7511 input clock change disturbs monitor audio

When the clock input to my 7511 changes, I find that some monitor's audio does not recover gracefully; it becomes aliased and noisy.  The clock changes due to upstream format changes, for example 1080i_50 to 1080i_59 will change the clock from 74.25 to 74.25/1.001, and the clock might even go away for a period of time. Of course, this also creates a disturbance in the TMDS clock that the monitor apparently is sensitive to.  I believe that I have determined that my 7511 is recovering fine; it is the monitor that is confused.  But I still need to help the monitor recover audio.  Is there a way that I can do something within the 7511 that will cause these monitors to resynchronize audio?  I am OK with letting the monitor start over again as though it were hotplugged, but there doesn't seem to be a way to do this by software control.
