windows 7 AUDIO no work

Solution
Try re-installing the sound driver from your laptop or PC maker's website if it's a factory made PC.

For custom-built PC, download from motherboard manufacturer's website.

If it's an add-on PCI sound card, download from that card manufacturer's website.

That's all very basic stuff that any PC user should know, it's not rocket science.
