I'm still a little bit puzzled regarding the "Windows 10 64-bit audio

benefit since it is probably the source of a lot of noise on FT8/FT4
bands.
Hi Fred,
there are two options:
If you only have one sound card then all system sounds must be disabled
otherwise they are liable to be transmitted on air.
If you have a separate sound card for your rig then that sound card must
never be set to the Windows Default sound card nor set to the Windows
Default Communications sound card.
An application will appear in a Windows Audio Mixer when that
application has selected the mixer audio output device for output. Note
that there is a Windows Audio Mixer for each audio output device
(Speaker in MS Windows audio terminology).
