both the clock and the audio circuitry would be *inside* this chassis, 
therefore the chassis has nothing to do with shielding one from the other. 
The degree to which digital switching noise gets into audio generally has 
to do with the PCB layout, the parts selected, and to some extent the 
circuit design itself.

the purpose of a chassis electrically is generally to keep electrical 
noise 
generated inside the box from getting outside in the form of EMI, and to 
keep outside EMI from getting in and interfering with the circuits inside.
