Since a few days I have also had problems with the audio alerts via JTAlert. Possibly after a Windows 10 64 bit update.
According to my observations, this seems to be a problem of Windows 10 and not of JTAlert, because I haven't had any audio output outside of JTAlert since that time.
I remembered many weeks ago someone suggested a solution. I have implemented this.
What have I done?
I installed a cheap USB sound stick (less than 10 US $) and declared this stick as the default device in the sound mixer. The stick is not used operational.
After that I get audio alerts from JTAlert again via my Realtek High Definition Audio device.
Maybe other JTAlert users can solve the sound problem in this or a similar way.

Jacek, thank you. I would try that if I had a Realtek analog audio output. On my PC I am using the optical digital output on the soundcard to the optical input of my speakers. So there is no other Realtec output (See below) and I have already tried them all. And the current audio set-up works wery well, except for the updated release of the JTAlert software. The JTAlert software doesnt show up as an application in the volume mixer. I suspect its not operator error, but a change in the JTAlert software is preventing JTAlert from linking with the PC's audio application.
In bullet point form because it is easier to read/follow...
- There were no changes to audio management in the recent release. There haven't been any changes for several releases.
- Application volume sliders appearing in the Sound Mixer are controlled by Windows, JTAlert has no control over that.
- The main JTAlert.exe executable doesn't perform any audio playback and will not appear in the Mixer.
- All JTAlert audio is managed by the "JTAlertV2.Manager.exe" process and it is this process that will appear in the Mixer.
- Application volume sliders in the Mixer will only become visible once Windows has detected a sound-play type event from the application.
- An example from my Realtek (digital) output tests ...
- Mixer before first sound is played from JTAlert.
- Mixer after Windows has detected the JTAlert sound-play event.
- To make your life easier, you can perform Sound Output device changes and play tests from the main JTAlert window without having to open the Settings window. Via the "Sound" menu.
- I suggest you try tests against other Sound devices regardless of whether they will produce sound. Just a test to see if those devices will show "JTAlertV2.Manager" in the mixer after a test sound is played.
- If "JTAlertV2.Manager" repeatedly doesn't show in the Mixer for other audio devices then the likely causes are your PC protection software interfering and blocking the UDP control message sent from JTAlert to the Manager process, the "JTAlertV2.Manager" itself is not running or the Audio module of the Manager is not initialized. You can check the status of all Manager modules via the JTAlert "Help -> About" menu.
If you still can't resolve use the "Help" (or "? ") -> "Contact Support" menu, on the main JTAlert window, to send me your JTAlert files for analysis.
