Very Low Microphone and Headset ( 3.5mm Jack) Volume Problem on ROG STRIX B760-F Motherboard

[smyasin]

Hi,

Recently, I, along with several other users, have encountered an issue with the ROG STRIX B760-F motherboard.

The problem is related to low microphone sensitivity and volume when connecting standard microphones or headsets (via 3.5mm audio/mic jack) to the motherboard. Despite installing all drivers properly and ensuring they are up-to-date, the microphone’s sensitivity and sound remain significantly low.

Here are the details of the issue and our troubleshooting efforts:

1. Operating System Tests:

   • The issue has been tested thoroughly on both Windows 10 and Windows 11 (Pro and Home editions).
   • We have tested the problem with no drivers installed, the latest drivers, and even older drivers available on the motherboard’s website. Unfortunately, the issue persists.
   • The Armoury Crate software has also been installed and tested, but it did not resolve the issue.

2. Hardware Tests:

   • Several microphones and headsets have been tested on three different ROG STRIX B760-F motherboards, including models like the ROG Cetra Core II.
   • The problem remains consistent, confirming that the issue is not with the microphones or headsets themselves.

3. BIOS and Firmware Updates:

   • All BIOS and firmware versions available on the motherboard’s website have been updated to the latest versions and reset to default settings.
   • Despite these updates, the issue has not been resolved.

4. Observation:

   • This problem tends to occur after reinstalling or switching the operating system (Windows) more than twice.
   • All tested microphones and headsets work perfectly on other devices, confirming they are not faulty.

Additional Notes:

• The microphones and headsets have been checked in Windows Control Panel, with the volume set to 100% and the boost set to +30dB. Despite this, the output volume remains very low.
• The microphones and headsets have been tested on both the rear and front panel audio ports of the case and motherboard, but the issue persists.
