shutdownguard VS SoundSwitch

They won't stop everything, but also consider a collection of shutdown stoppers and aborters: https://github.com/stefansundin/shutdownguard ... https://github.com/EEDDRV/Shutdown-Guard ... and others that are not open source like https://udse.de/reboot-blocker/ ...use at your won risk. (also helps for mis-clicks in installers, or badly written installers)

What I've done before this happened: 1. Updated Windows to latest build (which is again asking me to since I restored to previous restoration point). 2. Installed "SoundSwitch" to switch with hotkeys between different sound outputs.

https://soundswitch.aaflalo.me/ can also come in handy. It can make switching sound outputs much easier (again, a key combo can toggle between several outputs).

I use SoundSwitch for switching between mt Steeleseries and speakers. I really like my headphones but find it extremely annoying they can't have a normal aux out so could just use a cable splitter. It is the reason I will never buy another set.

Download SoundSwitch so you can switch between sources with hotkeys.

If that doesn't work look at your Sounds/Recording settings and make sure the mic is the default input device. Then (IIRC the nano also has audio passthrough) if you are 'monitoring' or using the sound card in your mic for output make sure it is the default Playback device. I suggest using a free utility that will let you toggle through between your default outputs and recording devices with a keyboard shortcut called SoundSwitch, so you don't have to go into your sounds control panel to change default devices.

I used to use Soundswitch. Pretty good program :) https://soundswitch.aaflalo.me/
