i am buying this HD audio output module for my desktop. i have 2 questions about it.
with HD aduio output system, when i insert 3.5mm headphone jack the main speaker should automatically turn off.... like a laptop or mobile phone...right??
and i see an extra power supply connector with the module.. why this connector? probably that extra power supply connector is optional.. but those 2 usb ports should get power directly from motherboard and audio ports also get all connection from motherboard. then why extra power supply connector? is this to increase the ampere of those 2 usb ports? it this is true then those 2 usb ports getting power from motherboard connector and at the same time also getting power directly from power supply.. is it ok? or there could be short circuit?
