Hi LBH! Thanks a lot for your suggestions!
How did you reinstall Pigments?
I uninstalled and installed Pigments through the Arturia Software Center
Have you tried to clean Pigments preferences through Arturia Software Center?
Yes, I did that now. The software center doesn't give any response whether it did it or not, but I guess this is the way it is. To be sure, I hit the button twice.
Are your Windows 10 fully updated?
Yes, I just updated my Windows 10.
Have you done and Windows Disk Clean that include cleaning of system files and Windows update?
Done.
Have you tried a Windows System file scan and repair - a SFC/scannow?
Also did that now. There were actually broken files that were repaired.
However, the problem still remains the same.
BTW - does it work with Windows own Wasabi driver? Look like you use the internal Windows audio soundcard.
Yes, this actually works. However only down to a buffer size of 256 samples. The latency is 5.3ms, which is okay-ish. But with ASIO4All I was able to have 0.7ms. This felt definitely better. And yes, I am using the built-in internal soundcard (Conexant) for now. Until now, it worked completely fine.
I think I will just never ever update BIOS on Lenovo PCs anymore. A friend of mine couldn't use his docking station anymore after a Lenovo BIOS update because it just wouldn't work anymore. Apparently these updates are complete garbage and mess something up instead of bringing improvements.
Edit: I was just thinking: Is it possible that Pigments just doesnt find Asio4All for some reason? Can I set something like the default path of audio drivers in Pigments? I had a look but could not find such an option.
