This is not Open Suse specific since I’ve never gotten the sound to work properly (no output on lower frequences) with any distribution on this hardware, but I hope maybe someone here can help me in the right direction to get this sorted. I mailed the alsa dev list about a year ago but nothing happened… The sound works correctly under windows, of course.
As a** work around**, you could try installing ‘pavucontrol’ (from openSUSE OSS repos) and also 'pulseaudio-equalizer as packaged by packman packagers and then run ‘pulseaudio-equalizer’, followed (if necessary) by a reboot to restart pulse audio. Then start ‘pavucontrol’ and ‘pulseaudio-equalizer’ and play a multimedia application and attempt to tune its sound output with both pavucontrol and pulseaudio-equalizer.
which version of what? i’m using opensuse 12.3 64bit, all the details are in the link i posted. it’s a clean install.
thanks for the tip, I fiddled with the pulse equalizer but it can’t do much since there really are no output on lower frequencies. I think the driver is really not communicating with this device correctly, the NP8130 comes with two speakers and a subwoofer on the bottom. The subwoofer is dead silent AFAICT.
