Details are valid for the standard Mumble client on Linux, version 1.3.4, English language.
If you are happy with editing INI files manually, you can use the following snippet for mumble.conf (on Linux, this file is in $HOME/.config/Mumble).
This should probably replace the [shortcuts] section you may already have in mumble.conf unless you are sure what you’re doing.
[shortcuts] 1\data=@Invalid() 1\index=1 1\keys=@Variant(\0\0\0\t\0\0\0\x1\0\0\0\x2\0\0\0N) 1\suppress=false 2\data=0 2\index=3 2\keys=105, 108, 62 2\suppress=false 3\data=@Invalid() 3\index=6 3\keys=105, 62 3\suppress=false 4\data=@Invalid() 4\index=15 4\keys=108, 9 4\suppress=false 5\data=@Invalid() 5\index=16 5\keys=105, 9 5\suppress=false 6\data=@Invalid() 6\index=17 6\keys=62, 9 6\suppress=false 7\data=s! 7\index=18 7\keys=105, 127 7\suppress=false 8\data=s? 8\index=18 8\keys=62, 127 8\suppress=false size=8
This will give you the following shortcuts:
|Mute/Unmute|| AltGr + Right Shift + Right Ctrl
(toggle, effective until you press the combination again)
|Mute|| Right Shift + Right Ctrl
(temporary mute = cough button)
|Audio Mode: Push-to-Talk||AltGr + Esc|
|Audio Mode: Voice Activation||Right Shift + Esc|
|Audio Mode: Continuous||Right Ctrl + Esc|
|Send “s?”||Right Shift + Pause|
|Send “s!”||Right Ctrl + Pause|
You will probably want to reduce the number of events that trigger an audio notification under Configure → Settings, Messages tab. Inspect the checkboxes in the Soundfile column and consider reducing the number of selected checkboxes.
If you want, you can find a sound file you like and set it in the last two entries, Text message and Private text message. Double-click the value in the “Path” column and navigate to the file. This sound file is rather quiet but unusual enough to be noticed if you remember what it sounds like.
If you prefer editing INI files manually to mouse clicking, this could work in your mumble.conf file (provided you change “sebalis” to your own user name and you´have stored the audio file in the Mumble config folder):
[messagesounds] 20\logsound=/home/sebalis/.config/Mumble/234524_4019029-lq.ogg 29\logsound=/home/sebalis/.config/Mumble/234524_4019029-lq.ogg size=29
The desktop Mumble client has a noise suppression effect that is applied to the sound you send. If you're translating remotely over Mumble, or just meeting with the team, you may want to enable this.
The settings are at Configure → Settings → Audio Input → Audio Processing. Depending on your microphone, audio setup and ambient noise, different settings may work better.
You can also try the auto-configuration assistant, in Configure → Audio Wizard. This will take you to a few steps to configure your optimal audio settings.
