2. Check mono audio setting. In the iOS setting -> accessibility -> mono audio, make sure it's off.
3. If you are using external speakers, please select speaker mode in the Setting -> Output Selector -> Speaker. Or try to use a stereo cable but only plug left or right into your aux-in or line in.
Note: If your interface has 2 outputs, use 2 cables - a Stereo Cable (One jack that splits to Two jacks) will give you a much smaller output sound.
4. If you are using an USB input adapter, try to change the input channel setting to a different channel (Settings -> Input Channel)
