Great it works.
The noise can have various causes.
Simple try: disable mic of laptop.
If a 50Hz noise it's a groundloop: add groundloop adapter (appx $/€ 10,-) in your output routing.
You may have an FX enabled (mixer and or Cross)
have audio/power cables seperated as much as possible.
Use a different power source (outlet from other phase)
BTW are you sure it's only the recording, or does the live output have the same?
Also check your plugs for dust and hair...
Please let's know if these help... else you may have an issue with the mixer or UCA..
