 * Note that in most of this test we may get MMSYSERR_BADDEVICEID errors
 * at about any time if the user starts another application that uses the
 * sound device. So we should not report these as test failures.
 *
 * This test can play a test tone. But this only makes sense if someone
 * is going to carefully listen to it, and would only bother everyone else.
 * So this is only done if the test is being run in interactive mode.
