If I connect a USB flash drive, the internal microphone doesn't work. I don't understand what the problem is. If I don't have a USB device connected, the internal microphone works perfectly, but if I connect a USB device, the internal microphone stops working correctly.

What is your USB flash drive format? Is it FAT32?
If possible, please try to use other USB flash drive to test how it goes.
