QUESTION: I need your help. My laptop speakers and my earphones, do not work. I have tried everything possible even complete new installation of OS, replacing daughter board, internal speakers... Nothing seems to fix the problem. The only time I get any sound from the speakers is when I'm trying to click on a wrong button (like F4, etc) during start up loading. The computer beeps and even makes sound when using Ghost restore CD.
One more thing... I do not know if this has anything to do with the problem, but I remember when I bought this laptop a long time ago, whenever I pressed the controls for adjusting the volume, it had shown bars on the screen. Now, I don't have anything showing on the screen at all, no matter what button I press. Do you know what application do I need to fix that? I have no clue and there doesn't seem to be anything available in the HP support page.
I updated all drivers, everything seems to be in order. I am in need of testing thoroughly my sound card and its diagnostics. Are there any tools for that? I suspect my sound card is being the culprit.
Laptop Model:
HP Pavilion dv4170us
SoundMax Sound card
Please, help. Thank you.
