I have just bought a new case with front panel USB ports, headphone and microphone sockets. I have managed to connect the USB to the mobo (a Matsonic MS8147C+) but I am having a problem connecting the headphone and microphone leads.
This is an image taken from the user manual:
The red circles indicate where there are some jumpers connected (the board came with these on).
To wire the microphone and headphone leads to the mobo I have to take these jumpers off, but when everything is connected I then find that I have no audio at all! No audio from my speakers or from headphones connected to the front panel socket. If i unhook the leads from the front panel and replace the jumpers, I get sound back through my speakers.
Even tho I am a bit of a NOOB at hardware it is not a case of wiring it incorrectly as I know which plug goes where (they are labelled the same as the pins), but there is no mention of these jumpers in the instruction book.
I don't know what these jumpers are for or if I should place them somwhere else on the mobo, when adding front panel sockets.
I have on-board sound disabled as I use a creative PCI512 in one of the PCI slots.
What am I doing wrong? Please Help
