Sound only coming from one port of the sound card.

I failed to realize this until just now, but there are 3 ports to the sound adapter on my motherboard and only 1 is working. I have the M10000 motherboard, using the onboard sound and it's the middle port that's providing sound right now. The top port doesn't do anything and the bottom port for the subwoofer isn't doing anything. I have the sound set up for 5.1 in the Control Panel of Windows.

What's the source for the audio? Is it just stereo (i.e., front left and front right)?

Well the M10000 has 3 ports, a stereo front, a stereo rear, and a microphone. So that's left/right for front, left/right for rear, and the microphone can be changed to a subwoofer.
I'm sending audio out of the 2 stereo jacks into a 4 channel amp, and out of the mono jack to a mono amp for the sub.

You have to install the soundcard drivers after that you will be able to enable 5.1 compatibility on the property tab of your soundcard properties

UWAHHHHHH? Where do I find the soundcard properties? In the system tray? I thought I did install the drivers for the motherboard, almost positive I did. I'll check for that properties tab and see if I can change it. Thanks.

I believe it will be sub and centre channel. Remember it's a 5.1 configuration coming from the OB AC 97 codec, not 4.1

You'll have to grab the sub portion of that output and leave the centre channel behind if you're not intending to use the centre channel.

**Maheriano** · 08-19-2006, 09:30 PM

And I imagine that option will be in the sound card configuration?

I read other threads where they're talking about line converters, and the center/subwoofer splitting, and power issues. Can I even do what I'm trying to do with what I have?

I believe you're still on the right track. Remember that each of one of those MB outs has 2 signals in it. Your taking each of those outs and sending them to their respective places on the 4 ch amp - front L/R and Rear L/R. The 3rd out having the centre and sub signals will have to be distinguished/separted. Meaning you have to find the sub signal from that 2 signal line and send it to the sub amp. The centre channel signal will just not be utilized - right? And that's OK. As far as determining which is sub signal and which is centre signal from that line. I think I'd have to experiment with the amp output to determine if the input signal is full range (centre) or low(sub). You won't kill the sub speaker if the centre channel signal was sent through if the volume isn't cranked up. You're doing it right so far. Don't doubt yourself.

UPDATE
I looked everywhere for a GUI to configure the sound card, it doesn't exist. All I have is the sound option in the Control Panel and I have the sound set to 5.1 there. That obviously isn't working. But when I opened the volume settings, and went into advanced, I enabled the Smart 5.1 Surround and my sub thumped for a half second. But when playing music, no thump. I turn the Smart 5.1 on and off and it thumps again, but it won't actually thump for music.

The amp gain is up, the remote bass knob is up, the subwoofer volume in the computer is up, and the bass in Road Runner is up. Still no bass. But when I remove the 1/8 adapter from the mic slot of the computer sound port, the sub thumps as the plug is exiting and entering. Not thumps, but makes thumping noises. This is all while music is not playing.
