Audio stopped working Thinkpad390

2020-10-13, 9:08 AM

Hi all,

I hope you can help, I already tried everything (at least it feels like it).

My audio stopped working out of a sudden. Microphone and Speaker. I deinstalled them, reinstalled them, downloaded new drivers, used the problem solving tools and nothing works.

When looking at the realtek devices in the system it says everything works fine. When you do the problem solving analysis it says realtek is not even there and the result is that the problem could not be solved as the audiodevices do not react. 

error codes are: 0xA00F429C

I also get 0x0000007E Module not found...not sure what that is or whether it is linked.

Thank you,

Franzi

Hello Franzi1985

 

Welcome to the Community Forums

 

Windows updates have a way of messing with hardware drivers, as they sometimes tend to not be compatible with the hardware made by the laptop manufacturers, be it Dell, Asus, Lenovo etc etc.

What usually helps is denying Windows Updates from affecting hardware drivers completely. You can do this by performing the step below:

 

Disable Automatic Hardware drivers update

- Right click the Windows Icon, select the "Search" Function.

- Type "Control Panel" and select "Small icons" or "Large Icons" in the "View By" top right.

- Click the "System Icon"

- Navigate to "Advanced System Settings" -> "Hardware"

- Click "Device Installation Settings" and Select "No"

**This will prevent Windows from interfering with your hardware drivers in future updates, but keep crucial security updates rolling.

 

Press the Windows Key + X, or right click the Windows icon in the bottom left. Select Device Manager from the list.

 

Expand the following areas:  

- Audio input and output   (Realtek Audio or similar)

- Sound, video and game controllers  (Realtek Audio or similar)

- Software components (Realtek Audio Effects Component and Universal Service if listed)

- System devices (Intel Smart Sound and/or High Definition Audio Controller)

**Note: Start from top to bottom

 

Update them by choosing from the driver lists on your computer, make sure to choose the most recent Audio related drivers you can find:  

 

- Right Click the devices

- Select Update Driver

- Browse my computer for drivers

- Let me pick from a list of available drivers on my computer

- Select the most recent Audio related driver from the list for every device then Click Next

- Close confirmation dialog.

 

Resetting to the default setting in BIOS can help fix "Sound device not found/detected"

 

BIOS reset

- Press the power button to completely shut down the unit.

- Press the F1 repeatedly on startup to enter BIOS.

- Navigate to the "Restart" tab

- Press "Load Default Settings"

- Save & Exit changes or F10.

 

For Microphone issues, I have a post here.

Also check Windows own mic solutions here

In regards to the the 0x0000007E Module not found, that could be the Lenovo Power Manager having problems reinstalling. Check this forum post for a possible fix.

 

Hope this helps

 

Regards

 

Voithos
