ask your vendor to provide you with something that isn't 8.5 years old.

even then, you'll still be on your own, sorry.

i am new to openwrt , i have mt7628DAN EVB board. can you please suggest me appropriate openwrt version which provide wm8960 codec support

Didn't google much, but it seems at least Linux kernel 5.10 and onward have the support.

5.10 is openwrt version 22.03, next release (current snapshot) should be based on 5.15.

These devices use the same SOC, I'd try to use any of those as the point of entry.
