Google has not provided any option to turn off sound in the Hangouts… is it possible to do so?
You can just disable access to the sound file so that it does not load at all.
Great idea! I just tested it, and seems to work on the web interface. Since I don't chat via the hangouts plugin, its good enough for me.
You cannot turn off sound notifications in Hangouts.But,you can snooze it off.
Another way could be going to sound mixer options in notification bar(Windows 7 and above) and muting sound from Firefox.Although,this would mute any other sound from other tabs too.
I had already read that article, and it was not what I wanted to do.
I was looking for something like Sk's answer. Disabling access to the sound file seems to work for now. Thank you for your help.
Google hasn't added the option yet. But you can disable the sound notification by disabling access to the sound file.
