One of the most popular sound boards I've seen used is the audigy.
new here, usually on fiatforum, but there ICE section just doesnt have the expertise.
when i plug amplifier in via the 3.5mm jack on the motherboard, it generates TERRIBLE noise.....even with ground loop isolator (dont like using them anyway, they just "mask" the problem)
so i bought a creative x-fi usb audio, this worked with a dramatic improvement reguaring noise. but it has lots of problems with windows and reusming form hibernate.
anyone have any gems of wisdom to help me out here??
could youy elaborate a lil?
no i havnt, when i tried this before, the motherboard sparked, smoked and died....whats the safest way to do it? as this sounds like the most logical step....
Also, try flipping the ground loop isolator in the other direction.
How is your car's audio setup? Do you use a head unit? Do you have any amps?
How is the computer powered? Are you using a power inverter? A dc-dc power supply?
Is there an inverter in your car at all?

i dont think flipping the ground loop isolator will make a difference, due to its design, (its essentially 2 coils, side by side, so what ever way it is, it will be the same, unless its broken) also mine only connect one way.
i go from car pc straight via 3.5mm jack, to delta box, then to 2 amps with 3 channels (front, rear, sub) thats how it is at the moment. no headunit.
power comes from M1-atx/M2-atx (not sure, it came with a job lot of stuff i bought as an unfinished project, and is the of the only surviving original bits) supply, no inverters.
last time when i tried to ground it (dont laugh) i wound a wire round one of the screws holding the motherboard down, so it was making contact with the little metal ring round the screw holes, then connected this to chassis.
Then just connect the other end of the wire to a solid ground point on the chassis, even better would be the same point the power supply uses for ground.
Just make sure to do everything with the computer off and the power supply disconnected from the battery.
i did it with it on, because i was probing to see if it made better/worse, like at the opticians with lenses.....
possibly not the best idea...
What motherboard are you using? is it with VIA chipset?
