How to use one soundcard with up to 4 pairs of stereo speakers

Guide on how to use up to 4 pairs of stereo speakers with one 7.1 soundcard without using audio jack splitters. If you where to use jack splitters then you could connect many more speakers. This guide is useful for those who want to place speakers in multiple rooms or for those who want to make use of multiple speaker pairs when playing audio. Below are presented multiple ways to achieve this.


Contents

  1. System wide using Equalizer APO
  2. Player specific method
  3. ASIO driver output method
  4. Xonar cards specific method (3 pairs)

1. System wide using Equalizer APO

This method affects all applications (players, browsers, games). Does not work with ASIO playback output.

  1. Set “7.1 speakers” and “8 channels” in your sound card’s control panel.
  2. Download and install Equalizer APO.
  3. Select your audio card in the Configurator window.
  4. Launch Equalizer APO\Configuration Editor.
  5. Disable preconfigured filters by pressing the power button on each of them.

  6. Add new filter->Basic Filters->Copy (…).

  7. Click “Edit text” button on the newly created filter and insert after Copy: C=L SUB=R RL=L RR=R SL=L SR=R   and press Enter.

Thanks for Matt Gore the tip.

 

2. Player specific method

Some audio players can do this with the help of plugins.

foobar2000 example
  1. Set “7.1 speakers” and “8 channels” in your soundcard’s control panel.
  2. Install Matrix Mixer plugin in foobar2000.
  3. Go to foobar2000 Preferences->Playback->DSP Manager and activate Matrix Mixer.
  4. Configure Matrix Mixer as follows:

 

3. ASIO driver output method

If you card supports ASIO output playback and the player you want to use supports ASIO output playback then you could try this method. Configuration for each player is different. Below are some examples.

foobar2000 ASIO configuration example

1. Go to foobar2000 Preferences->Playback->Output->ASIO

2. Create a custom channel mapping with the following settings:

3. Go to Preferences->Playback->Output and under Device select ASIO followed by the custom channel mapping name you’ve previously created

AIMP ASIO configuration example

Go to AIMP preferences and set these settings:

4. Xonar cards specific method (3 pairs)

Xonar cards can output audio to up to 3 pairs of speakers though the use of the drivers. This method works with any player.

How to setup:

  1. This option requires “Stereo Upmix” option to be enabled when installing UNi Xonar drivers or that you enable it in XonarSwitch afterwards.
  2. In ASUS, Cmedia or XonarSwitch audio panels set: “2 channels” and “7.1 speakers”.
