# Configuring Your Computer for AURO-3D Playback

To enjoy AURO-3D content on Pure Audio Streaming, your computer's audio output must be configured correctly for your playback system. Proper settings ensure your AV receiver can decode and reproduce AURO-3D audio as intended.

### Windows Set Up

1. Connect your Windows PC to your AV receiver or other HDMI-compatible audio device using an HDMI cable.
2. From the *Start* button, go to *Windows System* – *Control Panel*. Open *Sound* settings. Right-click on your device from (1) and select *Set as Default Device*.
3. Click on *Configure* at the bottom left and select a surround sound setting, 5.1 Surround or 7.1 Surround, that best matches your system. Click *Next* and complete the speaker configuration setting.
4. Go back to the *Sound Settings* window from (2) and click *Properties* at the bottom right. Under *Default Format* in the *Advanced* tab, select the sample rate that matches the content (and select the largest bit depth). For example, for 48kHz streams, select *24bit, 48000Hz* and click *OK*.
5. Set the level to 100 in the *Levels* tab.
6. Set the player volume to the maximum level and enjoy the content.

### Mac Set Up

1. Connect a Mac to an HDMI supported device such as an AV receiver. If your Mac has no HDMI port, an HDMI adapter is needed.
2. On your AV receiver, select the AURO-3D mode.
3. In Finder, go to Applications -> Utilities and launch *Audio Midi Setup*. Open the *Audio Device* setting window.
4. Make sure that the device from (1) is shown on the left side. Right-click on the device and select *Use This Device for Sound Output*.
5. Set all of the channel volume to the maximum 1.0.
6. Under *Format* in the *Output* tab, select the settings that best match the output device and the content format.
   - Channel Number : Select the number of speakers connected to your output device.
   - Bit Depth : Select the largest possible bit depth.
   - Sample Rate : Select the identical sample rate to the content.
   - Note: HDMI ports on Apple Silicon (M1) Macs only support 48kHz output (April 2023).
7. Click *Configure Speakers…* on the bottom right. From the *Configuration* pull-down menu, select a speaker configuration that best matches your system, such as stereo or 5.1 surround.
   - Note: If your system is based on ITU 7.1ch, select 7.1 Rear Surround instead of 7.1 Surround.
8. Make sure that the channel number shown in the bottom half of the window is in the ascending order from 1~8. If the channel number is not selected or not ordered correctly, set the right channel from the pull-down menu.
9. Click *Apply* and complete the setup.
10. Set the player volume to the maximum level and enjoy the content.
