    Configuring a MOBO audio sub out.

    Okies I have just powered up the new mobo in the car and Iam ****ed if I can get it to output to my sub amps.

    It has 3 sockets on the back which are;

    Line in
    Line out
    Microphone

    Bastard thing is supposed to support 5.1 but ****s me how to get the subs to work.

    Microphone socket for obvious reason outputs zero sound, am running the 4 channel amp off the line in and out and is working perfectly, If I plug the sub amps into either the line in/out whilst Iam getting sound it is very muddy ****e, almost like the subs are trying to play full range.

    Any suggestions ?

    The mobo is an asrock g41m-gs3

    Should I connect a front panel header and run the subs from that ?
    Would still be full range though wouldn't it ?

    do you have the realtek software installed? in most cases, you need to configure the software to specify which port you want to be the sub out..

    i know you're a bloke, but.. read the manual..
    it will say in there how to configure the onboard sound.
    usually line out = channel 1/2, line in = channel 3/4, mic = center/sub
    you will probably need a splitter and then work out which side of the splitter will be the sub

    Yeah Ive read the manual (several times).

    Been fiddling with it and under the realtek speaker setup thingo it all tests fines (FL/FR/RL/RR/Subs) and plays movies like a champ. seems it does not like playing music via 5.1.

    Connected as per the manual (same as your suggestion Sledge) on music the front speakers and the subs are working (subs only just) but no rear speakers, pull the subs and reconfigure it to "quadraphonic" and the front and rears are working fine.

    So all I really need to work out I guess is how to get the subs working on Quadraphonic and also be able to raise or lower the sub volume independently.

    Did you use a splitter like shown? If so, did you try both sides of the splitter with the sub?
    Take a photo so we can see how you've got it..
    If it's playing movies in 5.1 and you get decent Bass when playing that, then it's probably all working fine, but the music probably isn't 5.1 audio, so it won't pass anything to the sub.
    If that is the case you probably need some other software to split it into 5.1 or 4.1 and it will then pass it through to the sub.
    Maybe someone with more knowledge can explain it better..

    with mine, i just got a 5 channel amp which splits the signal for me..

    I got the subs working properly now, I had the amps piggybacked (master/slave) as they have this feature, whilst they were working but for some reason they were not outputting 100% properly, I have them both configured as master now and the subs are cranking hard, would be nice to adjust the output of the sub amps independently but that is something I can sort later once it is all working correctly.

    Still only have front speakers working but will go grab some 3.5mm Male to 2 x 3.5mm Female Adaptors this afternoon. that should sort it out hopefully as re-encoding 700gb of music to 5.1 does not sound all that appealing.

    Interesting to note that when I used the pink (mic out) socket for the sub signal the PC was randomly crashing, only using the line in/out sockets now and it no longer crashes.

    Thanks for your input Sledge, greatly appreciated.

    I'm curious what amp your using? Does it have optical/toslink input? Or did you mean you have your computer set to default 2 or 4 speakers and use the RCA inputs on the amp? I just got a new motherboard with optical out and looking for a way to use it.
