IllegalArgumentException: No line matching interface Clip supporting...

I logged this exception:

1   2

java.lang.IllegalArgumentException: No line matching interface Clip supporting format PCM_SIGNED 22000.0 Hz, 16 bit, mono, 2 bytes/frame, little-endian, and buffers of 4610 to 4610 bytes is supported

that was on:  Linux 2.6.32-22-generic   java 1.6.0_18
Could it be that no sound card was available?
Do you think it is worth checking which formats are available? (and how do you do it?)

Do you think it is worth checking which formats are available? (and how do you do it?)

The interwebs say: http://www.jsresources.org/faq_audio.html#supported_formats

1   2   3   4   5   6   7   8   9   10

Line.Info[] infos = AudioSystem.getSourceLineInfo(); Line.Info[] infos = AudioSystem.getTargetLineInfo(); for (int i = 0; i < infos.length; i++) {   if (infos[i] instanceof DataLine.Info)   {     DataLine.Info dataLineInfo = (DataLine.Info) infos[i];     AudioFormat[] supportedFormats = dataLineInfo.getFormats();   } }

I decided to just not care and disable sound if that exception occurs.

Here I realized that 22050 is more common than 22000, I changed the frequency and hope it'll help.
