automation problem is back

hi everyone, last week I asked the same question. i'm trying to use automation (volume). when I turn on WRITE then move the slider to do what I want it "prints" which means I see the envelope, however, on playback nothing changes.
the last time I asked this one suggestion was to toggle READ off and on then it worked. i'm on another project trying to do the same thing.
Bristol Jonesey asked if the control moves after I write the automation? it does not move. then he (you) said something about a routing problem. I haven't a clue what that means.
like I said before this is the first no, second time I ever had this problem.
I would appreciate any thoughts on this.
thanks

You nailed it Jonesey ( Place "Thumbs up" icon here)

For a while now I've seen projects with working volume automation have the volume automation just stop working.  The automation curve is there, but the mixer stops moving. Early on in the project it was working then something happens and it never moves.  I've not been able to work out exactly what causes SONAR to get into this mode, but once it happens saving the project and exiting and restarting SONAR and reloading it every time has fixed it.  With no additional changes.
 
Forum searches show this "disconnected" automation problem has existed for a long time.
See this post here from 2010:

The last few releases this has happened more often to me.  But it seems nearly random and can't be reproduced.  It's maddening but without a clear repeatable recipe I doubt anything can be done about it.
 
In my recent cases I'm never recording the volume automation, it's always hand-placed/edited control points.  But I'm sure the problem is possible both with recorded automation and specific nodes.

Yeah, it you simply click the W it will turn solid red. This is because you have armed every single automatable parameter - a half red W indicates at least one parameter is not armed.
