We’re on mattermost v4.1.2 and our windows 10 users aren’t receiving notification sounds. We’ve confirmed that their notifications settings are correct and they receive notification sounds for Jabber (our legacy chat tool).
Notification sounds are working through browsers, just not the app.
On Windows 10, the sound is played via a notification centre. So probably the sound might be muted by some OS settings. Would you check Focus Assist or Notifications & actions settings settings?
If this doesn’t help, can you help send over any errors you see in the desktop developer console?
