I think your “GTX 1050 Ti” is counterfeit. The error you got from the 430.26 release is a pretty telltale sign, and it looks like someone doctored a GeForce GTX 550 Ti or similar to make it look like a 1050. Whoever did it didn’t bother to change the PCI ID of the audio function:
01:00.0 VGA compatible controller [0300]: NVIDIA Corporation GP107 [GeForce GTX 1050 Ti] [10de:1c82] (rev a1)
01:00.1 Audio device [0403]: NVIDIA Corporation <b>GF116</b> High Definition Audio Controller [10de:0bee] (rev a1)
So this looks like a legacy Fermi card disguised as a newer Pascal one.
I would recommend returning the card if possible and finding a genuine GTX 1050 Ti somewhere else.
