Saturated audio and low frequency lack

[F00lvio]

Hi,

It has been several months my notebook audio has changed even if the executable driver installer is the same as usual (sp74368 - anyway I tried other drivers and the problem persisted):

Briefly, audio seems to be over-compressed or limited thus the result is a pretty distorted version of everything, both on headphones and speakers. Plus, low frequencies are not part of the fun as they are totally inexistent.

In details, I have to keep volume tremendously low (6 out of 100 on headphones and 50 out of 100 on speakers) because it is pretty annoying and brilliant because of the lack of LF and the saturation of above.

Cue 1: sometimes, after the audio is requested for a long period (for instance 5 minutes after the start of a youtube video), audio sort of "click", changing to a more enjoyable thing with decent volume and LF back to my hears.

Cue 2: once, in the speakers properties, I had the options of many audio improvements as low boost, surround simulation and others. Now I can only change the quality. Don't know actually when this is changed but I remember that weeks ago I reinstalled windows 10 and, once the setup was completed, the default speakers properties involved these kind of stuff. After the updates everything changed again in bad.

I am pretty sure that is not an issue of the hardware because it is pretty obvious to me that there is something wrong in the audio processing that randomly changes with time or softwares.

Any idea?

Thank you for the patient 🙂
