This is embarrassing, on account of there being a respectable chance that I once berated someone for not being able to figure out this same problem, but I can't seem to get music to play in any version of Zelda Classic that I download, between 2.10 and 2.5 alpha. The sound effects all work exactly as they're supposed to; it's just the MIDI music that it can't seem to handle.
Sound/Music Question
What system and build?
Right, yeah, that... It's Windows. Both 2.10 and the latest build of 2.5 (either 901 or 910. I'm feeling a little dyslexic at the moment).
Go to Start->Control Panel->Sounds->Device Volume and click "advanced". Make sure your Synth volume is turned up. (You can also simply double-click the volume icon in the taskbar to get to this). That should fix the problem.
You, sir, are a beautiful, beautiful man, or other applicable [noun].
Thanks.
