Hello Ramesh what kind of device install log file do you mean? I'm unsure of what you are saying
I've mentioned the log file path as well. Please upload that file in your next reply.
It says its too large Ramesh. What do i do? I also have 2 set ups this day do i select the one before i tried to update again? thank you.
Can you please share it on WeTransfer.com or GoFile.io and post the link here?
https://gofile.io/d/sUgAYop4 here is the go file link ramesh
Please unzip Audio_Realtek_6.0.9912.1_W11x64_A.zip (the package you downloaded already) to a folder on your desktop.
Let's say the folder name is Audio_Realtek_6.0.9912.1_W11x64_A.
Move the folder to the root of the C: drive.
Open Command Prompt as administrator and run this command.
pnputil /add-driver "C:\Audio_Realtek_6.0.9912.1_W11x64_A\Audio_Realtek_6.0.9912.1_W11x64_(ALC245)\Win64\*.inf" /subdirs
Post the output here.
Update:
The command-line has been modified. Please refresh this page.
Hello Ramesh, I have a question is it supposed to have 188 only instead of the toal of 209, please check the file below.
drivers.txt
Edit:
Also Ramesh the zip file acer made me download was 6.0.9514 could this also be another reason why there are failed commands?
From Command Prompt admin, run:
reg add "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Setup" /v "LogLevel" /d 0xffff /t REG_DWORD /f
pnputil /add-driver "C:\Audio_Realtek_6.0.9912.1_W11x64_A\Audio_Realtek_6.0.9912.1_W11x64_(ALC245)\Win64\*.inf" /subdirs
Post the output of the 1st command only.
Once done, attach the latest setupapi.dev.log file. Don't attach the archived file (i.e., archived ones have timestamped file names).
Hello ramesh here is the output of the command that you replied to me.
Here is the setup papai link: https://gofile.io/d/Wg5E2RHs
edit:
ramesh i accidentally pressed enter in the command prompt the command continued and the one applied is still 188
C:\Windows\System32>reg add "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Setup" /v "LogLevel" /d 0xffff /t REG_DWORD /f
The operation completed successfully.

Hello Ramesh, Is there any way of contacting you tomorrow? if so could you please provide your social media if you have one. I still have to go to school at 6 AM. Thank you.
Some built-in Windows drivers required by the audio driver packages are missing.
Please run:
DISM /Online /Get-Drivers /all /format:table
dir c:\windows\system32\driverstore\FileRepository\*.inf /s /a
Copy the output to a text file and upload it.

I'm subscribed to this thread and will reply as soon as I see your post. Please take your time. 👍
Hello Ramesh Here is the response for the first Command.drivers.txt
Here is the response for the 2nd Command: drivers2.txt
I only have 6 gigabytes of storage left.
I would only be able to respond until 1 am. I will be able to respond again by 12-1pm after classes. Thank you
Run:
pnputil /add-driver c:\windows\system32\driverstore\FileRepository\ks.inf_amd64_3d416c2f26333f02\ks.inf
pnputil /add-driver c:\windows\system32\driverstore\FileRepository\wdmaudio.inf_amd64_b22af218c97c4722\wdmaudio.inf

Is it okay if I shutdown my laptop? I really have to sleep, I will give you the response when I get home from school
Yes. You may shut down the computer. When you're back, post those outputs.
I really have to sleep, I will give you the response when I get home from school
Ok. 👍
Ramesh i already close the commnad prompt with these commands do i have to enter them again when i turn on the laptop?
DISM /Online /Get-Drivers /all /format:table
dir c:\windows\system32\driverstore\FileRepository\*.inf /s /a
No. Not those commands. I posted the latest ones.
Ramesh i am faced with a forced update before i shutdown the laptop. I am afraid that the progress will be wiped. Should i continue with the update?
Here is also the latest command: drivers2.txt
You're already using the latest OS build. What's that forced update?
I think it's for the repairs, and the drivers that won't install
Please open Settings → Windows Update and check for any pending installations.
Here they both are, i already tried restarting a few hours ago and they were still there
Ok. The 26H2 repair version is pending installation.
