   1 /*
   2  * Tests basic sound playback in DirectSound.
   3  * In particular we test each standard Windows sound format to make sure
   4  * we handle the sound card/driver quirks correctly.
   5  *
   6  * Part of this test involves playing test tones. But this only makes
   7  * sense if someone is going to carefully listen to it, and would only
   8  * bother everyone else.
   9  * So this is only done if the test is being run in interactive mode.
