PowerPoint 2013 Changes display setup

I work at a university and we just deployed Office 2013 within our labs and instructor stations. First week and already causing major concerns with our Audio system, which is routed through HDMI with video. When the display extends to the projector on All in One units (we use splitters most locations), audio is lost. I need a way to disable for all users, at least until AV can decide if can capture the audio on a change. I've identified what maybe the registry key in hku but need something more else, preferable in hklm.

When is this "revisit" happening then?

I work in Sweden's largest conference centre in Gothenburg and this "feature" is still confusing presenters and destabilising conferences on a regular basis. Many clients in fact demand that we DO NOT have the latest version of  PowerPoint installed.

I really do not understand the logic in the thinking that you have a customer group you feel are not familiar with making basic graphic card settings so you are going to change the settings for them and leave them in a position where they must change them back by themselves, only, hold on, your starting point is that this group does not know how to change them by themselves in the first place. In fact the customer group is unaware of what has happened at all and people are enormously confused. This is sometimes exacerbated by the fact that the resolution of the presentation screen may not have been set up for extended desktop mode so that not only is one left in a screen configuration one has not chosen, but also with a picture which suddenly no longer fits the screen properly.

There is of course the ability to choose to run in duplicate mode from the top of the screen when you have started your PowerPoint but even choosing this still alters the screen configuration to extended desktop mode on exit. Why?

Also whereas 2013 is the first PC version to do this the Mac version of PowerPoint has long had default presenter view, but on all the Macs I have tried this on it DOES reinstate the original configuration on exit from PowerPoint. Please explaint to me why not for Windows users.

Tweaking the registry is of course an advanced solution with inherent dangers if not performed properly. Given the fact that you do not trust this customer group to even be able to press WINDOWS P once to choose extended desktop mode, do you really think that letting them loose in the registry is or good idea or something they will be able to understand or even dare to attempt?

Please sort this out .. at least make it an option rather than a standard setting .. it ruined a conference today and it is quite frankly a thorn in the side.

Oh, and please link me to the forum where you reply about video (in)compatibility within PowerPoint as well thanks.

Cheers

Gosh, Richard, it's only been two years. Give 'em time. (I hope you can hear the sarcasm.)

Sure wish we had a "like" button on this forum so I could like your post. (And that's not sarcasm.) Guess I'll settle for "helpful."

Better a couple of seconds to switch topology than immediately dumping me into a view that is confusing, doesn't fit, and is not what I want or what I was using prior to Presenter View. (When I'm demo'ing, it's a nightmare.) C'mon, Microsoft -- this is getting old. 

I wonder what PowerPoint 2016 does?

So, the RegEdit works great for ending a presentation and going back to Duplicate mode. However, I go from presentation to live demo within the slide show. I don't end it, just do a demo...because I'm coming right back to the presentation. I really like my new Dell work bought for me but I'll be going back to my old Mac because Office 2010 just works on that machine.

I am not surprised at this move by Microsoft. All you have to do is look at the debacle of Win8 (and Vista, and ME, etc) and you can see the pattern. Totally screw up one release, the fix it five years later, in the next release.
