Hey ntsarb,
Thanks a lot for sharing your experience. What I did not mention in my post is that I’m already using Cubase 11. In any case, your experience confirms everyone’s thoughts: laptops and audio recordings are not good friends, at least these kinds of laptops.
The point is that you can find an acceptable way to record with those specific configurations, but you need to “expect the unexpected” in the end.
Because of this, I ended up buying a desktop, but again it’s a shame there are no solutions.
