You don't need to delete your asound.state. Just edit it with your favourite 
editor and check where the settings of EFX Voices Mask are. You can find them 
easily as this has ca. 32 lines with true or false (mostly false before your 
editing). Change all these into true and voila!

One thing to remember: While editing this file, alsa shouldn't be loaded...

/etc/init.d/alsasound stop
vim /etc/asound.state
/etc/init.d/alsasound start

Perhaps this helps...

There is a theory which states that if ever anyone discovers exactly what the 
Universe is for and why it is here, it will instantly disappear and be 
replaced by something even more bizarre and inexplicable.

There is another theory which states that this has already happened.
