Hi Jerry,

What interface are you using, and which version of protools?
There are different ways to do this, depending on what you have.
Assuming you are on protools standard (not HD, not CPTK, no green 'I' button next to the record-enable and solo buttons) you might want to check under the options menu and play with the auto-input/input-only option.

Hope this helps,
John
