All about AMD Audio Settings

The Audio group contains settings for viewing and configuring sound devices within the Control Center application. Typical sound devices include speakers, sound cards, headsets, and audio-capable displays, such as HDMI™-capable displays with built-in speakers.

Use the Default Audio Device page within the Audio group to set the default audio and communication device for your system. The default audio and communication device can be identified by the speaker and headset symbol, respectively.

Use the DDMA page within the Audio group to configure Discrete Digital Multi-Point Audio (DDMA) for an existing AMD Eyefinity display group of audio-capable displays, each with two or more speakers.

Use the Audio Delay Calibration page within the Audio group to adjust the audio delay for each display in a DDMA configuration.

Note: DDMA audio settings are only available if supported by your graphics card.

Selecting Default Audio/Communication Devices

Use the Default Audio Device page to view and change the default audio and communication devices that are currently being used.

You can select default devices using one of two areas:

Desktop arrangement area—This area shows audio-capable displays that are currently enabled and available for selection. You can select from either displays or desktops depending on your current hardware configuration.
Only displays that are capable of audio playback, such as HDMI™ displays with built-in speakers, can be set as the default audio or communication device. Displays in an active DDMA configuration cannot be set as the default audio or communication device.
Device palette—This area shows audio devices that are currently connected to your system, including audio-capable displays that are currently connected but disabled.

The default audio device is used for audio playback whereas the default communication device is used for video-calling applications, such as Skype™.

In either Standard View or Advanced view, navigate to the Audio > Default Audio Device page.
In the device palette or desktop area, right-click the device that you want to set as default audio or communication device, and click one of the following options:
- Set as Default Audio Device—Use the selected device as the default sound device for audio playback.
- Set as Default Communication Device—Use the selected device as the default communication device for video-calling applications.
Tip: To view audio and communication devices using the sound control page in Windows®, click the Open Windows Sound Panel option instead.
Click Apply.

The selected device is set as the default device. The default audio device can be identified by the speaker symbol, and the default communication device can be identified by the headset symbol.

Tip: If you want to be prompted to reconfigure your default devices each time an audio-capable display is enabled or disabled, select Notify me when audio displays are enabled/disabled.

About Discrete Digital Multi-Point Audio (DDMA)

The DDMA page contains settings for splitting one multi-channel audio stream, and routing the channels to multiple audio endpoints. DDMA requires an existing AMD Eyefinity display group of audio-capable displays, each with two or more speakers.

Use this page to configure and enable DDMA settings. Once DDMA audio is enabled, the audio delay between displays can be calibrated using the Audio Delay Calibration page.

Note: DDMA settings are only available if supported by your graphics card. Displays in an active DDMA configuration cannot be set as the default audio or communication device.

Configuring and Enabling DDMA

An AMD Eyefinity display group must be configured and enabled before you can configure DDMA.

By default, your DDMA configuration is set to stereo output. Change the Windows® Sound settings for your DDMA configuration from stereo to quad, 5.1, or 7.1 to use additional speaker channels.

Configure and enable DDMA in order to split a multi-channel audio stream to multiple audio-capable displays, each with two or more speakers.

In either Standard View or Advanced View, navigate to the Audio > DDMA page.This page is only available when an AMD Eyefinity display group is configured and enabled, and includes displays with two or more speakers.
Select displays to include in your DDMA configuration from the active AMD Eyefinity display group shown, and click Next to continue.DDMA requires a symmetrical set of displays; select displays in a symmetrical arrangement from one or more rows or columns within the active AMD Eyefinity display group in order to continue.
Note: Only one AMD Eyefinity display group on your GPU can have DDMA configured at a time.
Select Enable DDMA.The number shown on each display indicates the maximum number of speakers that can be connected to that particular display.
For each available display, do the following:
1. Click the display to configure.
2. In the channel mapping pop-up, click and drag a speaker from the box below to an audio channel on the display.
  Tip: To mute a channel, click and drag M onto the channel.
Click Test to test your audio settings.
Tip: To return to default DDMA channel mappings, click Load Default Settings.
Click Apply to save your configuration.

Once DDMA is enabled, the audio delay between displays can be calibrated using the Audio Delay Calibration page.

Disabling DDMA

Disable Discrete Digital Multi-Point Audio (DDMA) to turn off multiple endpoint audio for your system.

Note: Disabling DDMA directly does not save your configuration or calibration. If you want to turn off DDMA temporarily while retaining your settings, disable the AMD Eyefinity display group instead.

In either Standard View or Advanced View, navigate to the Audio > DDMA page.
Select Disable DDMA, and click Apply.

Calibrating Audio Delay

DDMA must be configured and enabled before the audio delay can be calibrated.

Calibrate the audio delay for your DDMA configuration if the audio is out of sync, with a pronounced delay between audio from different displays. The audio for individual displays is calibrated against an automatically selected reference display.

In either Standard View or Advanced View, navigate to the Audio > Audio Delay Calibration page.The Audio Delay Calibration page is only available when an AMD Eyefinity display group has DDMA configured and enabled.
For each non-reference display, do the following:
1. Click the display to calibrate.
2. Click Test Delay to play a test tone on the reference display and selected display.
3. Move the slider until the audio is synchronized.
Click Test Configuration to play a test tone on all displays.
Click Apply to save your changes.
Note: Audio calibration is specific to the sample rate set in the Windows® Sound settings for your DDMA configuration.
