Hallo, my ss56gv3 has some problems, no front/rear sound signal on back output connections but only on sub/bass output(mono) front panel card disconnected. I read somewhere that there are some jumpers to move in order to exclude front card sound output and get sound on back panel but I think not on this mobo model... I fixed this by keeping front panel card connected but this gives a CMOS checksum error (also with a new battery) if I keep the front panel card connected. So... no sound or sound with Cmos error... can some1 help me please? I'll be very thankful
