Hello, i've been battling with this mysterious hiss coming from my recently purchased and modded TPA3116 amplifier (5 channels, 4.1) form ebay, as it can be seen in the video below the hiss is very loud and very audible, i'd love to have some suggestions to fix this if there are any 🙂

What did you modded?
What happens with:
- source connected (non-grounded/grounded)
- inputs shortened to ground
- different power-supply
Can you monitor your power-rails supply to see if they're clean? Most hiss-problems are related to a bad power supply.
