I have a problem on my laptop, Dell Inspiron 1420 (since 2007), after installed Windows 7.
That is sound problem. It doesn't any make a sound but earphone or headphone works.
So I tried to solve this problem, searched the all of the Internet, then I found the solution.
Download and install it.
R147073.EXE(Try to refer to this site http://en.kioskea.net/forum/affich-267928-lost-the-sound-on-dell-inspiron-1420)
So anyone who has this problem then try this.
Korean Ver
혹시 저처럼 델 inspiron 1420 쓰면서 윈도우 7 설치 후 스피커가 안나온 문제가 있으시면 위링크나 파일을 설치해보세요.
그리고 저의 짧은 영어는.... 예쁘게 봐주세요^^;;
