Default Why is side left and subwoofer swapped for 7.1 in windows 7 ?BUG BUG !!!

And all connections connected to the proper inputs on the denon receiver 1909.

I am not sure about the subwoofer/side left connections.

There are two configurations possibly.

1: Subwoofer sound goes to SIDE LEFT.

2: Swapping them: No sound.

The subwoofer is missing though, perhaps the denon receiver detects this ?

But it's more likely a weird situation in windows 7.

PDF 83 of 93.

7.1 setup, two of the Lineout connectors have a total of *four* contacts.
This requires adapter cables when connected to "ordinary" equipment.

The adapter cable has Gray and Orange on one end, and *three* stereo
females on the other end of the cable assembly.

LineOut1 Green Tip Front Left === Ordinary 1/8" cabling
Ring Front Right
Sleeve Ground

Lineout2 Gray T Rear Left === Special 1/8" TRRS
R Rear Right
R Ground
S Side Right

Lineout3 Orange T Center === Special 1/8" TRRS
R Subwoofer
R Ground
S Side left

No, they don't give a part number.

If you're preparing home-brew cabling using bits and
pieces, you at least need to buy yourself a couple
TRRS adapters. You need the male with the four contact
surfaces on it. The rest of the materials will be easier
to locate.

If you go to stereo or computer stores, they're not going to
have the exact cable. It's a cable you cannot afford to lose,
as there are so few four-contact plugs around. (Yes, you can
get them from China, but not so easy to get in your own
country at a store.)

The part with the screws on the end, only accepts a
small gauge of wire. I have an adapter with that
screw type on one end, and it isn't that nice to work
with. Having screw terminations means no soldering
is required, but the wires will not be held all that
securely. If you tighten the screw too much, you
can weaken or snap the stripped wire end.

This is the way I would prefer to make the adapters, with
a "1/8th inch soldertail TRRS". When soldering these, you cannot
apply heat for very long (various plastic bits will melt
and deform and stuff will be shorted electrically). I might
reflow some small gauge solid wire to these or something.
It takes practice to not damage these. I made a real mess
of one once, on my first try :-)

You can do the job entirely without solder, using screws and
wires. But it's not really all that much fun. Just finding
solid wire is a challenge. The electronics store doesn't
actually have "good" nickel plated wire any more. That disappeared
about 30 years ago. Only ****ty copper wire with no plated
conductors for easy usage. Stranded wire won't work well
underneath those screws. You'd have to "tin" the wires
to make a surface to screw onto.

I'm not sure the "mis-connections" possible with those
jacks, account for your channel mixup. But it's a common
complaint with Creative stuff. You *have* to be careful!!!

As soon as you say "Creative", I think back to those
stinking cables and what a nuisance they are.
