Unless the mute block causes an EOB tag to be sent downstream to the UHD 
sink, that won't have the desired effect.

When doing half-duplex, sharing a common RF port, the USRP needs to know 
when you've ended a "burst", so that it can
  switch the antenna port between the RX and TX.  And again when you 
start transmitting, it'll need a SOB tag to cause
  the TX state machine to wake-up.

The usual mode implemented by gr-uhd is continuous streaming on TX.
