Laptop Lenovo G450 badly manufactured

i got a Lenovo laptop g450 and was badly manufactured:
Notification
The Audio playback device HDA Intel (conexant analog) doesn’t work, falling playback to HDA Intel HDMI (HDMI Audio Output)
PHONON
Audio OUTPUT
It shows fade it (i would use that verb) “Internal Analog Stereo” (is not working)
Internal Audio Digital Stereo (it works)
Audio capture works…

Amarok plays the default file, but nothing else sounds, i got problems some problems installing repositories… Konqueror… and many other problems…
When i had win7, i got no privileges cause it didn’t recognize the root account i don’t remember the concept because it was in Spanish…mmmm
I installed both winvista and win7 and the audio output stop functioning…
thanks

Welcome to the openSUSE forum fengzhureloaded and sorry to hear of your problems. So I am not sure you have a hardware issue or not. Since you appear to be new, have you looked at our many resources yet on setting up multimedia? I always suggest a visit to here first and to do lots of reading:

New User How To/FAQ (read only)

We get almost all of our multimedia from Packman:

Packman Layout Explained

We only need to fetch the one file libdvdcss from another source that allows one to play a movie DVD. I suggest you read through this information, add in the Packman repository and do an update of your multimedia files and then see if your computer still has a problem.

Thank You,
