Hey bhopal,

Here's a video on some things you can try.

The Code 43 normally means it's a Hardware problem.

What did you mean by " disable and re-enable the device"?
Did you get into the BIO's CMO's Settings and turn off and on the AUDIO chipset?

Or if you can....
Try a stand alone copy of linux, and see if the audio works with that.
If it does, then there is an issue with the latest set of audio drivers that you have.
You might want to try an older set of audio drivers to see if that it will work.

If you still have no audio.
Check your warranty, and contact Lenovo about repair or replacement.
