Jump to: navigation, search


Requires IOS 8.0 or later

Kazoo provides simple and intuitive way to play music all around your home.

You can view your Music sources content without stopping what you are listening to.

Kazoo has been designed to control Linn DS systems and Kazoo Server. Kazoo will also work with 3rd party UPnP/AV media servers, but for the best music experience, we recommend using Kazoo with Kazoo Server.

Kazoo is also available for Android (4.1 and later), Windows (Windows XP SP3 and later) and Mac (Lion and later).

Release history

Kazoo has support for homes that have multiple DS systems. Each system in the home should be given a unique room name. A system's room name can be configured using Linn Konfig.

Dynamic grouping of rooms

Linn DS systems provides the ability to different play music in every room in the house, play the same music in all rooms or play the same music in a subset of rooms.

All rooms grouped together play the same music in perfect synchronisation.

All rooms grouped together play the same music in perfect synchronisation.
1. Press the [Room Name] at the top of the screen
2. On the Room you wish to share to Music from press the AddSongcastRoom.jpg button (If this button is not listed then there are no rooms to group or are already setup for Permanent Grouping)
In this case share the Morning room Music ...
3. Check the rooms you want to add to the group
IPad GrpDia4-10.jpg

  • You can choose to either:
    • select and play the music you want and then group additional rooms
    • or group rooms then select and play music
  • Rooms added to a group will immediately start playing music in perfect synchronisation


If this does not work, use the Linn Konfig software and check that all of the Linn DS/DSM products have:
"Songcast Sender" > "Enabled" - YES
"Sources" > "- Songcast" > "Visible" = YES

Permanent grouping of rooms

A permanent room is a room that plays the same music as another room but does not appear as a selectable room. An example of this behaviour is an open plan area with the Kitchen connected to a Lounge. In most situations a listener would want both rooms to play the same music but be able to control the volume in each room independently.

To make a room a permanently part of a group you need to configure your Linn system using Konfig. To add a room to as a permanent member of a group you must configure the name of the room's Receiver source, (it's default name is Songcast), to be that of the group.

1. Go into Konfig and select the Room that will always be the source of the Music, we will call this the "sender" room
2. Select the Device tab and copy the "Room" name
3. Now in Konfig go into the Room that you always want listening to the "Sender" Room
4. Select the *Sources* tab in this "listening" room and select the Songcast input
5. Paste the Name of the "sender" (from point 1.) into the Songcast name
6. On this Songcast input make sure that "Visible" is set to Yes

In our example of a Lounge, called "Morning Room", with open plan Kitchen, called "Kitchen", you would configure the name of the Kitchen's Songcast source name "Morning Room". Rooms:

  • If a permanently grouped room is not playing the same as the group click SatelliteButton.pngand ensure the room is switched ON

IPad Permanent Grp2.jpg

  • The permanent grouped icon will only be visible if there is a permanently grouped room associated with the currently selected room
  • Rooms that are permanently grouped do not appear as a selectable room.


I cannot find my Linn DS

The Subnet setting in the Kazoo settings page may be confused. If you have a Subnet option, (not all iPhones/iPads have this option), Select a different address, then reselect the correct network/subnet.
If you do not have a Subnet option then check your Wifi is connected to the same IP range as your Linn DS/DSM.

Also, go into your iPhone/iPad settings and select "Mobile Data".
Scroll down the page and for Apps that can use Mobile data and disable the Kazoo app.
IPhone-Mobile data.jpg
This will stop Kazoo from using your iPad/iPhone internet when it should be using the Wifi connection.

Linn DS disappearing

IOS 11.4.1 update has been reported causing general issues with Wifi connections, this is not only with Linn DS but with anything using Wifi.
If you go into iPod/iPhone settings > Wi-Fi and switch OFF Wifi for a few seconds then switch Wifi back on then Kazoo will then find your Linn DS/DSM's.

Black screen only on Kazoo App

If you are only getting a black screen do a hard reset of the iPad:
Press and HOLD BOTH the POWER button and the HOME button until the Apple icon appears
If you have previously done a software update without fully shutting down the previous version of the Kazoo app (double press the HOME button, select the Kazoo app and slide up to quit), then the original version of the Kazoo app may be running in background while you are trying to run the new version. The hard reset will normally fix this black screen.

Linn Customer Support

If you are still having issues trying to find your Linn DS/DSM using Kazoo then you can request Linn Customer Helpline assistance. (Please make sure that you try using the Kazoo app to find and control the Linn DS/DSM first, this action will send a usage log to help us trace what has gone wrong before we contact you.)

  1. Go into Kazoo Settings
  2. Select "Report to Linn" button
  3. Select "Report a problem"
  4. Give a summary of what is not working together with your name and contact details
  5. Finally, press "Report to Linn"

You will then be given a "ticket" number for your issue. If you do not get a ticket number please do NOT repeat this action. There is a good probability that your ticket has been received but somewhere along the process Kazoo has not received the ticket number.
