Another problem with Realtek HD audio

[Samson48]

Hi, I have just picked up my new PC 3 days ago and it has a Gigabyte Motherboard which is running a Intel Core 2 Quad with 4GB of DDR 2 ram and a GeForce 8800 GT Video card. The problem that I'm having with it is the Realtek HD audio thats on board, I am using a 5.1 system on it and find that I am hearing vocals coming from the SUB Woofer which I don't think should be happening, I have never had this kind of problem before and I have also installed new Drivers to see if it would fix it which it did not, I am at a loss and hoping somebody could help me find a solution to this.

Thank You.

Samson48.

have you tried re-tasking your audio outputs?
using your on-board sound manager?

ie: center/subwoofer,front,rear

what specific Gigabyte Motherboard model do you have?
(should support the 6 ch outputs for your 5.1 speakers).

Hi Turbo1, The Motherboard that I'm using is a Gigabyte S-series, it has up to 8CH surround on it, I have tried re-tasking my audio outputs to see if it would make any difference, which it did not, instead it made it worse and I'm still stuck with having vocals coming out of the SUB Woofer. It seems to have trouble mixing the channels into 5.1.

Thanks once again,

6 Channel Audio Setup

It seems to have trouble mixing the channels into 5.1.

ok,assuming your're using a PC speaker system,

disconnect all your cables/speaker plugs from the rear
audio outputs of the motherboard.

as well as your CABLES/PLUGS in your 5.1 speaker system
at the back of your subwoofer enclosure.

this time,before you plug in back your speaker cables at the back of your
subwoofer enclosure,re-check your speaker's manual on the audio inputs
(color coded),& ensure the cables are plugged in to where they should be.

then reconnect your speakers back to the rear audio outputs of your
motherboard.


6 Channel Audio Setup


STEP 1 :
Doubleclick the speaker icon at the icon tray to open the
Audio Control Panel.


STEP 2:
In the Audio Control Panel, click the Audio I/O
tab. In the upper left list, click 6CH Speaker.


STEP 3:
After plugging in 6-channel speakers to the rear
speaker jacks, a small window will pop up and
ask you what type of equipment is connected.
Choose a device depending on the type of speaker
connected (6-channel audio consists of Front
Speaker Out (Line Out), Rear Speaker Out, and
Center/Subwoofer Speaker Out) then click OK.


BTW: what model is your 5.1 speaker ystem?

Hi Turbo1, I have tried what you have asked, but it didn't change a thing, it seems to still have trouble configuring it self, I really feel a loss with this thing it doesn't matter what I do it wont correct it self. The Speaker system that I'm using is a Teak Home Theater System, I've used this same system on my old PC which was running an old Muse 5.1 card and it was fine, but this thing I have no idea what is wrong.

Thank You again,

so,you're using a home theater system,does it come with an AV receiver?

what type & how many cables are you using? ie : RCA,3.5 mm jack.

or are you using both via RCA with a 3.5 mm jack adapter?

so how was it connected to your PC?

ie: rear output (front,rear,center/subwoofer)


if you're using an AV receiver,please check at the back of the
unit (AV receiver) if it has a digital input connection for coaxial
or optical fiber.

if it does,you can use your motherboard's SPDIF connections which are
already built in to your motherboard (coaxial &/or optical fiber).

then on your sound manager,check the switch (radio button or check box)
for the SPDIF out.

if you can give the details or the model of your teac home theater system,
perhaps i can check the specs & see what type of connections it offers.
or you can decsribe the audio intputs of the speaker system,not sure if
it has a built-in amplifier or it uses an AV receiver.please describe
the audio inputs of the AV receiver as well.

Hello Turbo1, The System that I'm using is a stand alone home theater where the the amp is inside the Sub Woofer and it hooks up to the PC with three leads via RCA, L/R (Front), L/R (Rear) and Center, Sub with a 3.5 mm jack adapter at the other end for each lead, I've check all the leads to make sure they were all in the right socket, I didn't find the problem being here. There isn't any sockets for coaxial or optical fiber on the back of the unit either which most likely would have given me something to choose from, but it looks like I'll have to do with what I've got and hopefully find out what is causing the problem.

Thank you.

so,everything is plugged to correct audio ouputs.

& you used 3.5 mm (jack) adapter plug to each lead.

please ensure that the adapter plugs are not blocking to
one another.those adapters can congest the area/space
available inbetween the output sockets.& make sure that
the shoulder of the adapter plugs are touching the socket's
base.if a plug is not inserted althrough in the socket (center/
sub) you wont get the full bass/low response.

to check,disconnet the rear speaker out & front speaker out leads,
leave the center/subwoofer speaker out plugged in.

play a music & check if you can now get the full bass/low response.
(no vocals).

if that didnt fixed the problem,go to your sound manager & check if you can
see any sliders (looks like an equalizer) that refers to front L/front R,rear L
/rear R,center,subwoofer adjusters.

drag down the center speaker slider to your desired volume.or you
can turn it all the way down.

also turn off any sound effects & test the sound again,post back & describe
what is the sounding at the minute.

Hi Turbo1, This is what I did I brought myself some new leads to plug the Sub into the PC thinking that was what it needed, there isn't any adapters on any of the leads now, what I have is a RCA to a 3.5mm plug instead connected to the unit. I have tried it out to find it made no difference, I can't see it being my surround package causing the problem here since I have tried everything to remedy it. I have no idea now what to do next apart from having to go out and buy a surround card for my PC to cut of the on board surround. Is there any other way I can get around this.

Thank You,

right,that's better.now that you narrowed it down,
we can now check if your sound card's sound chip
really throws vocals thru your sub speaker.

having a PCI sound card is better though.

first,take off again all the leads from the rear output
sockets of your motherboard EXCEPT the lead of the
CENTER/SUBWOOFER.

when done,pull the RCA plugs out (at the back) from your
subwoofer's input sockets.

remember,those RCA plugs are not left or right channels
(white & red or black & red).one of that plug is the
CENTER SPEAKER LINE & the other one is your SUBWOOFER LINE.

with that 3.5 mm jack plugged in to the center/subwoofer (only)
ouput & the RCAs not yet plugged in at the back of your
subwoofer enclosure,adjust the volume controller of your
subwoofer to atleast 30 percent or to a level that you think is
enough for you to hear the sound clearly when you play a music.

now,play a music.then plug ONE of that RCA into a socket,
(at the back of your SUB enclosure) when you didnt get a sound,
plug that same RCA to the other socket.& when you get a sound
but too loud or noisy,then thats your CENTER SPEAKER LINE.
(mark the color of that RCA plug).

then test the other RCA & do the same as above.you should get
only ONE channel for your SUBWOOFER.now,when you get the subwoofer
line,you should only hear a pure BASS/LOW.you can increase the volume
for you to hear if any vocals is injected.

if you can still hear vocals through your sub speaker,then your
sound chip is designed to do that process,as it's obviously
your sub speaker is the ONLY connected where you can hear a sound.

when done following those steps,please post back & describe how was it
working at the moment.

Hi Turbo1, I took a different look at my problem today, a friend of mine has a Logitech 5.1 surround system that is made for PC's and I tried my PC out on it and what I had found was interesting, my friends surround system did the exact same thing as my surround did by having vocals coming out of the Sub, So the problem is the on board Realtek surround chip not my sound system and there isn't any updated Drivers to fix this problem, it looks like I'll have to go out and buy myself a 5.1 surround card.

Thank you for all your help in trying to find what the problem was, I hope that one day I can do the same for you in return.

you're welcome...

good decision for an add-on sound card,go & get it.
and have a REAL nice kicking bass! :grinthumb
