I have Ubuntu 18.04 LTS and i installed Viber for linux. Everything's working fine, but when i got a new message for example, the notification sound is not clean and seems like a "crash" and didn't find a way to disable the sound of viber notifications.
Can someone help please? Thank you
Perform the following steps:
Settings → Sound → Sound effects
and turn off
Alert volume
?.If you just want to turn off the sound for one application you could also go to:
Settings → Notifications
and select your application and turn off
Sound alerts
.
