Can't monitor record enabled tracks...intermittent

[gollywillickers]

this problem has really been annoying me lately.


i'll be monitoring record enabled tracks just fine.
i record. everything's fine.
then all of a sudden
i record enable some other track
and i cant hear any audio.

wtf?

the level indicator shows i am getting input.

everything is as it shuold be
but no sound.

the only thing that seems to bring it back is
save > quit PTLE > open session again
and then all is fine.

it seemed like it used to only happen with
the audio coming in from midi track's audio devices -
even though that should not have anything to do with it.

but now its everything vox, guitar, keys.

really frustrating at times.

running 6.9.2
and its happening a lot lately
