I am connecting HDLED and such... my case has SPKR OUT L,R,and RETURN L,R but the mobo has SPKR, GND,GND and +5v. Also have MIC IN and MIC BIAS. Does anyone know about this? Sadly, the manual wasn't shipped.
I think these headers are for the case speaker, that is, the small one that gives beeps and beep codes. For front panel sound connectors you have to have onboard sound and those headers are located elsewhere. Sometimes they are near the I/O panel but the motherboard manual will say exactly where. Some separate sound cards support front panel connectors too.but the mobo has SPKR, GND,GND and +5v
