Why is the sound in headphones different on different computers?

Question

Iron

There are the usual "droplets" and there are 2 machines - a laptop with Window 7 and a stationary computer with Windows XP. The problem is the following: headphones on a laptop give out very bad sound, while everything works fine on a stationary one. Both machines have the latest drivers for the sound card and the other headphones work as they should. What could be the problem?

Answer 1

I would say that the problem is in different sound systems, because the built-in sound cards based on Realtek chips (AC97 or HD Audio) are probably used, which by themselves do not shine with the quality of the output sound, but in combination with various variations of motherboards, they give completely unpredictable results.
But there is one "but" here - if the sound is really very bad and when you try to adjust the balance of the left and right channels, you can not hear the "shift" of the sound source, then the headphone jack is to blame. Sometimes the central (ground) wire loses contact with the plug and the headphones start working without ground on the difference between the left and right channels.

Answer 2

Are the sound cards the same? I suspect not.
Also, look at the sound settings. Maybe the equalizer is turned up, and the sound seems better.

Answer 3

Perhaps the problem is in the headphone plug, they have 2 standards, even for 3.5 mm. You can check by slightly removing the earpiece from the socket.
