Hi Seppo,

Yep, UP2, UPX, and Chromebooks in developer mode allow to run all open- source components. We don't have in git main support for UP2, but UPX with TGL platform is supported. SOF v2.2 works with UP2.
We are developing also an ALSA plugin version of SOF. It will enable to run all same algorithms in main CPU user space without restrictions.
Not meaning to hijack the thread - but it triggered my filters because of it being a Lenovo platform and then tweaked my interest (I'm the technical lead for the Lenovo Linux program)
I frequently get complaints about the audio quality on our platforms in Linux related to Windows. I am *not* an audiophile...but I know it's something that really bothers folks.
Windows has all the Dolby audio processing which Linux doesn't get (potentially we could get it one day...but as it would be closed source I don't know that I'm enthusiastic about it anyway.
The page linked to (https://thesofproject.github.io/latest/algos/eq/equalizers_tuning.html) was really interesting. It's quite a bit outside my experience - but if there's any opinion or thoughts on if Lenovo should perhaps look at doing some internal tuning for our Linux certified platforms and how easy/hard that would be I'd be interested.
We're a small team with limited resources but....we have the platforms and I'm sure I can wrangle some budget for some test equipment and then it's just finding the time and skills needed to make it work. Is it a systematic process that can be followed or is it something where there is personal opinion/flavour that gets added and is better left alone? I don't know if it's realistic to have a goal of some equaliser files that people could use...maybe as a starting point? Curious to get input from folk who actually work with this stuff as to what might be a good target and doable (and if there is anything we can help with).
Regardless - thanks for the conversation - it's interesting to follow along. Sylvain - hope the T14 is treating you well :)
