Trying to configure Multi Room Audio Player zone, you can notice that your sound device is running in stereo instead of 5.1 or 7.1 channel mode.
So you need to change sound device setup to use more channels.
You can setup sound speakers in different modes – stereo, 2.1 or 5.1 Surround and more. The easiest way to test (or change) it, is a right mouse click on the speaker icon on your task bar. Please select “Palyback devices”. Of course you can open sound settings via Control Panel too.
At first, you need to disable all audio enhancements. Please select your Playback device and press “Properies”. Then select “Enhancements” tab and disable all enhancements. Press OK.
Now click on “Configure” button and choose desired speaker configuration. Test it! Then press “Next” button and follow the instructions. Your new audio speaker setup is ready to use.
And now we need restart Multi Zone Audio Player or press “Refresh” button on “Audio Devices” window. After re-initialization we can use all six (or more, depends on your audio device)) channels instead of two in stereo mode.
So be careful. Always check sound settings after installing a new audio device.
