:


sip-communicator -v

Interesting line here is;
javax.sound.sampled.LineUnavailableException: line with format PCM_SIGNED 44100.0 Hz, 16 bit, stereo, 4 bytes/frame, little-endian not supported.

This program works fine on a Compaq system with ubuntu. What could be wrong?

645 Plugin Component type is not supported.Should provide a plugin in AWT, SWT or Swing

That's the important line. Either there is something about your sound card not supported by Java, or your JVM is having difficulty dealing with the program.

My gut feeling is that you are using java-6-openjdk to provide java on your system. Open JDK isn't quite ready for the big leagues yet. Try this...



sudo apt-get install sun-java6-jdk #Install Sun's Java

sudo update-alternatives --config java #Select the number that corresponds to Sun's Java.

sudo reboot

Now retry your program.
