using subwoofer on sblive - GoFuckYourself.com

iwantchixx · 02-28-2003, 05:22 PM

I am aware that it is possible to use 2 stereo pwoer amps and 1 mono power amp to get the 5.1 surround on all sblive cards. However. The spdf out doubles as mono/center/sub out on the right channel. Yet the left channel is the data line for 5.1 desktop speaker sets. problem is, even on the analogue channel there is TONNES of fucking static. I can actualy hear the cpu working through my subwoofer. The lower I turn the master volume in windows, the louder the damn hiss gets. I turn it up louder and it kills the hiss when I have no music playing. Has anyone found a workaround to getting a clean signal out of the spdf/mono/center/sub jack?

go into your sound settings and disable the 20db mic boost

Almost sounds to me like you have a ground loop.

Try plugging the sub into a different wall outlet to see if the hum goes away. Or maybe your sound card is just fucked.

I plug my Audigy 2 card directly into my receiver using the digital output so noise has never been a problem for me.

it's not a ground loop. I hear data. The same sound you get when you first dial into your isp using dialup.

i figured it out, I had to short the red and white wires together to "tell" teh soundcard to cut off the digital signal
