On my Dell XPS M1330, I was having, Vista as the operating system. Till when I was using Vista on it the speakers on the laptop were running fine, there was no problem with it. Recently, I switched to Windows 7. Now the speakers refuse to work. I am facing many problems with the laptops now. When I go for the sound test in the Control Panel, the tests return me saying Failed to play test tone. Also to add, I even do not receive any sound in the headphone as well. Can you all tell me what should I do? Is Windows 7 causing this problem? I do not think so. Please Help.
