Noise cancellation not work for Alsa

[omixam]

Hello,

I installed Alsa and configured my audio sound, but it has a horrible noise.

The noise is more notable when I connect earphones.

I read some about this issue, but the solutions are given to pulseaudio not for ALSA.

Any idea How can I solve this problem?

difficult to say when we can't hear it.
i never heard of LINUX producing noise.
i also never heard of a noise cancellation module for alsa (or pulseaudio)
in other words, without additional information, my guess is hardware problem.

I tested the same hardware under other OS (Windows) and not present noise, hardware problem is discarded.

Let me know what type of information or output can help to have a better understand of th issue.

Try run alsamixer, select your sound card, press F5 and try find the noise source - microphone, Line, which Input is selected.
Microphone also depends of Boosters.
