Ok, I use the Lexicon Alpha to record/broadcast on Ustream. I broadcast live on Ustream and I record using Adobe Audition.

Since I have upgraded to Windows 7,(note: the Lexicon was working fine on Vista for months) my XRL mic is not getting picked up by Ustream and Adobe. But when I broadcast or record,whatever is plugged into the Instrument jack (in the front of the Alpha) does work. But again, the XRL is not picked up by either the Ustream or Adobe.

Also, when I right click on the sound in the taskbar and click on the Recording devices, the Lexicon Alpha mic level goes up high when I speak into it.

I hope you can help me.

Also, I have set the Lexicon as my main recording device as well. Like I said, this worked fine for months on Vista.
