I found that TedMilker's solution worked, but I would need to readjust the Volume Mixer each time I restarted. To make it permanent, I adjusted volume levels within the Windows App Volume and Device Preferences.
Taken from this post:
Settings / System / Sound / App volume and device preferences
Set Console Window Host to Zero.
(You may need to hit Tab / Backspace in the console window to trigger the bell sound before the Console Window Host slider appears.)
