SOUND AND ANDRIOD NOT WORKING

Hi, i just got a chuwi tablet , dual boot, installed windows 10, which is working perfectly except for the sound. The andriod is not working.

please can any one assist with this?

I don’t know the procedure you used to install Windows, but you may have deleted some of the partitions necessary to boot Android. In addition, the order of installation is first Android and then Windows.
If you say the model and serial number I will try to get the link to download the compatible systems
