Re: Baffeled with IllegalArgumentException exception

It doesnt look like a hardware issue, coz the exception is thrown
randomly. Sometimes the program works fine and plays the audio
properly. But sometimes it fails with IllegalArgumentException !. If it
is a harware problem the exception will be consistent, But in reality
it isnt!!.

Hi,
Iam using java sound API to play the audio. Iam using the Clip class to
play the audio. Frequently i get the following exception...

java.lang.IllegalArgumentException: No line matching interface Clip
supporting format ULAW 8000.0 Hz, 8 bit, mono, 1 bytes/frame, is
supported.

The exception is thrown in the code line "Targetclip = (Clip)
AudioSystem.getLine(info);"

The code snippet which throws the exception is as follows...




//Converting Audio Format
if (format.getEncoding() != AudioFormat.Encoding.PCM_SIGNED) {
System.out.println("*** Converting...");
format = new AudioFormat(
AudioFormat.Encoding.PCM_SIGNED,
format.getSampleRate(),
format.getSampleSizeInBits()*2,
format.getChannels(),
format.getFrameSize()*2,
format.getFrameRate(),
true); // big endian
stream2 = AudioSystem.getAudioInputStream(format, stream2);
}
printDebug("((int)stream2.getFrameLength()*format.getFrameSize()):
" + ((int)stream2.getFrameLength()*format.getFrameSize()));
DataLine.Info info = new DataLine.Info(Clip.class,
stream2.getFormat());
// DataLine.Info info2 = new DataLine.Info(Clip.class,
stream2.getFormat(),
((int)stream2.getFrameLength()*format.getFrameSize()));
Targetclip = (Clip) AudioSystem.getLine(info);


What could be wrong?? Why this exception is thrown? How do we solve
this??

Any links, sample code OR help in any form is highly appreciate.

Thanks in advance

My best guess is that your sound card doesn't support ULAW.

I'm not sure then what the problem is. If you want to post a simple test program that will show the problem, I'd be happy to play with it.
