Try changing the input for your track to something else, and then back to what you wish to use. If that does not resolve your issue, please take a look at the following video.

If you continue to have an issue, please go over the steps below:
- Install the latest driver for your audio interface.
- Uninstall and re-install Studio one.
- Go into Studio One>Options>Audio Setup and verify the device that
is being used. You will then want to start a new song, create an
audio track, set the input for the track, arm the track, and try to
record. You may need to go into Song>Song Setup and verify that the
input and output audio channels are configured correctly.
- Try removing the settings files from the program and re-configure.
Below are instructions:
1. Go to Help>Open Settings folder.
2. Copy the contents of the folder over to a folder on your desktop.
3. Close S1 and delete the contents of the settings folder with the
exception of the user.license file as well as the "Extensions" folder.
4. Open S1 and go to Studio One>Options (Preferences on a Mac) to
reconfigure your settings.
5. Test to see if the problem is resolved. If it is not, please feel
free to copy your settings files back over from the backup that you
created in step 2.
*If you are missing presets or Sound Sets after doing this, simply
double-click one of your Sound Sets under Documents>Studio One>Sound
Sets.
