Capturing StreamVU live stream fails to capture system audio

I routinely use Snagit to capture GoToMeeting live streams. I get excellent video and system audio recordings.  So you can imagine my surprise when I recorded a 45 minute live stream aired through StreamVU (http://www.streamvu.com) and found that the audio portion of the session was not recorded. I listened to the entire session and heard all of the sound through the computer speakers, so I know the system sound was present.

Unfortunately, it was only after the session was over that I learned that what sound there was was inaudible.

Any ideas on what happened?

Hello,

That's a drag; any changes in the audio signal path you can think of? Anything unplugged? Please detail your audio chain in terms of sound card or interface box, monitoring method, Camtasia audio settings, etc. then we might be able to help better.

The recording of the GoToMeeting streams and the StreamVU stream were all made on the same laptop computer running Windows10.   Nothing changed on the laptop hardware or software other than routine system updates.  The sound coming out of the speakers was clear and loud.

Thanks for the file sample. It TRIED to record the audio but this garble sounds like some stage in the audio chain just couldn't process properly. In Camtasia Audio do you select a specific input or just go with 'record system audio'? Just curious (I never record audio in Camtasia, I bring it in ready)

If you are convinced that nothing has changed with your gear and settings, I'm thinking it is a WIN 10 update to blame. Do a System Restore to before this point and see if it all behaves properly. If it doesn't cure it, you can roll it back to where you are now.

I had WIN 8.1 issues on my laptop a few weeks ago and once Restore was completed, the desired behavior was present once again.

That is terrible audio from a Snagit recording.  Perhaps you were recording microphone rather than system audio.  See here for the difference: https://www.techsmith.com/tutorial-snagit-system-audio.html and https://www.techsmith.com/tutorial-snagit-mac-3-recording-audio.html

You can test this possibility by making another recording and then toggle from one to the other and see if it sounds the same as your bad recrding.

There's nothing I know that can fix the bad recording but if this happened to be the problem then you know what to check for the future.  If it's not the issue then I would consider contacting the TS tech support folks and see what ideas they have.
