Hi there, I bought an Lenovo W540. I am running Kubuntu 19.04 with the newest stable linux kernel. My problem is, that I miss the noise cancelling on the internal microphone which is offically supported by the ALC3232. I can not find any datasheets more(I found one weeks ago and forgot to save it). It was only software side supported. The proprietary driver (Windows) supports it well. You can hear every tab on a key on the keyboard. I started a thread on the german ubuntu forum (https://forum.ubuntuusers.de/topic/extrem-schlechte-soundqualitaet-mic). Alsa Information: http://alsa-project.org/db/?f=11daefd5b84971428bb765603344f14429c19faa I tried several ways: alsamixer, alsa modules, pulse modules,... Can you please implement this feature? Do you need more informations? Thanks
No Answer?
I don't think it's supported in the hardware level, but done more or less in software...
I already wrote its software side. How to set it up? I didn't find any option/entry to do this
It's not done in kernel. Please ask about it in the upper layer like PulseAudio or application itself.
