Alas, no, I really have the AX500. The AX1650 is waay much more well 
behaved and it is the one that is usually shipped on XPS developer edition. 
Unfortunately XPS developer edition does not have a 32GB RAM option, which 
was absolutely needed for me, being Qubes unbelievably ram hungry. So I was 
forced to purchase the model with the Killer AX500 T_T

The sad thing is that audio worked perfectly on kernel 5.4... I'll try to 
give a look to this by the end of the week, when I'll have a bit less work 
to do  :)

That would be a wonderful, wonderful thing. In the meantime I'll try to 
learn how to compile my own kernels, my pc also tends to heat quite a lot 
and I suspect that a taylored kernel could make my overall experience 
better, correct me if I'm wrong... :)

About awokd suggestions: I tried to install 4.1 but the installer doesn't 
boot on my machine. Also, I've always been very unlucky with Qubes backups 
(traditionally I do them and they never work on restore), so I'd gladly 
avoid having to reinstall everything right now...
