I'll do some googling to see what has changed for SourceDataLine usage.  I've been out of Java programming for a while, so will take a little catching up.

Some output about the system might also be helpful.  Could you run the following (with Java 10 on the system that has the problem) to get information about available mixers and supported formats?

Code: [Select]
        Mixer.Info[] mi = AudioSystem.getMixerInfo();
        for (Mixer.Info info : mi) {
            System.out.println("info: " + info);
            Mixer m = AudioSystem.getMixer(info);
            System.out.println("mixer " + m);
            Line.Info[] sl = m.getSourceLineInfo();
            for (Line.Info info2 : sl) {
                System.out.println("    info: " + info2);
                Line line = AudioSystem.getLine(info2);
                if (line instanceof SourceDataLine) {
                    SourceDataLine source = (SourceDataLine) line;

                    DataLine.Info i = (DataLine.Info) source.getLineInfo();
                    for (AudioFormat format : i.getFormats()) {
                        System.out.println("    format: " + format);
                    }
                }
            }
        }

I'm not at my computer to do any tests now, so if the above code is outdated and doesn't work, no problem.  I'll see if I can recreate the problem on my computer when I get home later.

So I've been doing some digging and debugging, trying to figure out what's the issue is between java versions and I've got something that seems worth mentioning. It seems using Java 8 when retrieving the SDL (which is where the error occurs in Java 9+), a DirectAudioDevice is used to run getLine(Info). While in contrast in Java 9+ a PortMixer is used to run getLine(Info). Not quite sure why it chooses a different device. I'm really hoping you'll help me here Paul, you've got a lot more knowledge of the structure of this program and what exactly is going on here. Thanks again!

EDIT: I think this is due to the ranking system. It seems this method of finding the correct mixer might be dated. Going to try and enable debug messages (forgot which class you just ended the try catch with a semicolon) and keep digging.
