The problem is that the BIOS has the same issues Zephkek found in other parts of the BIOS code. There are about 3-4 of them, and they're also present on his tested laptop. Zephkek, please help fix the rest of the code.

Hello everyone, thank you very much Zephkek for your work, I am writing through a translator, I apologize in advance for any mistakes! Asus ROG Zephyrus G16 (GU603VI) 2023 received BIOS update 317, there are still a lot of problems, I wanted to ask you, maybe we can fix them together with Zephkek, I Zephkek I beg you to help us, ASUS support does not hear me, but they respond to your reports, PLEASE HELP, MUX Switch does not initialize correctly and in other parts of the firmware, with the keyboard in AMBIENT mode, it stops responding for a while when switching from eco intel to two video cards and running an application on dGPU, the same problem with sound, this is shown by adjusting system sounds when resetting after a Windows reboot, it first starts on one video card and then on the other, also when turning on eco intel and rebooting, then when you turn on two video cards, the brightness control does not work, you need to reboot, I just registered I don’t know if it is possible to upload videos here, Please help!!! I can reproduce many problems with any drivers and Windows! You will also have these problems. Set the Windows power mode to Balance or Eco, turn on video or music in Browser, disable it, and open Intel graphics settings. Switch menu items, then close it. Open the Nvidia control panel and simply navigate the menu. You will see that the problem with sound switching between graphics cards is related to Balance or Eco in Windows power mode and iGPU+dGPU mode, regardless of Windows Auto or Optimus. ### I'm 1000% sure that your M16 GU604VI has this problem. At this point, the System process always spikes in Task Manager. I hope someone can answer this and help me get through to ASUS.

This... was hard to read.. I have the same laptop and nothing can be reproduced. At this point you did not even told us if you clean reinstalled windows. Nor if you installed the recommended drivers from ASUS and not updated to the latest one (for the Nvidia GPU). The latter should not be upgraded as it has problems with the automatic switching of the MUX
