Scrambled Noise At Higher Frequencies part 1


BlackMaterial

Good day Win7 Community,

This is my first post on here, as many users, I come here because I am having an issue.

I bought my new computer at friday.
I began installing my desired programs and games.
But as I progressed I found out something was going on with my sound.

I own a 5.1 surround sound speaker set so I'd like to use it, I believe I have stereo sound on it right now because I want my speakers to have sound all the time instead of having either music or voice-only.

On to the issue;

At first, I used my audio outputs of my motherboard, but that didn't really work well with my speaker set.
So I got my old 5.1 surround card (PCI) out and installed it into my new computer and plugged my speaker set, I could now use all 5 speakers.

I uninstalled the motherboard sound drivers and installed the sound card ones.
Fiddled with the settings the way I like it (sound volumes on each speaker)

I got it all working.. only, with youtube,WMP,VLC Mediaplyer, whatever produces sound.
When a high frequentie sound comes along, it gets scrambled which really ruins my fun of my new computer.

List of hardware/Software:

Motherboard: ASUS P8H67
Sound Card: Trust SC-5100 5.1 Surround Sound Card

Motherboard Sound Drivers: Realtek High Definition Audio Driver

Sound Card Driver: Trust 5.1 Soundcard 14319

Recap:
I uninstalled Realtek and installed the trust 5.1 sound card drivers.
I tried fiddling with WMP's settings etc. but no luck so far.

I hope someone can assist me in this struggle.

EDIT: It is now occuring 90% of the time on the low-middle frequency.. it's getting on my nerves.

PS. I will be heading off to bed about 5 minutes after this message is posted, it's 4 AM and I've been trying to fix this problem of mine since this morning.

Regards,
BlackMaterial.

I know its obvious but did you remember to disable the onboard (motherboard) sound chip in the bios?

What What What?

I might know a lot of computers and OS'.
But this isn't to my knowledge.

Please explain further, for the record, I haven't done anything else than described in the story above.

Thanks for replying.

Just try it then.

I don't know how onboard sound chip can be running at the same time as the sound chip on the sound card so 'disable' it in your bios.

Did you let Win7 download the drivers for the soundcard from its servers?

No, I went to the website myself, making sure I got the 64 bit version.

I have no idea how to actually disable this sound chip?

I've never, ever, been in my BIOS, too afraid I mess something up.

Could you tell me what to do and how I disable this chip so I can enjoy my new computer?

If you fill out your system specs, then we may be able to help you. Without the system specs this is difficult to impossible.

If you need help finding your system specs, then download and run this;

Speccy - System Information - Free Download

Regards....Mike Connor

BlackMaterial

Thanks a lot for responding Mike Connor.

I've just updated all my system specs.
Wasn't all too hard, didn't have to use 'Speccy' though.

Status Update;
Defining scrambled,
Not the correct frequencies that sounds are transported on, they are either lower or higher, they fluctiate, which is quite annoying.

If any additional information is needed, it will be provided.

Regards,
BlackMaterial.

Mike Connor

OK. Here it is;

Power4Pc - Asus P8H67-M v3 moederbord (90-MIBEBA-G0EAY0DZ)

To disable the on-board audio, ( which is necessary if you use a separate audio card), you need to go into the BIOS and set it to disabled.

When the machine is starting press the <DeL> key repeatedly until the BIOS screen appears.

Disable the on-board audio, save and exit. DO NOT MAKE ANY CHANGES TO THE BIOS IF YOU DON'T KNOW WHAT THEY ARE!! Doing so may disable your machine.

Regards....Mike Connor

BlackMaterial

Is there some step-by-step guide?
I have never been in any BIOS.

I tried to acces my old computer's BIOS, but it asked me for a password, since I did not know it, I couldn't acces it.
Is there a chance there's a password on my current pc's BIOS?

If so, what might that password be?

PS, This audio card I am using, this is the card I have plugged in my 5.1 surround sound, so this requires me to disable the onboard audio? (just to get any doubts out of the way)

Regards,
Blackmaterial.

