How can I persistent the setting of the device used for input sound?

Each time when I connect my headset(MDR-1ABT) to my Mac(MacOS Sierra 10.12.4) through the Bluetooth, the sound input of device will be switched to my headset automatically, and then the output sound on headset will turn to very very bad effect(like each music or effect sound playing from very bad microphone directly rather than my Mac), then I have to switch the sound input device from headset to Internal Microphone manually to let output sound normally.

So, How can I persistent the setting of the sound input device on Internal Microphone??

Finally, It's some Application fault( on My case it's because of an Application named 'Alilang' raise this issue. when I close 'Alilang' and connect my headset everything goes well)
