Just bought a lexicon alpha. I installed everything, all drivers are up to date. I can get it to play audio out through my monitors but I can't get it to receive signals in. I tired my sampler into the intrument jack and got nothing and I can't pick up any sound from my mxl99 microphone through the mic input in the back, I've tried all of my audio programs, adobe,fl9,live8.1, even the cubase program it came with. I've tried every combination of settings I can think of between the settings in asio, the windows audio settings and whatever settings I could find in the audio programs. I'm running windows seven, but I downloaded and installed the new asio and lexicon alpha drivers. It can never just be plug and play can it? Allways gotta be fifty hours of trouble shooting for everything. Please help. I've run out of things to try. Thanks

First, I could NOT find an MXL99 microphone... IF you have an MXL990 microphone, you can STOP trying to have the Alpha read it because it won't !!! The MXL990 is a condenser mic and requires that Phantom power be supplied to it and the Alpha does NOT have Phantom power.
I have found a common problem on the audio interface inout is having to GO INTO the windows Sounds and Devices and verifying that under the VOICE tab, checking that the inout device is listed AND then checking the volume is turned up in that window... It seems like you have to verify everything and tweek a dozen places to get everything right to work. Having to look under the "VOICE" tab is not a good description of where the Alpha input control should be... so anyway, check that as well as it is not MUTED in that window. With Adobe Audition, make sure you set under the options, the "metering" to monitor the input recording level.