Please click Update and Restart. It will likely fix the two inbox drivers. Let's see.
I wonder if the repair version will complete correctly. Usually, repair installation requires 30-40 GB of free space on the OS partition. 🤞
MY AUDIO IS BACK, THANK YOU SO KUCH RAMESH
Excellent. I'm glad it's sorted!
Although, i checked my device manager and i have 4 unknown devices that have yellow traingles next to them. coul you help me with these tomorrow? thank you ramesh i really appreciate the time and effort you put in to help me.

Sure. Tomorrow, post a screenshot of unknown devices.
Also, post the output of the following command:
pnputil /enum-devices /problem /ids
I'm going offline too.
Good day Ramesh, here is a screen shot of the unknow devices on my device manager
Hi @Mista Bucca Good morning!
Post the output of the following command:
pnputil /enum-devices /problem /ids
Hello Ramesh, here is the output drivers.txt
See if installing the chipset drivers for your model helps.
Hello Ramesh, i tried to chekc my amd install manager and it said my chipsets didnt need to be upgraded, and if i tried opening the exe file of the file you sent me its not opening/ its taking too long to launch
Ramesh pelsae help, the audio problem came back again while iw as updating my amd software, and i dont know what to do
The hardware ID USB\VID_0955&PID_9000 corresponds to the NVIDIA Virtual Audio Device (Wave Extensible) (WDM).
The hardware ID USB\VID_0956&PID_9001 corresponds to the NVIDIA Broadcast (or legacy NVIDIA RTX Voice) virtual audio device driver.
The hardware ID ROOT\AMDSAFD&FUN_01&REV_01 belongs to the AMD Streaming Audio Device, which is a virtual or internal audio component bundled with AMD graphics drivers (such as AMD Software: Adrenalin Edition)
Ramesh pelsae help, the audio problem came back again while iw as updating my amd software, and i dont know what to do
Which AMD software did you update? Chipset drivers?
Hello ramesh, i panicked too quickly, the audio is back now
After the update i had to restart, the unknow devices are still in the device manager
edit:
I have come to realize that my nvidia app has been un installed, i am currently in the process of installing it
Hello Ramesh, after updating my nvidia drivers the unknown devices have went down to only 3 left.
Please share your Farbar scan logs for analysis.
FRST64.exe to FRST64English.exe.Note: If Microsoft Edge or Chrome mislabels the Farbar Scanner executable as PUA/malware, choose to keep it by tapping … in the bottom bar, choosing Keep, and then choosing Keep anyway in the dialog that appears. See this screenshot. It's a safe tool used in most antimalware forums.
Ramesh, my virtual audio driver for nvidia broadcast is not available, i have already tried to update it.
here is the link to the frst.tx and addition.txt https://gofile.io/d/dHvRXiAQ
I'd suggest uninstalling the following product:
RAV Network Protection (HKLM\...\ReasonLabs-EPP) (Version: 7.7.12 - Reason Cybersecurity Inc.)
Uninstall it and restart Windows. Not sure if it removes those unknown devices, but the above product was most likely bundled with some other product and installed without the user's knowledge.
Do i just paste it into command prompt? should i also create a backup incase something bad happens?
Create a System Restore Point.
You can uninstall that app via Settings → Apps.
Once done, post fresh FRST logs.
Hello ramesh, here is the link https://gofile.io/d/yUBwslnS
Please run the fixlist below.
Fixlist.txt to the same folder as FRST64English.exe.NOTE: The fixlist.txt script was written specifically for this user and for use on that particular machine. It is not recommended to run it on another machine, and don't run the same fixlist.txt more than once.
Hello ramesh, here is the fixlog txt Fixlog.txt
The three unknown devices still present in Device Manager?
phantomtap is related to third-party VPN. What are the entries you see if you expand "Network adapters" in Device Manager?
If you delete all three Unknown devices and scan for hardware changes, do they reappear? Two of the three items may be virtual/software components.
If i delete them should i also restart after?
Delete the 1st item. If prompted to restart, restart. Else click scan for hardware changes.
Nothing showed up when i deleted it, should i delete the other two now?
