Noise in headphones?

Question

Sound cards

I'll warn you, I'm sober and sane.
There is an annoying noise in the headphones all the time. The headphones themselves do not make noise if they are connected to a mobile phone, for example.
Those. noise from the audio card. However, there is one strange feature here. The noise stops while scrolling pages in browsers (in Opera, if you turn the wheel back and forth, then there is no noise at all. And in chrome it becomes intermittent). When moving the mouse (even if it rests on the screen), the noise becomes stronger and acquires a higher frequency character. Pressing the keyboard also makes changes to the noise: if you hold down and hold, for example, the spacebar, then in the headphones, it’s as if they are shooting from a very quiet machine gun.
The real question is: what the hell?

Answer 1

probably some interference from the FSB (as I understand it, integrated sound), respectively, any load on the bus causes a change in the nature of the interference. Try to plug in a non-integrated sound, I think the interference will disappear.

Answer 2

It was somewhere nearby. Turn off the CD-line or whatever it is in the sound system. If Windows and realtek sound, then connect the headphones not as headphones, but as front speakers. Realtek will not amplify the signal and these high-frequency things will be less audible. I also have them, under Linux, but quieter. But I have them because the headphones are connected to the front panel, and there the unshielded cable goes. If you connect back - everything is ok.

Answer 3

Only the lazy did not ask this question on the Internet.
1) Check if there is a cord from the CD-DVD device to the sound system, if it does, pull it out.
2) If the headphones are connected not directly to the sound system, but to the front panel output, try connecting directly to the audio card.
3) Change the integrated sound to external.

Answer 4

In fact, there can be quite a few solutions ... cases are unique everywhere.
I myself faced such a problem, only the truth was the difference. When turning pages, the noise changed.
I solved the problem by replacing the sound card with a good audio interface ... and I don't regret it at all.
Although, as far as I remember, in most cases, turning off the microphone input helped ... they say it was he who was phoning.
But I strongly recommend taking something like e-mu 0202 ... you will feel the difference in quality very much. And the problems will disappear ... unless, of course, you are a Linux user :) there are problems between e-mu 0202 and linux…
M-Audio delta 66 itself, the computer is used as a media center with large outdoor speakers.

Answer 5

Is the computer grounded? :) There may also be a power supply, tk. the audio one is powered not from the motherboard converter, but directly from the PSU (via the connector on the motherboard) ...

Answer 6

I have this, only when I download over the network with a speed of more than 5mb

Answer 7

A sound card can have multiple inputs and multiple outputs. You can try to open the mixer and disable unused inputs / outputs programmatically. That is, turn on the music, output all devices in the mixer, turn off everything except what it doesn’t play without

Answer 8

Headphones with a built-in microphone? If so, try grounding yourself by placing your fingers on the outside of the USB extension cable.

Answer 9

I myself was tormented by a similar problem on a laptop (Asus f7sr), an article appeared on Habré once with an overview of one of the possible causes and a way to fight, more options were thrown in the comments. I was noisy under XP and not noisy with the original firewood on the OEM Vista. I didn’t find any quiet firewood for XP, the transition to the seven didn’t help either, as a result I changed the entire unit, since the time was approaching the planned replacement.

Answer 10

There was a similar problem (at the same time, it was not solved by manipulating the mixer and turning off any Line In, Mic, etc.), it was solved when installing fresh firewood almost 3 years after the release of the motherboard (Asus p5b-e plus) :D

Answer 11

In the power settings, you need to set the "High performance" plan, it helped me. The reason was in nvworld.ru/faq/disable-powermizer/ That is, with a standard power plan, firewood for vidyuhu reduced system performance, which also affected the sound (clicks).

Answer 12

Guys, on my laptop it helped to solve the problem in several ways. This is a change in the power management scheme from "balanced" to "high performance" (click on the charging icon, if not - RMB -> Power), and also just connect the laptop to charging :)))

Answer 13

I just searched the Internet for an answer to a similar question. Only I have headphones connected directly to the sound card at the back. Sounds began as if I drive the mouse on the table twice in a row. I found the solution in the sound drivers settings (I have Realtek HD). In the "Sound effect" tab, the item on the right "Loudness" was checked. Unchecking these strange sounds as if by hand removed. The sound quality was not affected in any way. Maybe this will help someone, since it helped me.

Answer 14

helped me:
1. go to the website of the manufacturer of your motherboard
2. download the latest bios / ufi (for your card)
3. install it
4. lower the processor frequency in the bios to default (it was configured above)
5. before it became so intrusive that I got into the BIOS, updating the system and drivers helped, but only for a while
ps: I had a similar problem earlier, the squeak appeared from the movement of the mouse, this was especially evident in 3D applications ... well, it was obvious to update firewood to Nvidia, in my case it was necessary to install a different version
