why would you not be able to plug in your mic with the tablet powered on? same with the jack. but, I digress, if you go into your program you should be able to set your default audio in device. also you can use windows sound manager. I hope this helps man!
if you cant get it to work, would you want to sell me your vi10? else, I have a vi10 that has a 100% screen, but I killed the main board 🙁 if you would like to buy dead board tablet off me
