Hey there.
I have an Acer Aspire VX 15 (VX5-591G-75RM) which is having issues. I have owned it for several years and all of a sudden multiple issues popped up at once.
Sound:
The speakers don't work (neither do headphones) and when I try to open Dolby Audio it says "Your installation is missing components. Please reinstall the audio driver..."
However, when I install the audio drivers from the Acer site here, nothing changes.
Fans:
The cooling fans sound like they are at maximum at all times. This is a new issue, as they used to stay quiet until a load is placed on the system, but now with nothing happening (confirmed with task manager) the fans are roaring at maximum.
I have tried several things. I reset the operating system, keeping my files. Then backed up my files and completely removed and reinstalled the OS. No change to either issue.
Next I installed Driver Easy and updated all the drivers (there were a bunch needing it) but no help from that.
I have tried the audio drivers from Acer after doing all the previous steps, no change.
Any advice would be helpful, I'm out of ideas

FAQ & Answers
Unfortunately the restore points are all for earlier today, and I have been trying to fix this for several days.
Another issue I discovered while looking for a solution is that the dedicated GPU isn't showing up in device manager (and I have show hidden enabled). Seems likely that is part of the issues with the fan. In the last 30minutes I intalled DDU and removed all the Nvidia/Intel/and Realtek drivers, but have not reinstalled any of them yet.
I have installed and uninstalled the Intel graphics a couple times so far
I had been using DriverEasy to install the Intel VGA Driver, so I went back to Acer to install it. I accidentally installed the IRST (Intel Rapid Storage Technology) and decided to run it anyway. I ran the setup, It prompted to uninstall. I chose to continue, and after restarting the computer the audio is back!
I reinstalled the IRST from the same download and the audio is still there! Nice to have something working again. Going to try the Intel drivers now.
Also I have tried installing the Nvidia drivers from Acer, they failed saying the correct hardware wasn't present. I will try again after the Intel drivers though.
Now the last issue is the NVIDIA installer failing. The error message is "The graphics driver could not find compatible graphics hardware"
I went through the Acer website drivers and freshly installed all those that seemed related to hardware functionality, then tried the NVIDIA VGA drivers again. Same error.

This driver specifically https://global-download.acer.com/GDFiles/Driver/VGA/VGA_NVIDIA_24.21.13.9826_W10x64_A.zip?acerid=636667270546914531&Step1=NOTEBOOK&Step2=ASPIRE&Step3=ASPIRE VX5-591G&OS=ALL&LC=en&BC=ACER&SC=PA_6
No matter here I check there is no trace of the GPU, but I suppose the same thing was true for the audio systems before and now they are working fine...
