khadas graphics microphone problem

I purchased khadas graphics via the official website with an early bird discount (-$100). Recently I received the product, however, after using it for a while, I now face a challenge problem with speakers.

In the beginning, it works smoothly, suddenly, the microphone does not work at all. The speakers are still working correctly, but the mic cannot receive any voices. Although I plug an earphone into the 3.5mm, the speakers are also OK but the microphone still cannot work.

I tried to uninstall the device in the Windows device manager and reinstall it, however, the problem is still not solved.

How can I make it work?

Environment: windows 11 home 23H2, version 22631.3880, with khadas mind i7 version (32GB+1TB)

Hello @wty7151

麻烦试下如下操作:

1、Mind + Graphics,先关机Mind,完成关机后拔走Graphcis电源,再重新上电开机
2、打开系统设置→声音→查看输入设备呈现为Khadas Mind Graphics Speaker(表示为MIC输出)还是呈现Khadas Mind Graphics Microphone(表示为耳机麦克风输出) - 并截图贴出来
3、打开系统设置→声音→检查输入音量是否开至30%以上 - 并截图贴出来
4、打开设备管理器→音频输入和输出驱动→检查Microphone驱动是否存在 - 并截图贴出来
