1.macOS and Windows 10：
HDMI and VGA would mirror each other if you had hooked HDMI and VGA simultaneously.
2.For audio settings：
Left-upper Apple icoSystem PreferencesSoundOutput, please choose DisplayPort , then your HDMI TV and 3.5 would get sound.
For Windows 10:
Go to Right-bottom of your Window tray, find audio iconRight-click this audio iconPlayback, then you would see your TV’s information, choose TV as your sound output.
3.HDMI and 3.5 would work simultaneously.
4.If you just hook VGA and your earphone, your earphone would get sound.
5. Have tested Huawei mate 10 and Samsung S8. Both worked good. However you need to hook your phone’s wall charger(or a larger power USB-C charger, like 45W, 60W, or 100W USB-C charger) or your phone probably would restart time to time.
6. If you were using bootcamp to install a Windows 10 on your MacBook Pro, you probably noticed that Windows 10 could not detect the audio information from the adapter, you should check the Windows updates, after installed the updates, your TV would get the audio .
