Windows 7: HP dc7700 internal speaker silent after installing Radeon HD6670

HP dc7700 internal speaker silent after installing Radeon HD6670

After i've installed new graphic card and drivers to my refurbished HPdc7700, all my previous sound devices and settings were completely erased and automatically replaced with AMD Digital Audio (HDMI). PC is connected to speakerless monitor through DVI connector, so i really don't need this feature. I unistalled all Sapphire software and drivers, reinstalled Realtek drivers, but nothing helped, so i've found that onboard soundcard was disabled in BIOS!
I have removed all traces of AMD Digital Audio and reestablished Realtek (tried two recent drivers). Now everything seems right in place, signal is present in front and back output, but internal speaker is muted. I've tried everything logically possible in Realtek and Sound settings.

Device Speakers (Realtek HD Audio) is now set on front panel output. How can i change it to internal speaker?


tnx

Welcome to Seven forums kkoxic.
You have an internal speaker? I have one which gives me beep codes at startup.

I have internal speaker that worked (played music) well, until i installed that damn graphic card, which completely erased all my sound settings, including devices. Now i managed onboard card to work normal for front and back output (3,5 jack). I don't know how to make internal speaker to play( music, movies, games) again, after i eject external audio devices.

You shouldn't be in the registry trying to install drivers. If you have a System Restore go back to before you installed the AMD driver and choose custom install and leave the audio driver out, if this is possible.
