I recently re-formatted my PC and now my audio isn't working. I used to have a CD with the driver for it and corrected it when I reformatted last time, but i've lost this CD now and I can't remember the brand.

Is there anyway for me to recover this firmware or check the brand of my sound card to download some firmware as I can't see anything visible to indicate what it is?

I've updated the drivers for my motherboard and graphics card but no luck.

Any help would be appreciated. Thanks
