I'm surprised unless it's a small amount of bleedthrough. Setting both 
channels of control.3 to 0 should silence it. This should silence the 
speaker entirely:

         control.94 {
                 comment.access 'read write'
                 comment.type BOOLEAN
                 comment.count 1
                 iface MIXER
                 name 'Amp Spk Switch'
                 value false
         }

See:
	http://wiki.openmoko.org/wiki/Linphone
This points to http://www.koolu.org/voip-handset.state which I have used 
successfully with the CLI version of linphone compiled using 
mokomakefile a while back. FDOM currently has a more recent linphone 
with GUI and presumably a working voip-handset.state too.
