Sound hooked up, having USB and popping issues
I am running my sound card to the trunk of my car using a 15ft USB cable from the glovebox. I found out that I can't power my eq's signal if I am going through a hub on the end of that line, but it works if I am on the line directly. Since I can't explain much well, here is a diagram of sorts:
Glovebox >>>> 15ft USB line >>>> Creative Labs Sound Blaster MP3+
Not working configuration:
Glovebox >>>> 15ft USB line >>>> Unpowered hub >>>> Creative Labs Sound Blaster MP3+
Does anyone have any suggestions? If a powered hub works, how should I power it?
Also I have an issue is the sound card and the amp with popping. I have my amp and eq running off of the ignition line that comes off of the M2-ATX so it is delayed so I am not supposed to have a pop. When I start the system, I do not get the pop. It is when the sound card cycles the driver or something when I boot into Windows. Is there any fix for this? Should I get a pulse relay delay and set it for like 45secs to let the sound card sort itself out before the amp powers on?
Thanks for the help. After months, I am so close!!
