That is being addressed in the next release of JTAlert.
#1 It will no longer allow use of the default sound device.#2 It will warn you
if the device changes
That should cover most bases.

Hi Bill and all,
First, thank you all for your support, it is greatly appreciated!
I think I found the source of the "noise" problem (however the "no audio"
problem still seems to be a mystery for me and many others).
what I forgot to mention was that I'm also using JTAlert with WSJT-X. It
appears that the sound generated by this application (bip for new DXCC, my
callsign, etc) was coming out the USB Audio CODEC Speaker. Turning off the
sound from JTAlert fix my noise problem for good.
I'm still a little bit puzzled regarding the "Windows 10 64-bit audio mixer"
since a lot of applications seem to appears in it without valid reason. If
someone could produce a systematic procedure to avoid sending non-related audio
to the radio speaker, I'm sure everyone will benefit since it is probably the
source of a lot of noise on FT8/FT4 bands.

Hi Fred,
thanks for that. The levels you list do not show the all the gain/attenuation
stages as you are using the 64-bit version of WSJT-X (confirmed off list).
There is an extra level slider in the MS Windows audio mixer panel for the
WSJT-X application itself, this slider is only displayed when the application
is in Tx mode.
I suspect you have excessive and unnecessary attenuation in the digital part of
the audio chain, and this may be part of the issue. The issue appears to be RF
being generated in the period of silence before the FT8 transmission tones
start, that should not happen and may be a fault in the transceiver, but before
going further with that line I suggest you try and rationalize your various
level settings to eliminate unnecessary attenuation and set the audio level
only with the DATA MOD LEVEL in your rig's menu. This post contains a procedure
that should achieve that:

Hi Bill,
I usually use around -8dB on the slider which output around 25W. I set the
Speaker output level to 50% and IC-7300’s USB Mod Level to 27%.

Hi Fred,
what level do you have the "Pwr" slider on the WSJT-X main window set at?

Ok, thanks.
You can see in the link below the noise at TX start:

which cause power overshooting at the beginning of the timeslot.

Hi,
I'm using WSJT-X/FT8 regularly for more than a year now. One month ago, I start
to notice on my IC-7300's audio scope that occasionnaly, no audio was sent to
the radio. The problem seems to get worse (more frequent) and now I'm seeing a
kind of noise at the beginning of many of my transmission. Anyone knows how I
could verify if it is a problem with my radio, the sound card (which is
embedded in the radio I think) or the WSJT-X software?
