http://askubuntu.com – I have already installed GNOME ALSA MIXER on Ubuntu. I did set the all the parameters correctly. In Hardware settings, in the "choose a device to configure" section, it appeared as "Built in Audio - 1 Output / 1 input - Analog surround 5.1 output + analog stereo input" because I've selected that "Analog surround 5.1 output + analog stereo input" as the profile. So the setting may be OK I think. But it only activates 3 channels in my audio system. Front Left, Right and the Sub woofer. Other channels don't work well. Please give me simple and clear solution for to get this right. Guys pleas (HowTos)
