Unknown sample rate/Line Unavailable - Java

Question

I am working on a Java based Application that requires to record sound from Mic. Following is my code:

audioFormat = new AudioFormat(8000, 16, 1, true, false);
        targetInfo = new DataLine.Info(TargetDataLine.class, audioFormat);

        try {
            targetDataLine = (TargetDataLine) AudioSystem.getLine(targetInfo);
            targetDataLine.open(audioFormat, 320);
            targetDataLine.start();

        } catch (LineUnavailableException ex) {
            java.util.logging.Logger.getLogger(SoundManager.class.getName()).log(Level.SEVERE, null, ex);
        }

Here I am getting exception on line "targetDataLine.open(audioFormat, 320);"

javax.sound.sampled.LineUnavailableException: line with format PCM_SIGNED 8000.0 Hz, 16 bit, mono, 2 bytes/frame, little-endian not supported.

I have changed my PC's hardware and OS to CentOS7, the same code worked perfectly on previous hardware and OS CentOS 6.7.

I have checked the formats that my current PC Supports, which are as follows:

> 
> interface SourceDataLine supporting 48 audio formats, and buffers of

I will be grateful if I get some sort of help in this regards.
