/*
 * Tests basic sound playback in DirectSound.
 * In particular we test each standard Windows sound format to make sure
 * we handle the sound card/driver quirks correctly.
 *
 * Part of this test involves playing test tones. 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.
