Checked the speaker and all connections to & from the woofer, I
still get no sound anywhere in the line. The line-out and headphones
have the same issue. I wiped the hard drive and reinstalled the newest
drivers to no avail, verified proper audio settings; system says the
device is operating normally, I can't even find where the audio card
is in this nightmare of a machine. Where do I go from here?

H?, You have a very good system...one of the best of SONY..SUB does not get activated automatically especially on STEREO mode.DIRECT STEREO Notes • No sound will be output from the subwoofer. .your system has Dedicated Power Amplifier for 2 Externally Driven Sub-Woofers (200W RMS x 2)..in order to activate the sub woofer amplifier you need to make a selection on the surround modes while you are switching the modes of the surround you will see the speaker position on the display of receiver as well..if you do not see the sub woofer it wont be activated..Sound Field Program (A.F.D) is a good example to test it.. Take care and please Remember to rate/vote and give me 4 Thumbs Up for Helping out the Community :) Hope this helps! -------------------- Additionally please follow the instruction on your user manual to activate the SUB ,as is follows.. ----------------- BASS-OUT
Low-frequency (bass) signals can be directed to the
subwoofer and/or the front left and right speakers
according to the characteristics of your system. This
setting also determines the routing of the LFE (low-
frequency effect) signals found in Dolby Digital or DTS
Choices: SWFR (subwoofer), FRONT, BOTH
• Select SWFR if you connect a subwoofer. LFE and
low-frequency signals from other channels are directed
to the subwoofer according to the speaker settings.
• Select FRONT if you do not use a subwoofer. LFE and
low-frequency signals from other channels are directed
to the front speakers according to the speaker settings
(even if you have previously set the front speakers to
• Select BOTH if you connect a subwoofer and you want
to output low-frequency signals from front channels to
both the front speakers and subwoofer. LFE and low-
frequency signals from other channels are also directed
to the subwoofer according to the speaker settings. Use
this function to reinforce low-frequency signals using
the subwoofer when playing back sources such as CDs.
i have found the specs to your amp.
1. Amplifier connections: Lets make things simple. As we look at the amplifier speaker connections, we will number the outputs 1 2 3 4 from left to right for the top connections and again 5 6 7 8 from left to right for the bottom connections.
1 should be connected to a positive (RED) (+) on sub woofer A on voice coil (a)
4 should be connected to a negative (BLACK) (-) on sub woofer A on voice coil (b)
Now using a small piece of cable, connect negative of voice coil (a) to positive of voice coil (b)
Follow the same procedure for the other sub woofer using 5 and 8 as 1 and 4
This configuration should make the amp run at 4 OHM BRIDGED x 2.
i hope this helps.
Use the left and right to connect the positive and negative to the respective speakers in the right and left. Please make sure of the polarity and so be cautious. next you can connect the sub woofer from the left and right channel as the amp is bridgeable. Use the lead to connect from the R- positve to L negative. test and check the phasing of the speakers, must get good low bass or else you can reverse the sub woofer and check again. If you ae having frint speakers connect accordingly the the other channel. Helpful Good day
configure ur PC (both OS audio and third party sound driver) for surround sounds. control panel- sounds and audio devices - speaker settings - advanced - speker settings. so this done. make sure u select the 6 input channel - the button is on the right edge near the volume knob. near the vol button there are two buttons for selecting input type with up down arrow. from that u can select the input type this will be indicated on the top front indicator. but with the 6 input channel selected all selections are preceeded. if u select stereo mode u will have left/ right audio only. make sure u connect the input right. connect from computer to 6 channel input. main, surround, center and sub-woofer. connect the spekers to main (L/R), rear(surround) (L/R), center and sub woofer to terminal marked sub woofer ouput. this done select like i said before the 6 channel button. that should do it.
If you have a 4 channel amp and 4 speakers and each speaker is connected to each of the 4 channels you are just fine. A stereo amplifier has 2 channels, typically labeled left and right and each channel has an amplifier. A 4 channel amplifier has 4 amplifiers. With one speaker on each channel, there is one speaker on each amplifier. Audio amps are referred to as amps or amplifiers, although if they have more than one channel it would be more correct to call them something like 'multi-channel amplifier' or 'multi amplifier speaker driver'. Semantics.
I recommend you swap your left and right input cables to make sure it's not a source issue.
So from your headunit, plug the left channel output into your amps right input and your right channel output into your amps left input.
If the same side is still not working then disconnect both (or single speaker if it bridged) the speakers from the not working side at the amp. Connect the front and then the rear speakers individually and retest to see if one of them works.
If one does work then check the cabling and speaker connections on the one that doesn't. If it's shorting out anywhere it will stop your amp from powering that channel.
Failing that, it could just be that your amp has partly failed.
