Hi, My one's internal microphone is not working. After I record videos using the webcam there's no sound at the playback. But also when I try an external mic there is the same problem. I tried all the buttons in the audio section but nothing happened. Is there anyone who could help me? P.S. A friend brought my one from Indonesia and it is AOA 110- Aw, 8GB SSD, Linux and with 1GB ram. Is it possible to have 1GB ram or the did retailer do something nice for me? ;)
