text: can anyone give me the link to download multimedia audio controller software? i m not getting sound from my pc.speakers are ok.i dont have reinstallation cd of my system thanks assuming you have an onboard soundcard, visit the manufacturer  of your motherboards support forum. you should find the make and model of your motherboard printed on your err, motherboard, otherwise check your invoice.  you should also be able to see at least the model on the post screen (the screen you see when you start the computer). it's ussually top left about a quater down the screen or right at the bottem. you can press pause and write down the information. when you are done press enter and carry on. if you have a branded machine like hp or dell then you might need to press a certain key combination to bypass the oem logo.   anyway you can contact me with the info and i'll see what i can do or yahoo the information.  if you have brand name machine you should find the model printed on the side or botttem of the case/laptop in which case you can visit the site of the manufacturer.  hp/compaq http://www.hp.com dell http://www.dell.com asus http://www.asus.com gigabyte http://www.giga-byte.com  there are many otherbrands but i ussually only work with the above and generic pc's.  if you can open the case you might be able to decipher what controller your pc is using by reading the information off the soundchip, but you would need to know what to look for.  if you don't have an onboard card you can take out the soundcard and check what make and model it is and take it from there.   knowing you have a celeron doesn't tell us what audio controller you are using.
