Steven Replay Radio 9 does not appear to have the ability to setup a line-in schedule as a scheduled event.
To capture the line-in sound you will need some kind of amplification. When you connect the cable to your line-in jack to your computer my experience has been that you should hear the actual audio sound from whatever external source it is coming from within your computer's speakers. My experience only. If you do hear the external audio sound source within your computer then press enter key on the Quick Record button to start recording and to stop recording press the Quick Record button again. Also note, alt+r+s will also work to start a quick record and to stop a quick record simply press the same keystroke of alt+r+s.
