Bill:
You, sir, are a genius!
I could not help smiling when I read the message below. I immediately tested your described behavior and found that my “brilliant” fix for my audio problems (just starting over from scratch) was not the solution to my problem (although I am sure it helped). It was unrelated to the problem in any way.
I had been using an HDMI monitor to show the waterfall behind my laptop so that I could quickly go pick another site on the waterfall when my space was encroached upon. The video resolution on my Lenovo laptop ($349 on Amazon — worth almost that much) is not sufficient to allow me to view the main window and waterfall simultaneously on the laptop screen. But after retooling my setup and reinstalling everything, and then resetting all my radio settings (and this time saving them to an SD card!) I decided I could let the waterfall show up behind my main WSJT-X window and just pop over to it when I needed to. It has worked better and my attention remains undivided most of the time. So I planned to move the HDMI monitor to another computer for another application.
When everything worked, I assumed starting from scratch was the right solution. But I just hooked up the HDMI again, and sure enough, after a few minutes, I started having audio issues with the blasted PC. I unplugged the HDMI, rebooted, and everything is fine again.
I’m certain that Microsoft engineers read all our email and derive a good laugh when their machinations aimed at causing distress do exactly that. Thanks for sharing this observation. It was very helpful.

Hi Hans,
Windows has a nasty habit of switching
audio to any new hot-plugged device, i.e. USB or HDMI. It does
this without the applications using those audio devices getting
any indication of the audio re-routing. In theory if the audio
devices that WSJT-X is using are *not* set as the default devices,
which they shouldn't be anyway, then this nasty behaviour should
not cause a problem. Having said that there is a problem for users
with only on pair of audio devices since there is no option to
have no default audio devices so any plugged in USB or HDMI audio
device will become the new default.
The only robust solution is to always
plug in audio devices before starting WSJT-X. Another option if
you only have a single sound card is to install some virtual audio
device and make that the default device but never use it.

I am having a similar problem and can track it down to an HDMI
device. My Win10 HP PC (1909) with lots of horespower is running
WSJTX driving a TS590SG with buit-in sound card through the USB
drivers. All system sounds are using the built-in sound card
without problems.
But whenI tried to connect an external monitor throught HDMI
Win10 got confused and played the WSJTX sound on the internal
sound card although all Win10 sound settings were left
unchanged. The mess continued even after disconnecting the HDMI
connector.
I needed to restart WSJTX to rectify the situation. The monitor
connected by HDMI does not even have a speaker but it is anyway
confusing the system. Any ideas?

There is
no problem running multiple sound cards for different
purposes in Win10. I do it all the time. One sound card is
devoted to Satellite (SDRC) another to WSJT-X, another to
Windows Sounds/YouTube. Even my HiSense HDTV shows up as a
playback sound card and works wonderfully.
There is
no problem that I see doing multiple simultaneous things
with different sounds cards. As long as your computer has
sufficient horsepower, there is no reason to confine WSJT-X
to a dedicated computer.
...if you
start seeing lost decodes, that's another matter.

Just name
them and it is a lot easier to keep them straight.

That is strange

transmit WSJT-X

The only default

for both in and out audio.

You can mute system sounds, but I would not
recommend trying to run Netflix or any other music or
movie app on the same computer that you're using for
WSJT-X and related software. It's best to use another
computer/device for that.

Rick,
Do you only have one soundcard in your laptop? If
so, PC sounds (bleeps, boops and any audio that
comes out of your speakers) is also going out your
transmitter (yikes!). Also some laptops have odd
builtin soundcards.
My suggestion is to purchase a cheap USB sound
dongle. They are less than $10. Set up WSJT to use
that sound interface and then set the PC so that the
builtin soundcard is the default. Example device: https://www.amazon.com/Sabrent-External-Adapter-Windows-AU-MMSA/dp/B00IRVQ0F8/ref=sr_1_1?crid=37YT7M7ZWQE0X&dchild=1&keywords=usb+sound+card&qid=1585841829&sprefix=usb+sound%2Caps%2C189&sr=8-1

Good Morning from the foothills in
Western NC,
Recently I purchased a IC-7300 HF rig. After
setting it up as well as the WSJT-X software I
have noticed that my laptop is doing funny
things. When I start up my laptop and everything
boots up, I sometimes I might start up either say
Netflix or Amazon music and more the window so it
moves over to my monitor (via HDMI Cable). So when
those software are running on my monitor and click
on the speaker icon in the bottom right hand
Taskbar on my laptop it will show that the speaker
is set for the monitor speaker. Great. So then I
fire up my logging software (N3FJP) then click on
the WSJT-X software then JT Alert. They fire up
and I notice a couple of things happening.
1. My music gets muted a bit,
2. The WSJT people calling CQ are real slow to
respond. (Like they are not receiving the signal
from the IC7300
3. The JT Alert s cope is not right
4. When I start to call CQ and ic-7300 starts
to transmit I get the transmissions coming thru
the laptop speakers
5. When I click back on the speaker icon on
the task bar it now shows the Codec as choice of
speakers
So my question what have I done wrong in my
settings? Any ideas or suggestions?
Thank you
