Hello @wget,
Thank you very much for your input.
What I’ve done:
- updated Windows 10 to the latest version of 1809 build 17763.437. Double check that the settings in Windows Notification and Settings were not changed.
- Killed the Mattermost process, uninstalled Mattermost desktop application, backup the data in %AppData%/Mattermost (just in case), deleted all content of inside the Cache folder, then reinstalled the latest v4.2.1 desktop application.
After trying these, I was still unable to hear any sound notification. I am not sure what other debug logs/info I should look into to find the root cause of the problem. Any ideas?
