As the title says, i managed to fix this issue on a t4pro, it should work on other mini PCs using the KT_USB_AUDIO Device.
After days of trying a lot of fixes from internet, I finally fixed the audio issue:
1. Right click on start, select Device Manager
2. Select Universal Serial Bus Controllers
3. Uninstall ALL USB Composite Devices (all, you will lose access to the mouse and keyboard. If it doesn't work the first time, retry until you uninstall all USB Composite devices
4. As you have no keyboard or mouse, long press the power button to power off, then press to turn on the mini PC.
5. Audio is restored on 3.5mm jack
I tried a myriad of drivers and hacks, turns out this KT_USB_AUDIO is driverless, or at least it doesn't need an audio driver, the only driver controlling this device is the USB Driver. Hope it fixes many no audio issues i read in this forum, I am totally amazed how come even the vendors don't know how to fix this issue. To be honest i was about to throw this mini PC to the trash can or buy an external sound card (Which fixes this issue too, but you will lose a USB port). Suggestion: Do not reinstall Windows, do not update, as my audio disappeared when I reinstalled Windows.
