i have the exact same problems using my hp probook 440 g3, which has obviously quite the same or similar sound card. i just reinstalled windows, because i am worried by the sound that my speakers do while booting. but i have ubuntu still installed on usb stick and can give you any log output you wanna have. pls just write me the terminal commands you need.
