now good question. I have rog ally conected to monitor by HDMI and as monitor do not have speakers i use sound bar conected to monitor headphone jack. this odd setup because on same monitor conected my desctop by display port. and it gives me audio same way. so on hdmi and display port they transfer analog audio or there is DAC in monitor?

my 5400 rpm drive, yup they sure are.

as a person who plays guitar, using distortion or overdrive, this problem multiplies (literally) and can be a great source of frustration but if you know what you are doing, a lot of interference can be mitigated. the only part you are stuck with is the internal components picking up natural background static (they grey snow on a TV with no cable) and amplifying that. (we don't live in faraday cages.)

"Coated in a chemical called photoresist" Oh cool, whats that do "Afterwards....." Oh so your not going to tell me. 10/10 educational video.

A good quality 'Ground Loop Isolator' is the easiest way to eliminate ground loop noise. Any time I encounter a loop issue, that is my goto solution.

Threadripper is a pretty beefy cpu

Balanced cables are an easy solution to ground loops, but it seems like some noise floor is just a fact of life with powered speakers. Neither my Yamaha HS8 or Presonus Eris E5 XT are silent.

Your local Ham Radio enthusiasts isn't likely to be a source of interference. But they'll know how to track it down, or as least get you some ferrite cores to help cut down on RF induced interference... You should get a ham radio license.

I'm surprised they didn't mention the usefulness of ground loop noise isolators.

I can't stand the hissing noise. Mine was caused from a ground loop capturing audio from one PC to another and yes they were plugged into the surge protector. A ground loop isolator fixed my issue.

Are they experimenting with the end cards at earlier times? Is it a mistake? Or am I dumb and they've been doing it that early far longer than I realized? I've only noticed over the last few days..

Didn't expect to see GL.iNet as a sponsor. I got one of their travel routers for work and hotels. Pretty capable little box.

becsue stupid people buyig them so expensiv

Hmmm, james talking down to the audience again. No thanks.

I have this issue but it becomes very apparent to my 5.1 surround when I turn off my PC. I think it has to do with my shitty receiver. There's just isn't any good and moedrately affortable 5.1 system for PCs. I was searching for the RF filters you mentioned and led me to Ferrite Beads. Are those a cheaper solution than adapters?

I found it sad that you portrayed the ham operator as an inconsiderate neighbour. Most hams will happily assist in solving any kind of RF problem be it from their transmitions or something else.

Exuse me sir, us ham radio operarors follow part 95 of the FCC rules and we do not cause harmful interference and if we are made aware of interference we help fix the problem. Maybe you were referring to cb or just LED lights causing harmful interference! GOOD DAY! JK but really we are generally a helpful bunch.

How about a video about ethernet over coax / MoCa, I think that could be kinda interesting!

How to stop cobra chickens from hissing

powerline... /longsigh ... Still waiting for a better alternative for my room

What happened to the time stamps

If your amplifier even has a ground, you bought garbage equipment! Good audio equipment don’t come with grounds at all because they are internally insulated and safe. Also this explanation of a ground loop is not correct it’s about the different circuit, but more specifically the circuits must have separate grounds and separate potential differences. Some circuits can share a ground inside the circuit (all circuits eventually go to the same place though). It’s more about the potential difference not the fact that they are separate

4:06 I have a pair of those headphones, Senheiser hd205 the worst headset I've ever heard, it's on par with those ultra cheap 50 cent Chinese no brand earphones. Absolutely devoid of bass so only good to listen to and justice for all our an audio book lol but make sure it's a short one because they are super uncomfortable to wear for more than 5 minutes. I can't believe Senheiser put their name on those things. Never buying anything from them again.

This video couldn't have been more perfectly timed for me.

Ground loop... Holy fuck you might have solved my problem... Nope, my left channels just fuckered.

Crackles, discontinuous, interrupted or explosive sounds, are worse than hissing!

Ground loops are the bane of my life.

Ground hum isn't caused by using different outlets. It's from using outlets grounded on different circuits. Outlets across the room from each other can be on the same circuit while outlets right next to each other can be on different circuits. Think in terms of which outlets share the same circuit breaker. It isn't just audio devices that cause the problem or experience hum. Hum can also be seen in televisions and projectors as a line slowly crawling from the bottom of the image to top. Hum is induced when devices connected to each other through audio and/or video cables are plugged into different circuits. When you're using multiple devices connected to each other through audio or video cables, you want to get them all grounding in one place. If you can't get all your devices on the same circuit, there are devices that can be installed in the system to fix the problem. The most common method is called a ground lift, which is cheap adaptor placed on the end of a power cable or in an audio line. Install the ground lifter on one of the interconnected devices and it disconnects the ground wire from that device and prevents it from grounding through the circuit it's plugged into. This forces it to ground via the video or audio cables through the other device it's connected to which doesn't have its ground lifted. Ground lifts are quick fixes but can damage equipment in the event of power anomalies. Still, you will generally find them in the toolkits of professional technicians and used regularly. I've been doing it for twenty years and never had a problem. There are more expensive electronic devices like isolation transformers that condition the power without having to lift the ground. Some devices have it built in and offer a switch to activate it. I work in convention audio visuals and this is an extremely common problem as we work in different venues every job, are at the mercy of whatever power is available at those venues, and generally divide our audio, video, and lighting systems up over different legs of power. A lot of audio visual technicians don't understand ground hum or know how to fix it and can be the hero of the day when they do.

