LOL -- you make a funny *** smokin' joke about our 3rd/4th/5th world

Likely from it's onboard chip occupying the same address registers
that a PCI soundcard would use

This is doubtful. The PCI standards were explicitly designed so that
PCI devices wouldn't step on each other's I/O port ranges, and would be
able to share ISA IRQs.

Yeah, yeah, but *which* standards the Manu follows is up to them (and
their willingness to collaborate with the Evil Redmond Behemoth).
*Plug-n-Pray* is supposed to work correctly, as is the enumeration of
PCI devices, but doesn't always do so.

good start for t-shooting, especially on 'cheaper' mobos.

The best way to troubleshoot a cheap-ass x86 motherboard is to use a
12-gauge.

Or a 16lb. Sledgehammer...

mplayer doesn't use that [4-wire] cable at all for playing mp3s or
audio data embedded in ASF/AVI/MOV/whatever files.

Are you sure about that ?
[ relevant info that was previously snipped ]
ISTR; Mplayer (which I have not even used/installed yet) started out as
one of Linux's 1st DVD player -- aka 'Optical drives' -- I could be
mistaken about that... and the OP hasn't yet mentioned if the "video"
is from a DVD in the optical drive or what. As for MP3's?, I didn't
know mplayer plays mp3s, but I guess I'd say now, well why wouldn't it.


Yes. The 4-wire cable is there so that the CD-R* device can read CDDA,
do the D->A right on the drive, and push the A sound directly to the
soundcard. It is not common for a CD-R* device to be able to decode mp3
data in that way. *Possible*, sure, but there's no guarantee, and it'd
surprise me if there's a standard interface for those functions.

I know what that Analog 4pin and Digital 2pin output wires are for and
what they do and how optical drives work ...I never even remotely
suggested that Optical Drives (meant for PC use) can "decode" MP3
files. There _are_ ofcourse *combo* units (STBs as well as Car-Audio
units, External devices) that have these capabilities, but we're not
talking about them AFAIK.

The OP sated that he *got* _Video_ playback but no _Audio_ from that
same source stream -- if that stream is/was a DVD-ROM (or similar) then
it's possible only the Soundcard settings/hookups are at fault (and/or
the BIOS settings too) - meaning the Optical device is working
properly, but the Audio output hookups may be wrong.
YMMV ofcourse...
