Windows 10: I'm not having any luck with the Input device installed on my laptop

Hi! I've been researching the fixes for this issue, and nothing is working for me. The sound is working fine it's just the microphone. It used to work fine but it's been gone for a few months now. I've been using my husband's office for my remote meetings. I really would like to get this fixed. If you have some time to help, I'd appreciate it. thank you, CTL

:)

Does your system boot in EFI at the moment ? f the error "the requested system device cannot be found" occurs when you try to perform Bootrec operations using a USB installation media, it may not find the correct system partition, which causes bootrec /rebuildbcd: The requested system device cannot be found Windows 10 issue. You may try this method to set the correct partition. Step 1. Boot from a UEFI Windows 10 installation (CD/DVD/USB) disk, and in Advanced options page, choose Command Prompt. Step 2.

Laptop driver/reformat question

This is excellent advice. Writing down the list of installed devices prior to re-formatting will save you a lot of heartache. With that list, you won't have to try to figure out exactly which wireless card or web cam driver you need since there will likely be several to choose from.

 

no output device is installed ... so sound from my laptop

Hi Vijay,

Thank you for posting your query in Microsoft Community. appreciate you interest in Windows 10.

I suggest you to check if the audio drivers are installed by checking in Device Manager by following the steps below:

1. Press 'Windows key + R' and type 'devmgmt.msc' (without quotes) and press enter.

2. Expand 'Audio inputs and outputs' and check if there are any drivers listed.

If there are no drivers listed, then install the latest drivers available or from the drivers CD which was obtained when you had Windows 7.

Hope the information is helpful. Feel free to
