Well, I thought it was fixed until I started BIAB today and it wouldn't start again. Same error messages as before so I turned off my antivirus and re-installed BIAB again and installed all the update patches and I am back where I started with the sound not being matched with the chord changes in the display.
With the time difference for customer support it hasn't worked out that I can call support for their help. I tried the chat support and they just told me to call customer support.

Such is life.