If you did not set a password, and it is your machine, then there is no password.

Yes, in order to use an audio card, you have to disable the on-board audio chip, as it will otherwise cause interference and other problems.

The BIOS ( Click on the blue link for more information), looks something like this, but varies a lot on different machines, and depending who wrote it;



You can just go into it and set up whatever you need.

Regards....Mike Connor

BlackMaterial

Alright, that sound fine.

But I am a tad bit afraid I might press a wrong button in there.

Where do I find the 'Enable/Disable' switch in the BIOS?
Is there a:
Standard CMOS Features -> Sound -> etc.?
guide?

Kind regards,
BlackMaterial

You could read the manual which came with your machine, everything is explained there.

There are also various beginner's guides on the net, Like these;

BIOS for Beginners : Introduction

http://www.educypedia.be/computer/motherboardbios.htm

Once you are in the BIOS, there are also short guides which tell you what to do and how to do it.

If you are afraid to use it, then you will be unable to solve your problem.

I decided to just do it
I went into my bios, had to search a bit, but I found it.
I disabled it, saved and reset.

However, The problem still excists.
It's a weird problem to describe.
Let's say a tone, (example; a guitar)
Has to be right in the middle, but instead of producing a middle-tone, it produces a mixture of low and high tones.

Really hard to describe.

I hope I can solve this problem any time soon.

Do your speakers work correctly on other equipment?

Do they work correctly if you set them to stereo?

Regards....Mike Connor

BlackMaterial

They worked correctly on my old computer.

They are currently set to stereo.
I have difficulty setting Windows Sound (Control Panel --> Sound) correctly AND my drivers for my speakerset.
I can set it to stereo in both Windows Sound as in my driver.
And, I am getting confused.

Could you give me some suggestions such as;
set X as Y etc.

I hope I don't ask for too much.

I think you are trying to adjust too many things. I am going to look through this whole thread again and see if I have missed anything. I will be back as soon as I have a solution............

Regards....Mike Connor

BlackMaterial

Thanks for staying with me Connor,
I am 80% sure I am doing something wrong myself.
And 20% sure something in the computer itself is wrong.

On a side note;
I get sound out of all 5 speakers and 1 subwoofer, that means that the hardware is installed correctly and works fine, correct?

Regards,
BlackMaterial.

Mike Connor

Open your "Control Panel", and choose "Device Manager";

You should get a window like this. When you click on the small arrow next to "Sound, video and game controllers" ( I have marked this in the image), what does it say?

Not necessarily. Some things work, but only poorly when they are not set up properly.

This it what it says.

This.

Mike Connor

Click on "properties" for both devices. Post the screen shot.

BlackMaterial



Result.

Mike Connor

OK. You have not disabled the on-board audio in the BIOS.

You can disable it in the device manager. Right-Click on the AMD device, and choose "Disable".

BlackMaterial

That's a bit worrying actually.

Than what did I disable?
I saw something with Realtek HD Audio.

Anyway, I'll try and Disable it through here.

Will post result in 5 minutes max.

Mike Connor

There is no rush, take your time, and note what you do.

Realtek HD Audio is a VIRTUAL device. Basically controller software. Not a piece of hardware.

The AMD audio device is a CHIP on your motherboard.

I am unable to post actual BIOS screenshots, for obvious reasons.

Anyway, after disabling the device, close all windows, restart your PC, and see if that has solved the problems.

BlackMaterial

- Restarted after disabling the Device through the Control Panel
Problem still excisted
- Shut down my computer, opened it up and removed the Audio Card and mounted it back in (Same PCI Slot)
- Started my computer up.
Problem still excists.

Any more idea's?
The audio can also be described as trembling, scrambled, like the speaker have the sniffles.

.. This is tiring.

BlackMaterial.

My suggestion would be to remove that card, and use the on-board audio.

