I think this has to do with the proprietary audio software that your laptop uses. Did you clone the recovery partition as well? can you load the recovery and see if it can repair it/install its own drivers
if all else fails, reinstall windows. and install the driver
but not the software. if it still doesn't work, install the proprietary software. if that doesn't work, contact Lenovo and get a install disc from them.
I guess I am all out of advice otherwise. wish I could help more
