I've done this in the past with an amplifier that I powered from the 12V supply of my computer.

If a DC/DC converter that can handle your entire amp's power is too expensive, you can alternatively place a resistor (1k or so, plus maybe an inductor / bead) in the ground line of the audio connection and use an instrumentation amplifier to recover the difference signal between the audio ground connection (at the other side of the resistor) and the audio signal lines. Depending on the power requirements, this might be a little expensive, however. Your entire circuit is powered from an isolated source then and there can't be any ground loops anymore. Given that your circuit doesn't communicate with the laptop via USB, there's no need for a digital isolator: Just place an isolated 5V DC/DC converter in the 5V power path right after the USB connector. Simulate this circuit – Schematic created using CircuitLab How is this normally done? I'm looking for a simple solution without overflowing the board with too many new components. I have used optocoupler and dc-dc isolators before, but I'm not sure how I should connect them in this context.

My question is, how can I implement a ground loop isolator for this application? I understand that a switch for lifting the ground on one side could be enough, but I want to find a solution that doesn't need a manual switch. The ferrite beads I use to separate digital devices from analogue (one side of the board is all analogue, the other digital, the ferrites go in between).
The schematics below show how I'm powering the circuit. Otherwise, it works fine (like when transmitting audio from a phone and powering it from a power bank). When receiving USB power and receiving audio from a laptop, there is a ground loop.
