Preview Build Freezes On Slides With Audio

Aug 12, 2011

Hi Group

I have a brand new Windows 7 Pro notebook that generally handles Articulate 9.2 pretty well.

A major problem, however, is that pages with WAV audio imported freezes during 1) preview, or 2) during audio import.

This was deduced after a bunch of trial and error, and watching the Articulate debug window.

It appears that whenever Articulate goes to determine page length when audio is involved will cause it (Ap6.exe) to go to 0% CPU usage and just sit there.This manifests as a 'freeze' in PPT/Articulate. Killing that process usually allows me to access PPT again.

Situations where a freeze will occur:

E.g.1 when doing an audio import the log stops at:

AP6:ProcessAudio:Check length of C:\Users\xxx\AppData\Roaming\ARTICU~1\PRESEN~1\Project\971D99~1\NARRAT~1\track256.mp3

AP6:GetWavLengthInSec:Using audio copy... [hangs here]

Note that the mp3 file specified in the above log entry does exist and can be played OK.

E.g.2 when doing a preview on a page with audio the log stops at:

artspconv:TraceOpen:Timing:GetTotalTiming

artspconv:TraceOpen:GetTotalTiming:TIMELINEEDIT:

artspconv:TraceOpen:GetTotalTiming:TIMELINE: [hangs here]

I am able to play the WAV files OK on the machine using media player, so don't think it's a codec type issue.

As far as I can tell I have rights to the areas that I should have them.

Other machines are able to process the Articulate files OK, so it seems to be something local to my PC. 

Why would this be happening on this machine, do you think?

Thanks for any advice on this.

Hi Pete,

I believe that your issue has to do with the audio codecs on your machine.  Please install the codec pack shown below:

K-Lite Codec Pack Full (accept all default installation options): 
http://www.free-codecs.com/K_Lite_Codec_Pack_download.htm 

After that, restart your computer.  

Then, launch PowerPoint, select the Articulate menu & choose the Audio Editor.  Select all of the audio (Ctrl + A) and increase the volume by 1%.  Click the Save & Close button to save the changes.

Finally, publish your presentation. 

If you continue to have issues, please let me know.

Package + software versions uploaded as requested.

I fully expect the package to preview/publish OK for you. It seems to be a local PC issue, but I don't understand what could be the problem on a clean Windows 7 install.

Hopefully the debug log snippets in my earlier post will give a really good indication of what the Presenter software is doing, and limit the possible problems. Permissions to a particular folder, for example.

Note that I've tried with MP3 as well as WAV, so the actual media wouldn't appear to be at fault.

I look forward to hearing the possibilities.

Thanks.

Hey Pete,

Have you tried reinstalling the Articulate Studio with the Windows 7 UAC (User Account Control) slider pulled all the way to the bottom (disabled)? This would require you to restart before reinstalling but can help resolve strange and system specific behavior as you have described.

More on disabling the UAC is noted in the following link.

Hi Dave et al.

Just to let you know that we found an identically spec'd machine; same BIOS, OS, service packs, model, application software - was even delivered to us on the same day from the same supplier as the problem machine - to use as a control.

Articulate works perfectly on it.

Obviously there is something deep in the machines that is different but I've spent enough time looking and it's easier to just switch to this second machine that works.

It's a cop-out, I know, and I'd like to have gotten to the bottom of what was going on, but it's not practical at the moment.
