I have a factory bose system in my truck hooked up to a wiring harness that has a blue/white amp turn on wire. I have connected this to the inner pin of the J6 connector on my M4-ATX. This does it's job sending a signal to the wiring harness and in turn to the amp to turn the bose amp on.
My problem is I get bad audio feedback until the PC boots to the windows log in screen. Once there the noise is gone and everything sounds crystal clear.
One solution I am working on is setting up the PC to "instant on". However it would be great if I could keep the amp from coming on until I am at the windows log in.
Is there a way to modify (increase) the length of delay for the thump pin header turning on the amp? Or did I fail at some point in my setup? I do not have the ground pin (on the J6) hooked up to anything currently.

Still no solution to this.
I did get a PCI audio card and it has greatly reduced the feedback. However, it is disheartening mini-box has not responded to my email yet. I have yet to hook up the J8 usb to the main board and try the software, but I'll give that a go after while if I don't hear anything else before then.
For now the audio card does a good enough job.
I would suggest using a 528T timer from Directed if all you need is a delay & the PS won't do it. I am using one to delay my glow plugs when remote starting. It has worked perfect for years.
You can get up to a 60 sec delay off this device. Install diagram attached.

The new audio card has actually eliminated the problem; There is still noise in the line, but it is very low and no different when in windows or not.
I will definitely look into this though--I'm an information junky and who knows when I might need it. Thanks!
