I got a yamaha acoustic electric. When I try to plug into the soundcard and play, there is no sound at all, i tried both the line-in and mic-in. However, when i use a mike, it seems to be working ok. I could also use line-in and tune my guitar using audiophonics. It's just that there is no guitar sound coming out from the speaker. Is it possible to actually get a sound from the pc directly without going thru a modeling amp?
