Same signal appears across inputs and outputs

Windows

There is a feature called "Audio Enhancements". This feature appears to impact the inputs and outputs of certain audio interfaces.

Follow these steps to disable audio enhancements in Windows and resolve the problem. 

• Click your start menu and type in "mmsys.cpl" without the quotations. It should display a file icon with gears. Select it or hit "Enter".
  • If this does not work for you, please open the Control Panel and select Sound (or Hardware > Sound)
• The classic Sound control panel (like Windows 7) should open
• Click the "Recording" tab, then right-click the "Line In [Device Name]" and select "Properties"
• There should be a tab titled "Enhancements" or "Advanced". Click on it, and make sure "Enhance this device" box is UNCHECKED
  • Under "Advanced", please also make sure to uncheck both options under "Exclusive Mode" - this settings prevents more than one application from accessing the audio device simultaneously (which isn't good if you are using a DAW or any recording software alongside Smaart)
• You will need to restart Smaart before the changes take effect

After this, Smaart should display the channels separately again.

Depending on the exact version of Windows 10 installed on your device, you may not have exactly the same Sound Control Panel options. Either way, there should be some sort of enhancement option that can be disabled. If not, please email us at support@rationalacoustics.com with screenshots so that we can troubleshoot further.

macOS

In macOS, we have seen two core causes for this behavior:

The first of which is Voice Isolation mode which can serve to consolidate inputs.

• To change Mic Mode, ensure that Smaart is open and accessing your device's input. An orange microphone icon will appear in the top-right corner of your screen.

• Click it and you will be able to choose between Standard and Voice Isolation modes.
  

• Select "Standard".

The second cause of this behavior that we've seen is the use of a Virtual Machine such as Parallels. To circumvent this, we recommend closing Smaart and the VM, then opening Smaart only.
