javax.sound.sampled.LineUnavailableException : What am I getting this exception?

问题

As the following method is called :

private void beep_player_1() {
    try {
        //clip_Player_2.close();
        clip_Player_1 = AudioSystem.getClip();
        ais = AudioSystem.getAudioInputStream(new File(Constants.Player1_Default_Tone)); // PATH FOR THE .WAV FILE
        clip_Player_1.open(ais);
        clip_Player_1.loop(0); // PLAY ONCE
    }catch(Exception exc) {
        System.out.println(exc);
     }
}

LineUnavailableException get thrown. What could be the reason for this ?

javax.sound.sampled.LineUnavailableException: line with format PCM_SIGNED 44100.0 Hz, 24 bit, stereo, 6 bytes/frame, little-endian not supported.

I don't know about the rest, but most PCs I've encountered use 8 or 16 bit 'bit depth' while that uses 24 bits. It indicates a very finely nuanced recording quality. If 8 bit is 'phone quality' and 16 bit is 'CD quality', then 24 bit would be 'master recording quality'.
