Cannot get Audacity to record

Audacity 2.1.3

Windows 7

I am using a Xenyx 502 recording system to make new pod cast recordings. For some reason it will not record to Audacity. I am totally stumped as to what to do.

Please describe exactly what that system is.

How is the Xenyx 502 connected to the computer?
What are you trying to record?
Where are your headphones plugged in.
Any other details that may be relevant.

I don’t know how it happened but somehow I’ve lost the record function. The sound comes through as if it is recording but the screen remains blank. I’ve reviewed all the necessary parameters. Any help will be appreciated. Thanks, Leo Shuller Cincinnati
