[HELP] HP Probook 450 G1 - Intel HD 4600 - Intermittent and pitched HDMI Audio until enter and exit Sleep once

[HKlan]

Hello everyone. I already tried all the possible guides, but I am not able to have working HDMI Audio on Mojave, it is high pitched and messy, however after entering and exiting Sleep once it starts to work (until a reboot or disconnecting/reconnecting HDMI cable). Is there anyone that could help me? This laptop had HDMI audio working on Mavericks.
