Sony SVS13a1s9e - Sound issue

[ranjit8083]

I have a a couple of these motherboards (Sony vaio SVS13A1S9ES) where there is no sound device detected. I've tried reinstalling the OS etc, but looks like a hardware issue with the sound on the motherboard, The sound device does not get detected within any Operating System.

I also have another one of these that is completely dead, not sure if anyone can take a look at these.

Thanks
