Having just set up the MRA I've noticed that if I trigger (via bellpress) a doorbell action it operates but there is a noticeable 'bleed through' from the source before the wav file is played. For example the sound for the Tuner1 is off (volume off), the bell trigger is sent then I hear a brief amount of music from Tuner1 before the doorbell is sounded. If I select the source to be something where no sound is transmitted then obviously all is good - just plain ol' doorbell sound. Is this 'bleed through' normal behavior ? It doesn't seem right to have to code some logic to swap to a sound free channel when the volume is turned off ...
