Download Mumble here and install it.
The first time you launch Mumble, a wizard will pop up to help you configure your audio and mic. If not, click on Configure and select Audio wizard.
Here is the Audio wizard first page.
Default installation settings should be enough except for:
- Voice activity detection for which it is advisable to use a key to speak as voice detection parameter. This setting is called Push To Talk. Just click in the white box and press the key you want to use. In this example, it is set for space.
- Choose Disable Text-To-Speech... to disable the voice synthesis. Text-to-speech is the voice output of Mumble's Instant Messenger messages, which can be disruptive when chatting.
- We strongly suggest to use headphones for a better audio experience. If so, check the Use headphones box.
You should see this:
Click on Add New.
- Address: the server address. For Disroot, it is mumble.disroot.org
- Port: make sure the port number is 64738.
- Username: whatever you want!
- Label: the name you want to use to identify the server in your client.
Now, just select the mumble.disroot.org server and click on Connect.
Joining a channel
Root displays the list of channels on the choosen server. As you can see on the image, there are two channels at the moment: Disroot and Quarantine hangout.
To join Quarantine hangout for example, right click on it and choose Join Channel
Now you can see your username under the joined channel. You can also see on the left a message saying that you joined Quarantine hangout channel.
You can only be connected to one channel at once. So if you join another channel, you'll automatically leave the one you're in. !!
What if the channel is password protected?
If a channel is password protected, you need to create an Access tokens. To do so, click on Server and choose Access tokens. Once there, simply write down the password, validate by pressing enter and then click on OK.
You can now access the password protected channel.
Creating a channel
You can create a channel in different places:
- In Root, this is the case here of Disroot and Quarantine hangout.
- In another channel, for example here, in the Disroot channel, there is another channel called Disroot Core Sprint mettings.
So as you can see, Mumble channels can be organized hierarchically. Channels can have "Children", "Parents", and "Siblings". This can go on for several "Generations", so that one channel can be a child of a channel and it can also be the parent of other channels. The depth of this parents/children hierarchy is endless.
To create a channel, just right click where you want to create your channel: Root or another channel name, for example in Disroot or whatever channel you want.
- Name: your channel name.
- Description: if you want to add a description of your channel. It is not mandatory.
- Maximum Users: it seems pretty obvious. It is the maximun amount of users the room can host.
- Temporary: if checked, the channel is destroyed the moment the last user leaves it. Otherwise, it stays there until you decide to remove it. *Note**: this option is availble only if you're a registered user (see below).
Keep in mind that when you create a channel, you automatically become its admin.
Adding a password to your channel
At the moment, anyone connected can access to your channel. To add a password to it, first create a channel, then right-click on its name and choose Edit...
You now have the option to add a password:
Note: you can also configure groups and ACL instead of setting a password (see below).
More advanced settings
Mumble uses certificates for authentication. This allows a user to authenticate to a protected server without entering a password. The certificate is automatically created when you first join a server. It is very important that you save this certificate so that you can log in with the same username on another device.
To save your certificate, click on Configure and choose Certificate wizard.
You can see here your certificate, which is self-signed.
Just click on Export current certificate to save it on your computer.
Registering your username
Once connected to a server, you can register your username which creates a unique account linked to your user certificate. No one will be allowed to use your username, it will be just yours.
To register your username on a server:
- Connect to the Mumble server you wish to register with.
- Right-click on your username in the list of channels.
- Choose Register...
Attention: after registering you can not change your username or unregister it.
You can create groups of users. This is useful if you want to create specific permissions.
Right-click on the channel you want to create groups for, and choose Edit... and go on the Groups pannel.
- Write down the name of the group you want to create.
- The Add button will then be available, so click on it.
Now you can add members to your group. For example here, (1) antilopa is a member of the mygroup group.
To populate your group:
- Write down the name of the user you want to add. Note: only registered users can be added to groups.
- Click on Add.
- Select a member and click on Remove if you want to remove it from the group.
Groups and ACL: manage permissions
Access Control List (ACL) is a list of rules that allow sensible access with few restrictions. Most of the times, these rules will be "inherited" from the Channel's Parent. Mumble Admins can modify the ACL (eliminate/modify existing ones or add new ones).
Groups are defined or limited by the scope of the rules in an ACL. Each rule in each ACL operates on some group of users in order to grant or limit what can be done in a Mumble Channel. So, it is important to understand what Mumble's Groups are before creating ACLs.
You can set specific permission to your channels, groups and users. To do that, right-click on the channel you want to create ACL for, and choose Edit... and go to the ACL pannel.
- Here is the list of Active ACLs. The first ones are inherited from the server config and from parent channel. It is important to understand that the ACLs under are more important than the one above. So here for example, @$fb7... is more important than @all.
- Select of the ACL to check the list of permissions
- Here is the list of permissions set for @auth ACL. As you can see, some are denied, others are allowed.
- You can decide by unchecking this box that you don't want to keep the inherited ACL's
- Click on Add to add specific permission to users or groups.
- Write ACL: gives total control over the channel including changing the ACLs.
- Traverse: without this privilege, a player will be unable to access the channel or any subchannels in any way, regardless of privileges in the subchannel. Don't deny this unless you really know what you're doing; you can probably achieve the effect you want by denying a player the Enter privilege.
- Enter: allows to enter a channel.
- Speak: allows to transmit audio into the channel.
- Mute/Deafen: allows to mute or deafen another user.
- Move: allows to move a user to or from a channel.
- Make Channel: allows to create channels.
- Link Channel: allows to link a channel. A linked channel will mirror audio broadcast into one channel into the linked channel (so if channel 1 and channel 2 are linked, you can hear audio from channel 2 if you're in channel 1).
- Whisper: allows to whisper to other users.
- Text Message: allows send text messages to other users.
- Make temporary: allows to make a temporary channel that disappears when all users leave the channel.
Add permissions to users or groups
To set permissions:
- Click on Add
- Change the Context , for example if you want your permissions to apply to any sub-channels or to this channel only.
- Either select your Group
- Or select the User ID if you want to apply permissions to a specific user.
- Set the Permissions as you want and click on OK.
A new rule will overwrite the inherited one, because inherited rules are always put at top, and a new one on the bottom. So for exemple if you have a top rule set for @all to allow enter, but then in the bottom a @all rule that deny enter, then no one will be allow to enter your channel. You can move rules up and down using the Up and Down buttons.
The default groups are:
- all: everybody using this channel by any means
- admin: people with administrative authority for this channel
- auth: people that registered onto the server
- in: everybody tuned to this channel
- sub: everybody in a channel with parent or ancestor in common with this channel.
- out: everybody NOT tuned to this channel
The tilde ("~") character limits the associated group to the channel in which it is defined, eliminating any effect of inheritance or links.
- The string ($fb74c... in this example) is the channel creator id. If the user is registered, then the username will be displayed, not the id.
- #test: the password protected channel. It won't appear if there is no password set.
Set a user as a Priority speaker
Setting a priority speaker may be useful. When a priority speaker talks, every other user in the channel will be attenuated.
To set a user as priority speaker:
- Right click the username that you want to set as the priority speaker.
- Click on "Priority Speaker.
