Vincent Morel,

I don't have a natural setting in my Vantage... But I do have a setting to enable/disable Dolby sound. Disabling it causes the sound under Windows to sound like it does in Linux. Being able to switch back and forth on the fly with the Dolby switch in Vantage under Windows instead of waiting for reboots... The difference is more stark

However, I think I can live with it.

Especially since it looks like there's really nothing more to be done from my side at least:
https://askubuntu.com/questions/984109/dolby-equivalent-for-ubuntu

(although that link has something of a work around... I'd be curious if anyone reported back on the results).

There are likely ways required to enable Dolby in the hardware side that don't involve HDA verbs or there's a proprietary software component. Probably both.

The "good" news for me is that this is one less thing I have to worry about I guess.

Lastly, we probably have some different sound options because we're on different models of laptop. Under Dolby, I have various settings that include gaming, movies, and so on. Maybe "Natural" falls under one of the your sub settings or you have something else entirely. *shrug*

You have a 13S Gen 2, right? Could you provide your alsa-info? I haven't seen one posted for you, but there's a lot of noise (and I've just started keeping track for reference).

Thanks!
