There are often several ways to stream sound to the PC: a Bluetooth headset, laptop speakers or a monitor connected via HDMI.
The same applies to voice recordings, where the laptop’s built-in microphone, a webcam or a USB table microphone can be connected. Sometimes Windows doesn’t really know which connected device you want to use for this.
In the current Edition 6.4.3 the tool has been updated to .NET 7. In addition, the developer has fixed a bug where the keyboard shortcut did not work after restarting the PC.
