Summary: AIF files fail normalisation or playback

Initial Comment:
Xena v5.0.0 Stable Branch. Audio plugin v0.5.5 b10. 

Xena viewer can't playback normalised AIF audio files. Other AIF files fail normalisation. Tested in Linux only.

To reproduce: 
1. Normalise AIF file. 
2. Use Xena Viewer to open AIF file.
3. Click play.
Result: No error is displayed in the GUI - I just can't hear anything being played. The following error is displayed in the console:

java.lang.IllegalArgumentException: unable to convert FLAC 96000.0 Hz, 24 bit, stereo, unknown frame size, unknown frame rate,  to PCM_SIGNED 96000.0 Hz, 16 bit, stereo, 4 bytes/frame, little-endian
	at org.kc7bfi.jflac.sound.spi.FlacFormatConversionProvider.getAudioInputStream(FlacFormatConversionProvider.java:298)
	at au.gov.naa.digipres.xena.plugin.audio.AudioPlayerView.initAudioLine(AudioPlayerView.java:130)
	at au.gov.naa.digipres.xena.plugin.audio.AudioPlayerView.access$400(AudioPlayerView.java:50)
	at au.gov.naa.digipres.xena.plugin.audio.AudioPlayerView$1.actionPerformed(AudioPlayerView.java:95)

I have reproduced the above with a couple of different AIF files. File command gives: outputfile.aif: IFF data, AIFF audio or alaw.aifc: IFF data, AIFF-C compressed audio. I can supply a variety of samples. I have also checked that the version of flac I'm running is 1.2.1.
 
Some AIF files fail normalisation with the following error displayed in the GUI and console:

java.io.IOException: An error occured in the flac normaliser. Please ensure you are using Flac version 1.2.1 or later.NOTE: --keep-foreign-metadata is a new feature; make sure to test the output file before deleting the original.

Message:
Errors from failed normalisation vary, depending on the type of AIFF file.
