==FAQ==
1.Is it possible to use both the onboard microphone and an external microphone at the same time (2 audio input channels at the same time)?

Answer: Sorry, it is not possible to use both the onboard microphone and an external microphone at the same time, but if you need to use two microphone, you can consider to use two X350 audio board to stack on and under your raspberry pi to use it.(actually we do not test it, you need to test it yourself, thank you!)

2.How to setup and use X350 board?

Answer: Please refer to [http://www.suptronics.com/Xseries/x300.html#MICROPHONE_INPUT_AND_AUDIO_OUTPUT here] and try it on Raspbian.
