I've read the ASUS P5SD2-X english manual.  It describes about the
rear audio panel jacks:

 Audio 2, 4, or 6-channel configulation
 -------------------------------------------------------------------------
 Port		Headset		4-channel		6-channel
 		2-channel
 -------------------------------------------------------------------------
 Light Bule	Line In		Line In	[1]		Line in [1]
 Lime		Line Out	Front Speaker Out	Front Speaker Out
 Pink		Mic In		Mic In			Mic In [2]
 -------------------------------------------------------------------------
 (P5SD2-X English Manual E2026 (E2026_P5SD2-X.pdf), p.35)

And there are the manuals those are written in chinese.  I saw those
manuals today, and they have the same table.  I'm not familiar with
chinese, but I just understand that [1]s and [2] are "output".

AD1986A can share line inputs pins and surround outputs pins, and
center/lfe outputs pins and microphone input pins.

So perhaps [1]s are "Surround Out", and [2] is "Center/Subwoofer Out".

I've write a new patch attached below.  Try it.  Note that before
apply this patch, you have to restore the patched files.

Will you show me the output of "dmesg | grep pcm" and
"pciconf -lv | grep pcm" ?
