Hi BlairWB
Welcome to Microsoft Community.
Based on your description, I understand that you can't use the microphone with either Bluetooth headphones or plug-in headphones, and I know exactly how you feel!
You have tried very many solutions and commend you on your problem solving skills and thinking!
(1) May I ask that have you updated Windows recently?
(2) May I ask that that you encounter this problem all of a sudden? Did you encounter this problem all of a sudden, or under what circumstances? How long has the problem been occurring?
I personally have encountered similar problems when using Bluetooth headsets, and I will provide you with some solutions that you have not tried before in my personal situation, and hopefully, I can solve your problem successfully. However, the first reply may not be able to solve your problem successfully, please understand and provide more information in your reply (pictures would be better!) , thank you very much!
Option 1: Since plug-in headphones also experience this problem, it makes me a bit strange. It's a bit strange that plug-in headphones are also experiencing this problem, because normally, plug-in headphones work fine when Bluetooth headphones are experiencing this problem.
Try using the Realtek Control Audio app to check and make the relevant settings.
Because Realtek Control Audio is able to detect Bluetooth connection and plug-in connection type of headphones and manually make the relevant settings. For example, microphone, audio band, etc.
Realtek Control Audio can be downloaded and installed from the Realtek website or Microsoft Store.
Option 2: Try to reset the network settings.
You must be wondering why it involves network related situations.
This is due to the fact that network settings and Bluetooth settings can interact with each other in some cases, and you can minimize the conflict between network settings and Bluetooth settings by resetting the network to clear any possible configuration errors or conflicts.
Click “Windows Logo Key” to open the search bar -> Enter “cmd” in the search bar and open it with administrator privileges -> Please enter the following commands
ipconfig /release
ipconfig /renew
ipconfig /flushdns
ipconfig /registerdns
netsh int ip reset
netsh winsock reset
netsh winhttp reset proxy
Option 1 and Option 2 I have personally performed and solved the problem I was experiencing.
Option 3: Try to pass the type of sound card driver, for example in the following case:
(1) The sound card driver provided by the motherboard manufacturer
(2) Sound card branded drivers
(3) Some headset devices require additional driver support, e.g. Razer, Logitech, etc. Since I haven't used a device similar to yours, you can use it as a reference.
Please note: The newer the driver, the better it is, as we normally think that the newer the driver, the more devices it supports and the better the compatibility. However, in some cases, a more stable driver may be more suitable for our environment. You can try some different versions of older ones.
Option 4: Your current version seems to be 22621.4037, you can try updating to 22631.4112 or downgrading to 22621.3958 to see if there is a difference in the system version. Because considering you have a similar problem with your plug-in headset, I think it's possible that some patch conflict could be the cause.
Option 5: Can you please try to safely boot your computer to see if the problem still persists.
For safe boot you can refer to: Windows startup settings - Microsoft Support
Since the system only uses a limited set of drivers and files in Safe Mode, it can effectively avoid third-party applications, driver conflicts that cause problems.
If the problem disappears in Safe Mode, please check the recently installed, updated and frequently used third-party applications, drivers, etc. and uninstall them.
I sincerely hope that the above solution will solve your problem. Please feel free to contact me if you have any problems or still can't solve them. (Photos related to the question would be great!) .
I look forward to hearing back from you.
