Dell N7110 no audio device detected at all

[mmsoft]

Hi,
I was having a problem with graphics chip and did reflow. Now graphics works fine but there is no audio device detected at all. No sound device in Device Manager.
Laptop is Dell Inspiron 17R N7110.
Any suggestion ?

Thank's

were the audio problem and the graphics problem started at the same time?

At first was graphics problem - when installing AMD driver laptop freezes.
Sound was fine.
Done reflow of the graphic chip and graphic problem was solved - driver installs and working nice but sound has gone - no sound device at all.
I begin to think that this was some coincidence - sound chip is at the oposite end on the motherboard from graphics chip and looking at the schematics there is no direct connection between VGA and Sound - sound is connected to chipset.

is there any visible damage to the Audio chip? how much heat was applied to the Audio chip during the reflow process?

No damage to sound chip - I was heating graphics chip and it is far from sound chip. Didn't touch the sound chip
