Can't lower/mute sounds after most recent update

I thought this was an issue with my PC but after updating NT on my laptop as well, I’m having the same problem. I watch videos while I trade and I like to lower the sounds on NT or mute them. But no matter what I try to do (I have even went into the NT folder and deleted all sounds), the sounds play at full blast.

Just to be clear, I have hit the X on every sounds in In the Settings > General > Properties section. I also lowered the volume to 1 to see if that would help but no luck. Even muting NT in Windows mixer doesn’t work. It’s very strange.

Any other way I can control these sounds?

Report a bug, and tell them how to repeat the process. There’s definitely a few sound related bugs in the latest release,
