Fix for Camtasia on Windows 11

I recently bit the bullet and updated my primary work device to Windows 11 22H2. Unfortunately, one of my most used applications did not work on the new OS. That app is TechSmith Camtasia. I tried Camtasia 2020, 2021 and 2022 and all had the same problem. I could hear the audio during playback, which made editing impossible. In Camtasia 2022, sometimes the audio would play for a few seconds or minutes and then just drop out. I found a forum that stated the March update for Camtasia 2022 fixes the issue but even after updating to 2022.4, the issue remained. I reached out to TechSmith support and was provided with steps that did indeed resolve the matter. Those steps are:

Delete the version registry key under HKEY_CURRENT_USER\Software\TechSmith\Camtasia Studio, close Camtasia 2022 and then re-open. I have been using Camtasia 2022 successfully multiple times a week over the last 2 weeks since deleting the HKCU registry for it. As is usually the case, it is suggested to export a backup of the registry before making this change but you should see the Camtasia will re-create a new 22.0 registry for you on launch.

Just an extra word of warning but if you have an application like Edge or Spotify open that can play videos or audio, it is possible that takes over the audio output channel too. If you do the registry fix and notice the audio still does not work. Check to see if another application has taken over the audio channel. A little bit of a quick workaround I have found is to toggle the Mono audio setting in Windows 11, it seems to force the audio output channel to re-initialize which will play your audio.

Hopefully this blog will save others from needing to submit a support ticket and wait for help.
