FWIW ... its a Windows issue, so I expect the clone to have the same
issue if its staying on the code base.

So the interesting thing is that this *never* happened previous to
WSJT-X v2.2.0.  I've been running this hardware setup for nearly two
years.

Also interesting is that merely shutting down WSJT-X and restarting it
resolves the issue.

I have to see how JTDX behaves.

    It has to do with Windows shutting off sounds.  They assume that
    if you put your monitor to sleep surely you want all of your sound
    devices to sleep too.
    That's why I use the power button on the monitor and have no
    problems that way.

    Microsoft has no concept of audio other than speakers and
    headphones.  Been trying to get them to put a "leave this audio
    device alone" checkbox or such.  No joy and probably never will be
    since we hams number in the 10's of thousands compared to the
    millions of speaker/headphone people.

    Hi Steve,

    I am not exactly sure how to stop it happening, but an HDMI
    monitor going to a power saving mode causes USB devices to be
    re-enumerated. That happens without WSJT-X getting any
    notification, and a selected USB audio device can suddenly become
    a different device. It may be something to do with HDMI providing
    a USB capability.

        Hi Steve,

        is your monitor connected via HDMI?