Either there is a fault on the card, it is not completely compatible with your board, or the drivers are faulty.

Trying to troubleshoot things like this can be somewhat wearying, it is the nature of the beast. Also, all I know is what you tell me.

I don't know what you disabled in the BIOS, but I suggest you re-enable it.

Regards....Mike Connor

BlackMaterial

I laughed at 'it is the nature of the beast'.

Anyhow, ofcourse when I first got my computer I tried using my motherboard audio ports for my 5.1 surround sound.
but that didn't really work, since i didn't get my speaker set to fully work.

But it might be better to use my motherboard outputs or perhaps purchase a new audio card..

I can question myself; why must I endure such problems if i spent so much on a good computer.

What do you advise at this point?

BlackMaterial

I would advise you to use the on-board audio in stereo mode for the moment, and look at getting a new card to support your 5:1 sound system.

Regards....Mike Connor

Mike Connor

You can also get external audio devices that will do that nicely;

external sound card 5.1 - Google Search

Regards....Mike Connor

BlackMaterial

Hello again,

I'm tired and hungry, but, no sacrifice, no victory.

Steps I took:
- Removed Trust SC-5100 5.1 Surround Sound card from my computer
- Hooked my 3 cables of my surround sound in my motherboard.
- Went into the BIOS and enabled the ding I disabled. (HD Audio)
- Went to Control Panel -> Device Manager and looked at Sound.




Result of this change:

- No more crackling sounds, dips, valleys or helicopter flights.
- Only my front left and front right speaker work.
Already went to: Control Panel -> Sound
- Configure speakers -> 5.1 surround (rear), went through the entire process.

All I need now, is to get all 5 speakers working at the same time.
And I'll be happy, once more.

Little victory, but we're not there yet.

BlackMaterial

Very good. Make sure your on-board audio supports 5:1 sound. Many only support stereo.

Regards....Mike Connor

BlackMaterial

How can I be sure it supports 5.1?

Every plug from my 5.1 surround could be plugged in, in the corresponding coloured entries.

I haven't installed any drivers for my sound, if I look in my Control Panel -> Programs and Features
and there wasn't any either.

I remember something like 'Realtek HD Audio'
But I want to solve this issue, seeing as it already is 02.30am.

Any idea's or tips on the correct drivers? ( What is that AMD High Definition Audio Device btw?)

Regards,
BlackMaterial

Mike Connor

AMD Chipsets for Desktop PCs

You need to look at the specifications for the chip on your board. If it supports 5:1 Sound, it will say so in the specifications.

Just because you can plug everything in does not mean things will work as you expect. You have to set it up properly.

You have to do this slowly and methodically if you have never done it before, and you need to carefully note what you are doing.

If you keep on adding variables to the thread we will never get anywhere, and you will simply end up very confused.

Might I suggest you have something to eat, sleep on it, and we can continue, or start afresh, tomorrow?

Regards....Mike Connor

BlackMaterial

Thanks for the tip, haha.

I was already on planning on calling it a night.
I'll continue tomorrow night.

Be well,

Good Grief!

Look - go right back to basics.

Take card out after deleting drivers.
Uninstall any Audio progs you see in 'programs and features'
Delete all the audio drivers in "computer management"
Download a driver sweeper and get rid of extraneuos audio driver leftovers.

Reboot and either reinsert your soundcard/drivers (after disabling onboard audio chip in bios) then see if Win7 downloads drivers for it first

or use onboard sound chip/drivers.

Just to try to explain
(I'm still learning this gumpf so hopefully others can add a bit)

music = 2 channel stereo
(unless you run a special 5.1 SACD like Pink Floyd but you need a special DVD player that reads SACD's)
some cards have software that converts this two channel source to quasi 5.1/7.1

A 5.1 Game (audio) or DVD 5.1 film produces 5.1
So test 5.1 output with a film - not a music source

Good luck!

BlackMaterial

Thanks for responding neo101.

