Noise from my SAT Radio hook up
Here is my problem, I have installed my carpc and it works great. I have a 120 gig external hard drive that runs off of usb power. In this hd I have all my mp3's, videos, and pics. I am using RR with digitalfx 3.0. Everything works like it suppose to without any kind of problems.
Now, I hooked up my sirius sat radio adapter (see link) http://www.rush2112.net/mkportal/mod...products_id=35
the way I have this setup is, positive connected to the IGN of the power supply, negitive to a direct ground. USB from the adapter to the pc and the audio output from the adapter to the MIC IN on the sound card.
When I turn the engine on, I have a loud hum that gets louder as the engine goes faster. Here is the catcher, when I unplug the AUDIO OUTPUT from the sat adapter the hum goes completely away!
I can even listen to my MP3's and or video's at any volume driving at any speed and I have no Hum!
My question is, should I think about grounding the sound card it's self? Or is there another way to get rid of this hum while using my Sirius Sat Radio adapter?
Oh and by the way the sat radio works perfect both with the engine on or off! Just has this hum when it's on.
I am using creative labs Audigy2z see link: http://images.google.com/imgres?imgu...%3Den%26sa%3DN So it's not the intergrated sound card.
Please help if you can.
