tcpwrappers & shell execution

How can I play a .wav file as part of tcpwrappers?

For instance: '/usr/bin/wavp siren.wav' plays the file just fine.

However, placing the below line in /etc/hosts.deny does not work:

ALL: ALL: (/usr/bin/wavp siren.wav)&

In fact, the output of 'tcpdchk' reports the following:
error: /etc/hosts.deny, line 1: bad option name: "(/usr/bin/wavp"

Any help?
