-= Speakers problem after Cleaning CMOS =-

Recently I had to clear my cmos because I accidentally pushed out the surge protector's powercord of the outlet a couple of times, and the computer would start but the monitor says "dvi not detected" but it's working now however...

Problem 1: Ever since I cleared my cmos... my computer starts up much slower, it shows the "dvi not detected" on the monitor for a bit then starts the POST shows up.

Problem 2: Also, after cmos was cleared... my speakers stopped working also. Although my headphones still work. but when I change the default device to speakers... it doesn't work at all.

Steps I've tried to fix these problems:

- I've moved back the clear cmos jumpers back to the original placements.
- I've uninstalled/reinstalled latest realtek drivers
- I've unplugged/plugged and checked if my audio jacks were working.
- I've plugged my speakers into another computer/laptop and they are working fine so it's not the speakers itself.

Could I have moved something on the motherboard without noticing it while moving the clearcmos jumpers?

Any suggestions? I really don't want to reformat if I don't need to.

 

Hi and welcome to Computer Help Forums.
You don't normally lose your audio for the reason you described.
Have you been into the Bios and reset time and date.?
Have you installed all your Windows updates?
What yellow icons are showing in Device Manager?
Are all your drivers up to date including chipset drivers?

What started all these issues as I am thinking this is a reinstall gone wrong.
Please answer every question so we can assist you quicker and have you up and running again.

 

I have an idea or two but they are ALL based on your answers to DSTM. Did this happen after a re-install.

 

I did not re install anything other than re-installing realtek. And what are chipset drivers?

I've went into the bios but the time and date were already updated.
All windows updates are updated
No yellow icons in device manager

 

No this only happened after I clearned cmos... nothing else. I didn't do anything else before that.

 

Are chipset drivers... the motherboard drivers? If they are... I haven't updated any of them or reinstalled anything for them. My video card driver I haven't reinstalled yet either. Don't have a soundcard.

 

Hi, I recently had some odd problems due to time settings. Because you cleared the CMos, your times may need to be synchronised to internet time again, in my case it messed with my E Mail but who knows?
Try this first as no harm will be done.

Click on the clock on the bottom right, a window should open and at the bottom will be "Change date and time settings" click on that.

Another window should open for date and time with three tabs, click on the "Internet time" tab, then the "Change settings".

There is a drop down type list, make sure it is set to "time.windows.com" then click on "Update now", that will then check the internet time and synchronise with it.

Hopefully synchronising may cure other problems even if sound doesn't come back.

Although it didn't fix the sound, I appreciate your help.

 

Yes, the chipset drivers are PART of the motherboard drivers. Since you don't have a sound card your audio must be on the motherboard. The audio drivers could be separate from the chipset drivers or everything could be bundled together.

Since you only cleared the CMOS driver installs should not be needed but can't hurt. More to the point would be to go into your BIOS and make sure that on-board sound is enabled.

 

I've re-installed chipset drivers, went into the bios to make sure the sound was enabled. Installed audio drivers. Still doesn't work.

 

All drivers need to be installed regardless. Without reading back has this system got a graphics card or onboard graphics?

 

670 gtx nvidia gpu.

 

This is the Graphics driver you need.

http://www.nvidia.com/object/win8-win7-winvista-32bit-314.22-whql-driver.html

Many a time my audio has been restored by installing the Graphics driver.
Download to your desktop and then install.

If you watch the install progress bar during install it normally shows correct audio drivers being installed as well.

 

It's not muted...

Yeah I just did a reinstall of the latest nvidia driver. Should I not be checkmarking the nvidia audio driver? Should I uncheckmark that? Cause after reinstalling it... it still didn't do anything.

Also the version I need is a 64 bit one... which I already got.

 

After reinstalling the Graphics Driver you are asked to reboot your Computer.
Hard to give advice re drivers when you haven't mentioned till now you are running X64 Bit.

 

Hum, reading back and having a good think about this, I notice right at the start you mention the headphones work, but the speakers don't? Is this still the case?

if so, then I think we may be chasing a red herring as they say, if the headphones work and you can hear sounds from them, the main audio system must be working OK, and therefore not a driver issue at all.

You also asked if there is a possibility you disturbed a connection on the motherboard while changing the BIOS link to reset it to default settings, this is a very big possibility that the wires for the speaker jack may have been disturbed as they connect to the motherboard, if for a front case mounted jack.
Or if the jack at the rear is directly connected to the motherboard, the connection on the board may be a poor one.
to check the connection for a directly mounted jack, will mean removal of the mother board though.

If you are confident in removing the motherboard from the case, let us know as there will be a heck of a lot of different cables and wires to un-plug, you will need to take note of where they go, and sometimes is best to take photo's if you can, so you know where they go back to. Though in most cases, all plugs are different, so cannot go back on the wrong place.
If the connection to the speaker jack on the board is looking suspicious, or even if not, you will need a soldering iron to sort the connection out.

To carry Nev's last post one step further make sure that, under sound in your control panel, speakers are selected as the default, not the headphones. This is especially critical if your headphones are USB digital, not using an analog 1/8 inch audio jack.



To change the default setting just click on the device that you want and then click on 'Set default' at the bottom.

I go through this crud a lot as I have three sound systems going between the actual sound for the laptop and HDMI audio to the HDTV and then wireless HDMI audio to my bedroom.

 

@Nev. Resetting the jumpers to suggest removing the Mobo and may need a soldering iron is premature.

Can depend on your Motherboard. Have you a Realtek or Nvidia control Panel?
Normally it shows in the control panel or an Icon in your system tray

 

Yes DSTM, a bit premature perhaps but just thinking on my feet as it may be needed in the end, hope not of course, though you never know.

As yet, unless I have missed something, it would perhaps help if we knew a bit more, as all we know so far is the make and model of graphics card. So can you tell us please what make and model the computer is, or if a self built one, the motherboard make and model, and it may help to know the make and number of the CPU or other details.
Knowing which motherboard will help in researching which sound system is fitted at least.
