If you use a Stereo profile in PulseAudio, then it will only show you
the stereo channels.
Use pavucontrol and on the Configuration tab you should have a 5.1
profile. Simply select this and you should have the full five channels
exposed via PA.
If things don't work for you then there is a good chance that alsa
driver issues (via what they expose in a uniform and consistent way via
the mixer interface) or in PA itself may be at fault. As both your alsa
drivers and PA version is really old, I think you should probably try
the latest versions before drawing any conclusions.