When your pc blue screens so hard you can’t even run diagnostics without it blue screening

Recall when you would have your phone near your speakers and you'd hear the "BRRRRrrrr ta ta ta taaaa" on your speakers before you'd get a text message?

Windows Vista was skipped from that list

Apple SoC - did you forget about me mate?

Guys am i tripping balls? Google says the russia ukranin war started 20 February 2014 but i could have swarn it only started like 3 years ago.

Ive had russian voices come through my xbox 1 when it was only plugged into the wall.

The fact everyone wasn't using SCART when it came out, is a travesty and a sin upon mankind.

More Windows NT than 95 in it. WIndows 95 was just a mess, porting Win32 onto a DOS based Windows. And yes, the idea was as bad as it sounds.

omg ive been trying to fix this issue with my speakers for the longest time

If you have identified EMI as the source of the noise, try switching to a balanced connection. Short circuit has covered it before, but the TLDW is it works by sending an inverted signal along with the regular one. When it gets to the other end, it is inverted again. Any differences can be filtered out by comparing it to the original signal. Anything professional like XLR, TRS, or Twist-lock cables can be set up for balanced signaling.

thank you bro your explanation was easy to understand

Doesn't ground loop happen from outlets on different circuits, not just because they are different outlets?

Because theyre alerting you you're on their territory

Such an extremely useful video. Studying for the CompTIA A+ right now and this video greatly helped me understand things that were not discussed and clarified in the actual A+ study material (looking at you Mike Meyer's).

Okay, one of the most obvious reason was omitted - POWER SUPPLY! The cheap chinese switching ones are one of the worst and can ruin the best audio electronics listening experience. Btw ever heard of audio-graded switching and non-switching power supplies? Transformator ones for example? Still used, for very good reasons. LP filters as well are very much needed. And yeap, that would be nice to mention why there are these "weird thick cylider things" over cables in some electronics.... ;)

Womp womp 4 years later and we now have an epidemic of terrible PC ports with DX12 ultimate being the primary reason why. As someone with a 3080 and older cpu, whether or not a game uses DX12 ult will determine whether i get over 100 fps or hardly even 40. Fuck dx12 ult, developers PLEASE stop using it

You forgot about gain stage. If you for example have an amplifier connected to your computers 3.5mm output and have the amplifier at max volume and the computer at low volume that amplifier is going to amplify the noise of your computer by a lot even if the music is playing at low volume. So if you instead lower the volume on your amplifier and turn up the computer you won't have the same amplified noise.

The RF filters shown at 3:36 are indeed RF filters - just for professional wireless microphone systems. They are UNSUITED to fix any home audio issues. I would strongly recommend to put a disclaimer at this part of the video. It creates the impression that you could buy these to fix your issues at home. Additionally the most common problem is not part of the video: gain staging You should go through each component of your setup individually and check, where the noise is coming from. Hissing powered speakers might be perfectly usable, if you turn them down a little bit and increase the volume in Windows or on your interface instead.

You missed noise generated by amp clipping, mostly occurring in car audio systems.

My SteelSeries Arena 7 does not have this problem but it is also expensive. Ever since I knew FaZe Clan I bought the prdoducts they use. At first it was Turtle Beach but they alway broke very fast and weren't good quality even the non cheap one. Then they switched to STeelSeries and I have never lookes back. I own like every single SteelSeries product or at least one or two of each kind from the most expensive kaliber. I love SteelSerie and although they are quite expensive sadly, they have very good quality and I can seriously recommend them to anyone. Before SteelSeries my life was pain. But then STeelSeries came and made my life so much better. I am sure there are other good brands out there making tuff, but for me it is Steeleries literally all the way.

"Be sure to read reviews." Okay, but audiophiles literally don't understand how digital audio works, pay $200 for a basic cable, and don't understand the placebo effect. These people pay $25,000 (yes, that is the correct number of zeroes) for a basic NAS that doesn't offer redundancy. So keep that in mind.
