Hi. I have no sound coming out of my laptop. I have a HP Pavilion N5415
Laptop with Windows XP SP2. I don't know how this happened exactly, I just
remember that one day I turned it on and there was no sound. I went to the
device manager and found out that the Multimedia Audio Controller had a
yellow question mark beside it. I have tried many things since then: After
searching on the HP webpage and others, and after using hardware detecting
software I found out that I had an ESS allegro sound card, so I downloaded
the driver from their web page. While installing, I got a prompt that said on
the header "SEVERE", containing a red "X" followed by the phrase "Audio
Installaion False". After this the installation is finalized and I am asked
to restart the computer as if nothing happenned. I downloaded the driver
from the HP web page and got the same answer. Then I tried installing the
driver manually, in which at some point I get a prompt telling me that it's
risky to install the driver, since windows can not recognize it. Once the
"false" installation is complete, all the features of the sound card are
active, like the volume controlled by the function keys. For the computer,
everything seems to be working perfectly, except that there is no sound at
all, and when I play a video file on Windows Media Player, the video pauses
itself every 4 or 5 seconds (I think meaning that there is a conflict with
the driver). I also noticed that when starting the computer, I had always
heard a sound (like when one hits a microphone) during the XP startup logo,
and that's gone, meaning that the sound card doesn't load at startup. I would
greatly appreciate any help on this matter. Thanks.
