Autodisable Audio

Postby shevegen » Thu Jul 09, 2009 2:02 pm

lib/ruby/site_ruby/1.8/rubygame/named_resource.rb:105:in `autoload': Could not load Sound file './whiff.wav': No available audio device (Rubygame::SDLError)
lib/ruby/site_ruby/1.8/rubygame/named_resource.rb:105:in `[]'
from chimp.rb:237:in `main'

My sound is broken right now. Is it possible to autodisable audio in case the sound is broken or can not be found? I'd like to just run the samples and dont mind if audio output is not possible

Edit: Nevermind, I just set the two variables to false and now it works. :)

I still wonder how to check for audio output possible?

Per gamebox's sound_manager.rb:
puts 'Warning, sound disabled' unless
(@enabled = (Rubygame::VERSIONS[:sdl_mixer] != nil))

I think that's what you're looking for. Note, that if your rubygame was compiled with a valid sdl_mixer, then it got broken, I don't this approach will work.

You could also try this to detect the problem ahead of time:

Code: Select all
sound_works = begin
              rescue Rubygame::SDLError => s
                warn "Audio failed: #{s.message}"

Rubygame.open_audio is not normally needed, since it will do that automatically when you play a sound or music, but it's useful in this case.