Yes. Delete the 2nd one.
From the Action menu, click Scan for hardware changes.
Nothing aswell, do i proceed with the last one?
Yup. Please remove the 3rd one and restart Windows. Check the status again in Device Manager.
Ramesh something changed in the network adapters, i dont know if this is good or not
but the triangle marked drivers on the other devices tab are now gone, they didnt reutrn.
Great. The leftover virtual devices are gone.
To remove files/folders created by the Farbar scanner, rename FRST64.exe to Uninstall.exe and run it. The procedure requires a reboot.
You can delete the C:\DrvStore folder.
Backup C:\DrvStore2 to your external drive in case you need those drivers later (e.g., after a clean installation or something)
When after i do the renaming and uninstalling i restart my laptop and its all good now?
one more thing also do you know how i can resolve this problem ramesh?
Reinstalling NVIDIA Broadcast might help.
https://www.nvidia.com/en-us/geforce/broadcasting/broadcast-app/
This has kept on happening even after the reinstall. I dont know why its like that. Before i reinstalled it had the same problem, and it still has it after the reinstallation. Do you also know how i can increase my storage? it took a heavy blow from doing the tasks hehe
Maybe you can post that in the NVIDIA forums. Looks like other users reported the issue before.
Do you also know how i can increase my storage? it took a heavy blow from doing the tasks hehe
Run Disk Cleanup (cleanmgr.exe) as administator.
cleanmgr.exe and click OK.Restart Windows and check the available free space in the C drive.
Ramesh should i also delete the recovery backup that FRST made
Hello ramesh, i am in the process of cleaning up my cdrive, thank you so much for the time and help that you gave. I hope we'll get to talk again soon, see you around!
edit:
also i checked and windows has an update called
"Advanced Micro Devices, Inc. - Display - 31.0.12028.2" should i download it?
Yes, install that update.
From Command Prompt admin, please run these commands:
md C:\DrvStore
PnpUtil /export-driver * C:\DrvStore
DISM /online /get-drivers /format:table
Copy the output to a text file and upload it in your reply.
drivers.txtHello ramesh, here is the txt file
Hello ramesh I am having a hard time trying to figure out the steps, i have put the unzipped file in my cdrive and when i unzipped it gave me the file but also put the setup and everything in another file within that file. drivers.txt
Did you see the updated command I posted?
Yes, its currently running i will give you the txt version as soon as it finishes, thank you
Hello,
Welcome to the Microsoft Windows Community.
Good morning. This issue is easily resolved; simply download and reinstall the original drivers for your device from the Acer support website, simply unzip and run the file; once the installation is complete, restart your computer.:
I hope these guidelines help resolve the issue. If possible, please come back to share the outcome and rate the support you received. Your feedback may also help other community members who are experiencing a similar situation.
Hello! Thank you for your response. I did download the installer from acer themselves. The version you have given sadly doesnt work either and im still receiving the smae error codes. Thank you!
Hello,
What error message do you receive when trying to run the installer? Please follow these steps:
Hello! The error code I receive is 0x00000002, I decompressed the file on a folder and I've done the steps right. I tried doing a system restore and it stops at 16%
AI answer
Install the Windows 11 audio package matched to the laptop’s exact Acer serial number or SNID directly from Acer Support instead of retrying the failed driver installation in Settings.
AN515-416, which should be verified because a single incorrect digit can select the wrong driver package.Microsoft recommends obtaining the manufacturer’s Windows 11 driver when Windows Update does not provide a working version.^2^
The available documentation does not identify a model-specific cause for error 0x00000002, so avoid downloading a generic Realtek package from an unrelated driver website.
Clean out the incomplete audio-device installation, and then rerun the Acer package:
This is Microsoft’s documented recovery procedure for an incomplete or corrupted audio-driver installation.^3^
If both the Acer package and automatic reinstallation fail:
This generic Windows driver can restore basic sound, although Acer-specific features may be unavailable.^3^
If Sound, video and game controllers is missing entirely, or Acer Support does not recognize the serial number/SNID, verify the model identifier before installing anything further and contact Acer support with that identifier.
