I just bought an Alesis Miclink. My amp only has an XLR line out, which is why I bought it. I also bought an MDB-101 "matchmaker" direct box. I hooked that up to a keyboard with a 1/4" cable leading out into the direct box and then with the miclink leading to the computer. I opened up sound recorder to test it out, because everything supposedly was installed successfully. I get a reading that i can see. After I record though, I get absolutely no sound. Not with the guitar or keyboard. I've tried on two computers. One with XP and the other with vista. same results. I've checked speakers and all connections. Any idea what the problem could be?
