Oh sorry, I didnt understood it. Here they are attached, But thosse
are the ones I
extracted from chromos[0] images as pointed out on Jasons github page [1]

I see I have plenty of them in /lib/firmware/ so I am not sure which
ones you want.
Here is the list of the ones I have:

lrwxrwxrwx. 1 root root     23 23 gen 10.28
/lib/firmware/intel/dsp_fw_kbl.bin.xz -> dsp_fw_kbl_v3402.bin.xz
-rw-r--r--. 1 root root 131932 23 gen 10.28
/lib/firmware/intel/dsp_fw_kbl_v1037.bin.xz
-rw-r--r--. 1 root root 132308 23 gen 10.28
/lib/firmware/intel/dsp_fw_kbl_v2042.bin.xz
-rw-r--r--. 1 root root 133888 23 gen 10.28
/lib/firmware/intel/dsp_fw_kbl_v2630.bin.xz
-rw-r--r--. 1 root root 133832 23 gen 10.28
/lib/firmware/intel/dsp_fw_kbl_v3266.bin.xz
-rw-r--r--. 1 root root 134512 23 gen 10.28
/lib/firmware/intel/dsp_fw_kbl_v3402.bin.xz
-rw-r--r--. 1 root root 134060 23 gen 10.28
/lib/firmware/intel/dsp_fw_kbl_v3420.bin.xz
-rw-r--r--. 1 root root 131020 23 gen 10.28
/lib/firmware/intel/dsp_fw_kbl_v701.bin.xz

If you need all of them let me know.
