I have googled, yahooed, and everything else to find an answer, so far without success. Basically, here's the problem. I have FSINN set up and can access MP. I can also get onto the vatsim server. I see aircraft on radar. I can access an ATC within range. I can even hear ATC and other piliot communication transmissions. But, I cannot get ATCto hear me. It's very frustrating. If you know a way, please help...thanks...btw, I am using an older SB PCI 128 sound card which works fine when I use Teamspeak with my DCA buddies for MP flights on our DCA server. So, I know that I am set up for duplex transmission, but somewhere there is a hurdle in the FSINN software and sound links that I cannot overcome. Again, the problem is that I can hear everything fine on VATSIM...but, no one is able to hear me. thanks for any help.Sherm
