Im sure there are many ways but you can use the foreign function 
interface to scheme to talk to any C libary that handles sound. Two ways 
I know of to achieve this are the esd.ss file in collects/ffi/examples 
which is an interface to the ESD sound system available in most unix's. 
Another library is my allegro.plt planet package. It is a high level 
library that deals with graphics, input, and sound but you can use it 
just for sound if you wish.
