Hi, yes, I get the following output from jshell:

    % JAVA_VERSION=22 jshell
    |  Welcome to JShell -- Version 22.0.2
    |  For an introduction type: /help intro

    jshell> javax.sound.sampled.AudioSystem.getMixerInfo();
    $1 ==> Mixer$Info[1] { oss [default], version  }

And the test program ran and played the test file just fine:

    % JAVA_VERSION=22 java ./audio-test.java pure-tone.wav
    The following mixer available:
    oss [default], version
    pure-tone.wav: input format: PCM_SIGNED 44100.0 Hz, 16 bit, mono, 2
bytes/frame, little-endian
    pure-tone.wav: using format: PCM_SIGNED 44100.0 Hz, 16 bit, mono, 2
bytes/frame, little-endian

`audio-test.java` is the file you attached to this issue.

If you install alsa-utils, what is the output of `aplay -L`? And is aplay able
to play any audio files?
