Will optical audio fix ground loop? - Audio - Linus Tech Tips
https://linustechtips.com/topic/906871-will-optical-audio-fix-ground-loop/
This causes a buzz to come through the speakers when connected to an ungrounded TV (one that uses a two prong power plug). If I switch to this setup: TV > optical audio cable (toslink) > digital to analog converter > 3.5mm aux cable > external amp > bookshelf speakers. Will the buzzing be gone since the TV cannot try to ground itself through an ...
Ground Loops - Eliminating System Hum and Buzz | …

Currents flow through these multiple paths and develop voltages which can cause damage, noise or 50Hz/60Hz hum in audio or video equipment. The ground loop can be eliminated in one of two ways: Remove one of the ground paths, thus converting the system to a single point ground. Isolate one of the ground paths with an isolation transformer ...
What Is the Optical Audio Port, and When Should I Use It?

In such cases, you can often completely eliminate annoying ground loop humming from your audio system by isolating the offending device with a TOSLINK cable. Remember, TOSLINK cables are fiber optic, and because the cables are either entirely plastic or plastic and glass, there is no electrical conductivity to transfer the ground loop noise.
Q. Can digital audio cables cause ground loops?

M‑Audio's CO2 (around $60) is also a handy gadget to have, as it converts between coaxial and optical S/PDIF, and also features transformer‑isolated phono sockets so you can use it in‑line to cure ground loops. Finally, it pays to be extremely systematic when tracking down digital ground loops, as I found recently.

The ground loop is being completed by the HDMI connection where the ground isn't part of the signal. Who knows what the unbalanced audio ground inside the laptop connects to, its possible it's not even connected to the same ground as the hdmi which is whats causing the noise. I would just use a transformer isolated DI and be done with it.
Optical isolation and ground loops : Serial Data ...

Optical isolation solves the problem of ground looping by effectively lifting the connection between the data line and "ground" at either end of the line. If an optically coupled connection exists at each end, the data traffic "floats" above the volatility of ground potential differences. If the voltage potential is large enough, your equipment ...

Ground differential is technically not identical to a ground loop. For example, there can be substantial ground currents in the soil such that one side of the house is at a ground differential to the other. OTOH, you can have a ground loop with all battery powered components. This is because a loop is an antenna which can pick up hums from the air.

I have my computer audio connected to my HT receiver via digital coaxial. I solved a ground loop problem with a jenson isolator on my cable line a while back. I upgraded to digital cable with cable box and the jenson isolator is blocking access to a large group of digital channels. I know the loop problem is the computer.

It eliminated the ground loop audio hum problem, but I get no picture/sound from my PC's HDMI. I also tried DVI from the pc with an HDMI adapter, and still no picture. It did work with my blu-ray ...
Can an audio interface fix a ground loop issue? : audio

This is a ground loop, right? I have noticed a few people recommending an audio interface, and along with the other useful features it gives the main thing I'm interested in is the complete removal of the ground loop buzz. ... I've also tried connecting the TV's optical audio out to a converter box which I then connect to one of the receiver's ...
