Given that the extension block is how host software knows that the monitor 
supports sound, that's completely unsurprising.

If I had to guess, the host software (by which I mean, nvidia's driver) is 
being aggressive at changing the InfoFrame that tells the monitor how many 
audio channels there are, and the monitor treats that as a full mode change and 
not just an audio config change.  But that's shooting in the dark.
