Black Screen on Lenovo IdeaPad 4 10

[p3z16393]

Title pretty much says it all.

No audio heard from running a game (in my case, Dissidia).

Gist of the device:
- Android Nougat 7.1.1
- SND 425 1.4GHz Quadcore (64-bit)
- 2gb RAM

Already played around with the settings, no dice.
Used a setting setup that worked for another phone (Asus Zenfone Max Z010D), didn't work as well.

Any recommendations?
