Is anyone using Atmega162 Au (tqfp44) to make x0xb0x?

Hello everyone,
I'm making my x0xb0x. Because there is no Atmega162 16PU temporarily, I connect an Atmega162 16AU(TQFP44) with an adapter board and flying wire. After flashing the firmware, it seems that it works (the LED, encoder and keys look good), but there is no sound. I detected the pin 7 of ic11. No matter which key I press, it always remains at about 0.7V, So I tried to modify the fuse, l: FF, H: DC, e: FF, so that the pin 7 of ic11 becomes 4.08v, which still remains unchanged. Does anyone try to use Atmega162 16au? What should the fuse be set to?
