Audio Routing

On this configuration page, the audio routing of all audio-related functions can be adjusted, in particular:

  • the playback devices for players, cartwall, PFL, etc.;
  • the record devices for the encoder, live feed inputs, etc.

Routing Tree

The playback and record functions are arrangend on two separate tabs, Playback and Recording, and arranged in a tree-like manner.

In particular, there are nodes/sub-trees for the general default devices, the playlists and their players, the cartwall and its players, etc.

If not specific selection was made for a particular playback or record function, the device will be displayed in gray and italics, and the default device for that audio function will be used instead. This is typically one of the devices from the Default devices section (playback, PFL, or recording), with a few exceptions:

  • The PFL device of the players and the cartwall will follow the playback/ON AIR device of the same player if not set.
  • The cartwall has a default set of ON AIR/PFL devices that will be used for all players for which no specific devices are configured.

If Regionalization is enabled, each playback function will have a separate set of sub-nodes, one for each region, where you can select the output device for that particular playback function and region.

Change Assignment

To change the audio device of any playback or record function, double-click the entry in the tree, and a dialog with a list of available devices will be presented. Select the desired device and click OK to save the assignment.

The first entry in the list – Not set (use default device) – will clear the assignment for the selected playback function, so that it reverts to the default device for that function. For example, when you clear the specific assignment for “Cartwall Player 1 ON AIR device”, it will use the “Cartwall ON AIR device” assignment again (displayed in gray).

The device selection dialog as a built-in test function that will help you to identifiy the correct input or output. For playback devices, it will output a 1kHz test tone to the sound card output selected in the list. For record devices, it will open the device and display the audio level received from the selected input in the peakmeter at the bottom of the dialog.

Errors and Warnings

Whenever possible, audio devices are identified by unique ID that is assigned by Windows by the time the device is detected/installed. This is so mAirList can still identify them even when renamed in Windows Control Panel.

There are however situations when Windows unexpectedly re-detects a device, and assigns a new ID to it. In this case, one of following icons may be displayed in the tree:

  • Yellow warning icon: The originally selected device is no longer available, but another device with the same name was found and is being used instead. You can click the Repair icon in the toolbar to clear these warnings and make the auto-selected new assignment permanent.
  • Red error icon: The originally selected device is no longer available, and no matching new devices was found. Please select the new device manually.

Load and Save

The audio configuration for playback or recording can be saved and restored to/from an .ini file using the buttons in the toolbar. Only the playback or recording part of the routing will be affected, according to the currently selected tab (Playback or Recording).
