Best bearing isolators according to redditors

The best option is to spend some money on a decent quality USB supply.(Note, the official supply is crappy!) I'd suggest trying it out with another USB supply if you have one - I find the Samsung ones are pretty good.

You probably don't need 3A unless you're attaching a number of high power peripherals to the Pi.

If this doesn't resolve your issue, then you could buy a audio ground loop isolator, that stops the leaky current from making it to the sound system. Something like this should do the trick: http://www.amazon.co.uk/dp/B000NVWB9O

Had this same issue with an older DJ controller and a laptop... it's a grounding problem with the outlet.

Get yourself a Ground Loop Isolator and the buzzing should disappear.

Britfag. Would this do the monkey?

Hola! I set all this up last year so it’s a bit rusty!

This is a shopping list for an Xbox One mixer setup similar to mine and you may need some help filling in a few gaps and the wiring!

So the idea is to build a setup to be able to use an awesome mic to talk to the stream as well as party chat ‘at the same time’ (which I prefer over using a headset) but to also be able to hear game/chat/PC audio though a single pair of headphones and control their volume levels in one place with ease.

I don't need sound going out to my PC as the Cap card is getting that from the Console via HDMI.
Streaming Xbox to PC then the WORLD!

This grabs the game audio and that’s that bit done, stream using OBS and boom!

Here's is my shopping list for party chat:

I had a similar issue to you a while back with noise coming through my amplified outputs:

http://www.reddit.com/r/headphones/comments/27dfv8/daily_headphone_purchase_advice_thread/chzti1m?context=3

I have managed to essentially solve the problem through the purchase of both ground loop isolators (any cheap ish one will do the trick), and a cheap mains conditioner.

I had the same problem in an E46, you need a ground loop isolator: https://www.amazon.com/JacobsParts-AFILTER-B-2-Channel-Stereo-Isolator/dp/B00TED5T64/ref=pd_lpo_vtph_lp_img_2/133-3835736-2006417?_encoding=UTF8&psc=1&refRID=84VZ705Z8YVY9PYJ6HF0

A ground loop maybe. If it is, this will fix it at a very reasonable cost: https://www.amazon.co.uk/AV-Link-Ground-Loop-Isolator/dp/B000NVWB9O

Update 2: I have found the cause of the problem and what was needed to fix. I will post below what i found so if anyone else gets this, they can fix it.

Everything needed to fix this in this video. It was a grounding problem caused by a crappy PC. This little box eliminated all static noises, and has actually increased audio quality. With this i also bought a 2x1/4" jack to RCA cable, as that is the type of input my monitors take, all equipment used listed here: (UK Amazon)

Like this?

Sounds like a ground loop problem... through the USB wire... and it sounds different between your laptop and desk top because one is probably shielded better..

You could modify your equipment to give it proper chassis ground..

You can buy one of these.. but they impact sound a bit.. https://www.amazon.com/dp/B00TED5T64/ref=cm_sw_em_r_mt_dp_U_f2NxCbQQ83BBX

Do some research to find out which solution would be better for you.

Ground loops work in mysterious ways, but considering all three of those components have separate earth connections, it's almost certainly a ground loop.

The ground loop probably isn't between the USB and the DAC, though - it's probably between the DAC and the speaker. Use a transformer-based RCA isolator like this - https://www.amazon.co.uk/AV-Link-Ground-Loop-Isolator/dp/B000NVWB9O (a million different companies sell them)
