Precision Monolithics, Inc. (PMI) makes some CMOS analog switches that are
specifically designed for audio applications.  They feature low distortion
and are noiseless when switched.  Part number is SSM-something.  Siliconix
also makes a large selection of analog switches, many of which are useful
for audio, but you will have to a bit more work in choosing and designing
them in.
