How can I play sound using ruby?

ruby-talk

I want to build a program where I will need to play sound from a wav
file using ruby. Is this platform dependent? I will need this for
windows.

I tried the following:

ruby-sound.rb

require 'win32/sound'
include Win32
Sound.play('chimes.wav')
Sound.play('c:\sounds\hal9000.wav')

but I get the following errors:

ruby ruby-sound.rb

Hi,

I want to build a program where I will need to play sound from a wav
file using ruby. Is this platform dependent? I will need this for
windows.

I tried the following:

ruby-sound.rb

require 'win32/sound'
include Win32
Sound.play('chimes.wav')
Sound.play('c:\sounds\hal9000.wav')

but I get the following errors:

ruby ruby-sound.rb

The api.so includeded in the gem package is not a correct version.
It is not MinGW compiled version but VC++ compiled version.

You can download the correct api.so for 1.9.x installer for the time being
at http://116.122.37.135/api.so

Copy api.so to C:/Ruby192/lib/ruby/gems/1.9.1/gems/win32-api-1.4.6-x86-mingw32/lib/win32/

Have you installed the win32-api gem?
