My 2 cents:
Papa is absolutely correct.
It's easy to get the input and output gain confused.
I'd like to think of working in a DAW as having three phases, Input, effects and output.
Gain at each of those steps is important so you have a strong enough signal to capture the sound but, not too much to distort it with clipping.
On the input side:
It starts with the instrument and vocal volume, mic placement and the preamp on your interface.
Before you begin recording, check the input gain on your interface, keep it just below clipping (red light).
That signal in now being sent to your DAW, so you need to check the input gain in the DAW as Papa demonstrated.
It is generally recommended that the DAW input should be around -18db.
Effects:
Next, If you're doing any effects like O/D, compression in your DAW, you need to make certain that you don't boost or cut the gain in an undesirable way. Watch for clipping on the faders.
Output:
Each fader is a separate channel sending its signal to the Main Out or stereo Bus.
At times you could have no individual fader showing clipping but the MAIN will be clipping because it's the accumulation of all channels.
You fix this by going back to each channel (track) slider and identifying the culprit.
If you use the main fader, that will remove the clipping but, it's cutting the entire session rather than fixing the problem.
@MikeS
That is very likely the situation you have there.
However, what you might have is a weak signal going to the DAW from your mic/interface.
Many mics like the SM58 & SM57 have very low output.
This generally requires the significant gain boost by the interface preamp.
Many interface preamps fall short of gain and consequently do not send a strong signal to the DAW.
There are a few ways to address this.
Think of this just like an electric guitar with volume knobs going into a pedal with volume knobs, then into an amp with gain & volume.............you need to be cognizant of every step of gain all thru the signal path.
1st try dialing up the gain on the interface preamp.
Go to the "input" view as Papa showed and try to make adjustments to the incoming gain there.
Yes, you can also raise the gain on the track as you did.
The best way though is to address this early in the signal path with enough gain to match the mic.
If the gain on your interface pre is not adequate you can add an inline preamp between the mic and your interface.
I have used these in that situation:

If you want to explore that idea, there are less expensive units on the market, search for inline mic pre amps.
