    problems with aux sound

    Hello guys, so i have this for you and i really hope you can help me cause otherwise my installation would be pretty useless
    So, i completed my installation of my pentium 4 pc and i have this problem.
    I am trying to listen from my radio-cd the pc's sound via an aux connection
    -the same radio works with aux with my netbook
    -the same pc works with normal pc speakers...
    -Also the sound car is reaaaaally old (pantium 4 age, on board...)
    So i have connected them with a 5m aux extantion, and then a 1m male-male aux calbe... the same cable except that its long, it also passes near the power supply cables of the inverter and the pc powe supply (near 750w total) and its not anything spacial to be shielded or something.... anyone has something to propuse? any help would be very aprixiated

    Separate it from the power cables. (If interference is your problem.)

    have you checked that your plugging into the correct port? if you can change the assignments of each port, have you checked that the one your plugged into is correct? and have you tried speakers on the extension cable to make sure that works?

    they are in correct ports since the mic is working. but i indeed havent tried the cable with other speakrers (i have two cables, one long and one small connected, and i have tried th small (it worked))
    BUT i have used enother speaker with its own cable directly into the pc and it didint worked.... i'm leaning towards interfiaring with the amplifiers cables...(will try to see if that will solve it today)

    okey so. i bought a new sound card and works. But still i get the buzzing sound as background noise..
    i have connected the inverter to the battery, and whn i start the engine the noise gets worse...
    i have tried many diferent groundings (as well as battery itself) and the noise stays exactly the same.... any ideas?

    well, inverters can be problematic because of the A/C signal, but it could also be a ground loop (you'll need to search, my keyboard hates me for retyping the troubleshooting steps)...

    no its not a ground loop.. i checked many diferent groundings(including battery)... i also have tried enother battery so its not a batter prob either.. so.. inverter, or pc itself??.. can u tell me if its possible for either?
    i am also thinking, for beating the sound, to put a hpf on the sound system. but then i will win it only in sound... does it go to the usb and screen as well??? cause my touch dosent work either...

    I FIXED IT!! IS there a way , i can say in the post that its fixed, so it could help others too?
    anyway... what was faulty was the Power supply of the pc.. i dont know why. But i cut open the cable that goes from the iverter to the power supply, and combined the ground one (the internal grounding cable)(going from the power supply back to the inverter) with a grounding in my car, instead of back. That took care of all the buzzing noises!!!
