Noise before Opus turns computer on

Hey guys, I have a strange one here that i havent been able to figure out.

When using my analog circiuit (from the line out on my M10000) i get this really hiddeous noise. Damn i should record this crap for you guys...in the mean time i will just explain it.

Here is what happens. I turn the car on and this loud alternator whine sounding staticy bass thumpy sound fades into full volume until the Opus has waited it's 5 seconds (or is it 10) and turns on the computer. At that very instant the hiddeous sound goes completly away.

What the heck guys... how do i get rid of this one?

i get the same sort of thing and also use onboard sound on a m10k

mine only lasts 1 second or less though and the sound isnt all that bad

that's the whole reason behind a turn on delay for your amps, until your soundcard is actually outputing you are hearing electrical noise, delay the turn on & you will eliminate this, hope this helps...

In that case i would need a 20 second delay.

Anyways i would like to fix the problem not find a workaround.

Come one guys think this one through with me.

The horrible noise stops as soon as the opus turns on the computer. What can i test/try to get rid of the noise on the analog line.

If i really want to get rid of the noise all i have to do would be to switch to my S/PDIF (digital audio line) Then i hear no noise until it is produced and encoded by the computer.

I would like to get rid of that noise though.

Anyone with any bright ideas
