Fixed the problem of not being able to work from Haiku. The main problem was that although the multi_audio API on BeOS hands the driver the settings as made in the Media prefs, the Haiku one just gives maximum values and assumes the driver will scale the values down. I didn't do that.

If you run Haiku on HDA hardware, you should have sound now too! :)
