You can't, PCM is the baseline which isn't negotiated.  You can only
disconnect the sound channel.

Of course you can warn if no codec could be negotiated and offer the
option to disable sound.  Not sure it is worth the trouble though, as
far I know there is no data traveling the wire if the guest doesn't play
audio.
