Killed On board audio. What happened?

[kameshss]

Hello guys!

 

I had a problem with my On board audio a while ago, that it was not working. Touched the Audio chip on the motherboard and found that it was too hot, so that it was not working. It was not any driver issue or anything. Even I performed Clean Installation of Windows and Ubuntu. So it was the chip itself. I don't know how it happened. But then, I bought a PCI Audio card and it was working fine. After like 6 months (before few days), my motherboard started creating tons of problems like usb ports were not working, north bridge was too hot.

 

So finally then, I had very old PC with Pentium D 820. So I used that PC for 2 or 3 days. Everything was working fine. Now all of a sudden onboard audio is not working again. Found same problem what I found on my previous PC. Audio chip was freaking hot. So I switched it off immediately. Both are OEM PCs. Both has a good PSU. Can't complain that.

 

Both the PC was connected on a spike buster. And that power outlet is leading to main current and it's also powered by Home UPS/Inverter. The Inverter has certified Pure Sinewaves (found that it's good for PCs).

 

What seems to be the problem?

 

I know it's not any PSU problem. May be my main outlet doing something to the PC?

 

Please help me out!

 Try using it without the power strip. Does the issue still happen?

what "audio chip" are you talking about...

 

and how do you know that its "too hot"

It's a new power strip. The Old strip was thrown away by my dad thinking that it created that problem.

Realtek Audio on the motherboard.

It will look something like this. Mine is ALC892. 

 

 

I tried same on my friend's PC. It's not that hot.

theres no definition of "hot" so unless you can give some exact temperatures theres no way of knowing that overheating is what caused the issues

just because its hot doesnt mean its what died

some chips go up to 50 or 60C with no problem

I'm sure it's not anywhere between 50 or 60. It should me more than 80. It's not normal that I know. Because as I told earlier, same problem happened with my previous PC.

if it was over 80 you would have gotten a 3rd degree burn and your skin would swell and fall off

 

this is why you need to use a thermometer to determine temperature, not "oh i touched it for 1.5 seconds and it was hot" scale

Coming to the onboard audio problem, can you find what's wrong?

 

I'm confused here about the problem.

I would say age of the morherboard.

Yea. But How did it happen twice in a row?

The chances of you having two audio chips on two different model motherboards die due to heat is so unlikely that its pretty much guaranteed not to be the issue.

 

Newer versions of Windows and old motherboards don't always play too well together when it comes to drivers.  That is the first place I'd start.  

 

You may also want to check your speaker system / wiring to make sure the issue isn't there either.  Speaking of speakers, what do you have connected to the PC?   Connecting a system not meant for a line level signal or speakers with the wrong impedance could also be causing issues.

Well, It's not the drivers. I guarantee that. I've been using Windows 8 on the previous one and Windows 7 on Pentium D board. Both are Realtek Audio drivers, They have full support for both chips and OS's. It's not the speaker either, I checked with two speakers and a headphone directly on the motherboard port (Also in FP connectors). All those are working fine on my laptop.

[Matt420740]

The only thing I can think of is you had speakers not meant for a line level signal, or with the wrong impedance, placing too much of a load on the chip.  Its the only reasonable thing I can think of that would cause 2 audio chips in a row to fail.

This is too deep.

 

Never heard of this before.

[Matt420740]

Deep yes, but important to understand when working with electronics, including audio equipment

 

Take note of the "Why are ohms important" section in the first link.

Thanks for the info!

Could be shorted somehow. I have tinkered with electronics for 2 years, and often burn myself on shorted transistors, chips etc

What on earth are you "tinkering" with to get burned often by shorted components? 

[spaiduhz]

Very bad luck? Also, are you also using passive powered speakers perchance?

Nope. AC connection.
