I think there are some vstsound files missing on your computer. Can you please run the attached shell script?
First unzip it, then do Spotlight Search for Terminal.app and launch that. Drag and drop the shell script into the Terminal window and then press the enter key to start it.
After a few seconds the file VAEDiagnosticsReport.zip should appear on your Desktop. Please post that here. Thanks
