If 48kHz is not supported, automatically select lower sample rate

See this ​post:

user getting this error:

ERROR Line matching interface TargetDataLine supporting format PCM_SIGNED, 48000.0 Hz, 16 bit, mono, little-endian not supported.

It may be that his hardware does not support 48kHz sampling rate

something link this in the run method of the Capture class?:

       	// !!!!!!
          	// try to find highest supported sampling rate
            if (!AudioSystem.isLineSupported(info)) {
                int samplingRate = 44100;
                AudioFormat format = new AudioFormat(samplingRate, samplingRateFormat, numberChannels, true, false);
                info = new DataLine.Info(TargetDataLine.class,format);
                if (!AudioSystem.isLineSupported(info)) {
                    samplingRate = 32000;
                    format = new AudioFormat(samplingRate, samplingRateFormat, numberChannels, true, false);
                    info = new DataLine.Info(TargetDataLine.class,format);
                    if (!AudioSystem.isLineSupported(info)) {
