Installation Problems

Hello,
thanks for the Zoom-driver! but it doesn't install on my Ubuntu 22.04.1 LTS.
As the way you described to install failed, (with no response)
I changed to /usr/src/snd-usb-zoom-0.0.1 and called "make" and got the following informations

sudo make
make -C /lib/modules/uname -r/build M= modules
make[1]: Entering directory '/usr/src/linux-headers-5.15.0-58-generic'

Could you help with this ?
Thanks in advance
