Input monitoring in logic is not showing

Hey everyone, I am having a problem with my input monitoring on each track. I had this feature working but now I have nothing and I did not change any settings.

I am using Logic Pro with the Zoom L-20 digital recorder and it can also be used as a sound card into any DAW. I did have the input monitoring working and done lots of recording but all of a sudden I have nothing. I can play back what I have already recorded but it wont show input signal and I can also hear in the headphones my new guitar signal I want to record but it just wont record or show input signal yet I can hear it sooo frustrating.

I have also checked all settings and all seems right and checked tracks to make sure they are on the recorders (Zoom L-20) input channels and thats all OK too so what could be doing this is beyond me and I really need help with it if anyone has had similar problems please chime in here. Thanks

It's not clear whether you

- have no input buttons

- can't see input signal during recording

- can't record

- can record but have no signal

- can hear guitar input through Logic

- can hear guitar input through direct monitoring on the interface

Please clarify.

Good to hear only a reboot was needed to fix the issue.

I wouldn't leave a project open for a few days, as it can create these kinds of issues with the core audio driver, sometimes extra long latency, or other malfunctions. I also recommend you never let your Mac go to sleep.
