I have an AC'97 based onboard sound card in my system (snd_intel8x0 driver). I'm using it in 6ch mode to drive two front speakers, two rear speakers and a subwoofer and center channel. Using speaker-test with the surround51 plug (or any other alsa program with that plug) to send audio to channel 5 (center in alsamixer) produces an attenuated signal on channel 2 (right front in alsamixer) and likewise, sending audio to channel 6 (lfe in alsamixer) produces an attenuated signal on channel 1 (left front in alsamixer).
This looks like a flaw in your hardware.
What codec are you using? (see /proc/asound/cards)
