Unable to initialize audio hardware

[DrewCCU]

whenever i try to run a AGS game i get a pop up that says:

Unable to initialize your audio hardware.
[Problem: Failed to init MIDI music driver]

the game runs but theres no sound/music.

i'm running windows vista but i don't usually have problems with the midi driver.  And no, there's not any other programs that would be using the midi driver running while i run the game - so i know the driver is not in use when i run the game.  I don't know - I'm kind of stumped.  Any ideas?

Error: "Unable to initialize your audio hardware (problem: Failed to init digital sound driver)"
When I test my game (which has NO sound or music yet), OR when I play someone else's game, I get an error that says, “Unable to initialize your audio hardware (problem: Failed to init digital sound driver)”. What is the problem?

Well, so far three things have helped some people:

First off, make sure Windows Media Player isn't already running in the background. This can screw things up. Close all programs that even use WMP, like some FireFox extensions do. There also might be other programs that use the digital sound driver, like Winamp, QuickTime Player, and Real Video Player. I'm not sure if these programs use the same drivers that AGS does, but it's worth closing them all just in case.

Go into your DirectX settings program (usually "dxdiag.exe", sometimes in a "386" folder). Click on the sounds tab and move the slider to "Full Acceleration". Try it now.

Also, a much quicker way is to open up the Game Setup window in AGS and change the digital sound setting from "Default Direct Sound" to "Default WaveOut Device".
