No sound - game crashes when turning on sound

What i expected to happen was:
i click on the scrollbar at "sound" and put it at my desired number.

What actually happened:
i click on the "sound" button, Minecraft window closes and a error file appears at my desktop

Steps to reproduce:
1. start minecraft
2. go to "options"
3. click on the button labeled "sound"
4. notice that minecraft crashes
i have attached the error files below.
Deleting the bin file and reopening minecraft doesn't work either.
