I have a Dell Inspiron laptop and recently the sound will work one minute and then not the next. When it does work, it sounds normal and it doesn't fade out or anything like that. I turn on the computer and it works fine, then when I close the laptop for awhile and come back, nothing will come out of the speakers, but it works with headphones. Also, sometimes it stops working after I have been using Adobe Illustrator, or other big programs. Once I restart it always works again, but restarting constantly is REALLY annoying. Any suggestions?
