I have a relatively cheap SoundBlaster card, lspci sees it as
"Creative Labs SB Audigy LS". It has 4 jacks on the back panel,
colored blue, green, black, and orange. There are mysterious icons
next to the jacks. In simple words, what is the function of each one?
By fumbling around, I have found that the green one plays the system
test sound into a set of unpowered speakers.
This is specified in the PC99 System Design Guide, promulgated by Intel
and Microsoft years ago. It's now being sold in hard copy, but is still
available as a PDF here:

This used to be widely available on the Internet and apparently has been
taken down from most websites, probably to support book sales.
The color coding is described in section 3.18.3, and some of the icons
appear in Appendix A.