What I've done so far is written above.
I haven't even installed the Realtek HD Audio Manager back onto my computer and my 5.1 speakers DO work.
But only if actually supported by 5.1 sounds.

When you said 'Music = 2 channel stereo'
I looked up 5.1 sound test and I found some specifically made 5.1 sounds and tried them.
All my speakers actually work and even without crackling.

But my only 'issue' is.

Is it possible to 'disable' the true 5.1 surround sound and have every speaker play the same sound? (Stereo effect)

Regards,
BlackMaterial.

Mike Connor

No. The signals are different. Either you choose stereo, which will play anything, ( even "Mono" if no stereo channel is present) or you choose 5:1 which will only provide 5:1 surround sound if the signal is designed to do that.

Have you now solved all your issues with noise etc?

Regards....Mike Connor



BlackMaterial

The issues with noise have indeed been resolved, thanks a lot Mike, you too neo.

All I wish to know is how to set the speaker to 'stereo' or any other setting that makes all my speakers play the same sound instead of just 2.

I tried:
- Control Panel
- Sound
- Configure Speakers
- Stereo -> next->next->finish

Did not work?

Thanks again, hoping that I can get some advise on this one aswell.

Regards,
BlackMaterial

Mike Connor

In order to play something in 5:1 surround sound, then the signal you are using has to have the 5:1 sound encoded. If It does not, then it will not play those channels, because they don't exist in the signal.

If you set your audio devices to stereo, they will use any stereo encoding, and ignore anything else. ( Simplified explanation).

It is possible to get all your speakers to play the same channels, ( with a bit of jiggery-pokery and external wiring), but it will sound awful. The only way such surround sound systems can work properly, is if the channels required are in the signal. If they are not, it wont work. The system decodes the signal and sends the correct channel to the correct speaker. If the channel does not exist, then nothing happens. Most music is only available in stereo. Trying to play it on a 5:1 surround sound system wont work.

5:1 surround sound ( and other variations), are only useful for film soundtracks etc, which support the necessary channels.

For more information; http://en.wikipedia.org/wiki/Surround_sound

Regards.... Mike Connor

BlackMaterial

Than it's a mystery, because my old computer played any sound on all 5 speakers.

And, if what you're saying is true, than the whole point of a surround set is quite useless,
I was already tempting to buy a 5.1(7.1) headset soon, but this is only making me want it more O_O.

.. Scary stuff, electronics.

Regards,
BlackMaterial

Mike Connor

5:1 surround sound is only of any use to signals that support it. You can connect any number of amplifiers and speakers to any output. This will give you sound in all the speakers, but it wont give you surround sound, just the same signal on all speakers.

Regards....Mike Connor

neo101

I had a quick look for you and solution for

Stereo x2
Stereo x2
LFE .1

Right click Sound icon on your screen
> Playback devices
> right click on 'speakers' panel
go to 'properties'
tick 'speaker fill' in (menu heading) 'enhancements'

PS There is also something called 5.1 stereo "UPMIX" which converts a stereo source to quasi 5.1/7.1 (in either hardware or software)

Have a read about it!
Might need posher soundcard though which offers this!

BlackMaterial

I tried what you said,
It did enable all the speakers. Only the backspeakers are a bit low on volume + a little echo

I tried
>Right click on 'speakers' panel
> went to properties
> Tick 'Room Correction' in (meanu heading) 'enhancements'

It made a lot of beeping noises, trying to find the correct sound itself.
My front speakers' volume was lower and the back, was somewhat higher with a little bit of echo.

Can't wait for the headset

Regards,
BlackMaterial

BlackMaterial

I apologise for the double post.

I wanted to thank both Mike Connor and neo101 for helping me figure out the sound problems.

Even though not all 5 speakers are working all the time, they atleast give the correct sound they should.
I will look for a proper headset, which will suit me best on some of the following terms;
- Comfort
- Amount of 'build in speakers'
- Quality
- Price

Anyhow, thanks guys !

BlackMaterial
