Convert a Sound to a List?

With “SampledSoundList” it is possible to create a sound based on a list:

list = Table[Sin[2 \[Pi] 500 t], {t, 0, 1, 1./2000}];
sound = Sound[SampledSoundList[list, 2000]]

Is it also possible to create a list based on the sound? I think this should be easy but I dindt found a way to do this with Mathematica 10.

Thx for your help & kind regards.
