Many times the problem can be fixed by simply downloading the latest updated drivers for your audio card
. Audio driver updates can be found easily on the Driver Helper's website. You can find your audio card's drivers online by searching for the model name/number with the word "drivers" at the end of the search. For example, if your audio card model name/number is "audiocard #1234," then you would simply do a web search for "audiocard #1234 drivers."
