Summary: No surround sound on ICH5 (AC'97 AD1980)
Description:
I cannot get my AC'97 device (AD1980) to produce any sound other than
stereo output. I have tried various settings on alsamixer and I used
various speaker-test forms to validate settings. When I use:

speaker-test -Dplug:surround40 -c4

then I hear just Front-Left and Front-Right. There is total silence on the
rear channels. I plugged the rear speakers plug into the 2nd sound output
jack.

Some hints would be appreciated. I have been searching around the internet
and have found other issues regarding the AD1980, but not this one. I do
realize it may be my setup that's wrong, but the chance is getting quite
small by now.

I'm not sure whether I set or unset 'PNP OS'. I'll have a look at the BIOS
settings when I come home.

I do not even have a 'PNP OS' setting. So what's the next step? Do I need
to provide any additional feedback? Note that I installed Windows XP (SP2)
this week, but I could not see how to enable surround sound there. I could
indicate I have Quadrofonic speakers, but I'm not sure whether that should
work.
