1123 * To summarize the following is most likely the correct behavior:
1124 * stereo not set -> prefer no-stereo formats, else also accept stereo formats
1125 * stereo set -> prefer stereo formats, else also accept no-stereo formats
1126 * stereo don't care -> it doesn't matter whether we get stereo or not
1128 * In Wine we will treat no-stereo the same way as don't care because it makes
