ISSUE: If you try to play a song while the soundcard is busy (and you aren't using directsound or a soundcard that supports multiple WAveOutputs at once) you get an error dialog loop. Every time you OK the dialog, MM moves to next track in queue and throws the error again.
REPRO:
1. use a soundcard that only supports one WAV output at once, and/or don't use directsound as your output device.
2. Play first track in a playlist or in any MM view with multiple tracks shown (so that now playing has multiple tracks queued up)
3. Get error dialog stating the soundcard is busy and track can't be played. (WAVOUT 2.0.2.a)
4. click OK on the error dialog
EXPECTED: After OKing this error, playback should stop and transport should go to stopped mode.
ACTUAL: Track is merely skipped, and next track tries to play, throwing error again. You can't not stop MM to stop this error loop for repeating for every track in the play queue. If you have more than 20-30 tracks in the playlists, you'll likely CTRL-ALT-DEL out.
SYSTEM: WinXP Sp2, Creative Soundblaster card. DX9, MM 2.5.5.0985 (debug)
