Noise in headphones on a new laptop, how to overcome?

Question

Audio

There is a new laptop HP ENVY dv6-7380er, the audio was advertised as very cool. In fact ...
The problem is that there is annoying constant noise, hissing in the headphones. Louder on the left, quieter on the right. I tried everything - disabling the inputs, reinstalling firewood and their different versions, installing the default Windows driver (it didn’t work, because then the subwoofer does not work and the sound is completely flat), installing a plug on the microphone input (closing all contacts), nothing helps!
On the last laptop it was the same, it was decided by disabling PCbeep, but there is no such setting here!
You can also hear the noise from the work of the railway and the video card in the speakers.
IDT high definition
Notebook NEW. And such a trick ...
Guys, help me, how can I cope? I've been suffering for a month now!

Answer 1

Head-on solution:
1) External sound card via USB;
2) Headphones with less sensitivity;
3) Try to power the laptop in another place - a lot depends on your power supply.
4) Wi-Fi also creates a strong background: as an option, try turning it off and working.
I repeat: if you want a good sound, take a normal sound ;)

Answer 2

Heh, but you can make a huge crutch: start streaming sound from a laptop, but listen from another device. But this is already beyond perversion :3

Answer 3

Buy USB headphones - compact and convenient.
