Dead onboard audio... again?!

[stevo1210]

I have a PC here with an Asus P4P800S-X motherboard, anyway, everything works fine except for my onboard audio!
Onboard audio was working fine before I disabled it a few months ago to install my Creative PCI512 sound card. Today I removed the Creative and reenabled the onboard audio and it doesn't even get detected in Windows. I've even gone through the trouble of reformatting my hard drive and reinstalling Windows because I thought my Windows was screwed. No change at all. Even after a CMOS reset, the onboard audio is still not being detected by Windows XP. I can't understand why my onboard audio has died out. For the time being, the Creative PCI512 sound card is back in there.
Does anyone know how to get the onboard audio working again? Never have I had a completely dead onboard audio symptom. I have a Gigabyte 8IPE1000-G that has a faulty right channel and that's the worse I've been through with faulty audio.

Thanks.

Re: Dead onboard audio... again?!

Just get a cheap sound card or continue to use that Creative sound card, faulty onboard audio shouldn't be a big issue since cheap sound cards don't cost a fortune these days, and your Creative sound card should be better than the onboard audio in terms of sound quality.

Did you change any jumpers or BIOS settings to disable the onboard audio? Check the motherboard's manual.

Re: Dead onboard audio... again?!

I've known some boards where integrated components get automatically disabled if a particular pci socket is occupied with an external pci card. I would uninstall all pci cards, leaving only the bare minimum installed.
The other problem i've faced recently regarding onboard audio is the microsoft package needed to recognize some high definition audio chips. It seems these chips are connected through a new bus, and if you don't have the microsoft windows xp package neccesary to support that bus, you can't install the audio driver. But it doesn't seem to be your case, since it seems your audio chip is a AD1888, a basic ac97 codec without high definition audio.

Did you disable the on-board audio in the BIOS when you installed the sound card?
-
If so need to turn it back on.

Re: Dead onboard audio... again?!

I have reenabled onboard audio in the bios, still nothing is being detected in windows. I have also stripped all pci card except for agp card and the audio still isn't detected in windows. Oh, and now for some strange reason my usb ports don't work. I plugged a usb flash drive in and bios detects it but windows says it's an unknown device or sometimes it will detect the usb drive but it will say it malfunctioned with a 'code 10' error. I tried different usb drives with same effect. Is this a software or hardware issue?

Thanks.

no, I didn't change any jumpers. it's all bios controlled. i've checked the manual to confirm that. anyway, thanks for the tip.

thanks.

Re: Dead onboard audio... again?!

Well... misbehaving peripherals are usually a consequence of an overtaxed PSU. When out of the blue LAN or USB ports start to act out, a common reason is the PSU is on the way out, and can't supply enough amperage to feed the whole system anymore. Try another PSU. If you don't have one, try leaving the system with the bare minimum (only one hard disk, no optical drives, no floppy drives, etc.)

Re: Dead onboard audio... again?!

Solutions for your problem stevo1210:

1. Use a PCI sound card.
2. Use a USB 2.0 PCI card.
3. Check your power supply.

Those are three good tips or solutions to your problem.

Also, try updating the BIOS if it isn't already the latest version.

If Windows can see the USB gadget then it has power.
But if it has bad power windows may not be able to ID the device and then can't load the right drivers.

Sound might be doing the same thing.

I think you have bad/dirty 5v power on the board.
That could explain both USB and sound problem.

Re: Dead onboard audio... again?!

I agree with PCBONOEZ: check the psu in all cases and internal cables if front usb ports are the ones misbehaving.
Regarding the onboard sound, it seems that any PCI frequency different from 33 MHz causes the audio chip not to be recognized so check PCI freq in bios. Clear the cmos again and check battery voltage too.

Re: Dead onboard audio... again?!

The PSU is a brand new Delta Eletronics one that is rated at 350W. I bought it a month ago and has barely done 10 hours of use. But anyway, I will try and replug the ATX connector as it may be oxidised? There is no way I can think that my Delta PSU has issues.... unless my unit is a dud. But then again, voltages are in spec.

Thanks.

Re: Dead onboard audio... again?!

Delta PSU = very high quality

Now I suspect there is a fault on the motherboard. Try updating its BIOS to a newer version if it isn't already updated to the latest version that ASUS released for it.

If nothing works, the best and easy solution would be to use a PCI sound card and PCI USB 2.0 card. It's a regular-size ATX motherboard, so I wouldn't doubt it would be able to take two PCI cards.

Fake Delta (I think) - UL is "Sun Pro" out of China.

Re: Dead onboard audio... again?!

The fake "DELTA" power supply has a UL number of "E210743".

stevo1210, check the UL number on the label of your Delta power supply and see if it's really a Delta power supply.

Man... And I though only third world countries like mine had to deal with fake electronics.

Re: Dead onboard audio... again?!

I can't get to my the Asus PC at the moment. But I know it has a real Delta PSU because the PSU came out of an Asus ATX case and also has a "certified by Asus" sticker on it. It also look very boring compared to the Delta PSU on eBay and the sticker has no fancy text, just lain words that say : "Delta Electronics Inc." etc.

Thanks.

Re: Dead onboard audio... again?!

Then you might have a component mismatch. Maybe you're trying to power a motherboard that consumes mostly 12v power with a PSU engineered to deliver mostly 5v power.

Re: Dead onboard audio... again?!

This is strange, but I replugged the atx connector of the psu to the motherboard and my usb ports worked again. I haven't tested onboard sound yet, but I will give it atry tomorrow.

Thanks.

A bad connection of the ATX connector can sometimes cause mysterious problems.

If the onboard audio still doesn't work, chances are the onboard audio chip has somehow died and a PCI sound card will be the solution to that.

Yes.

[Talking about the metal, not the plastic]
The female side of the connector can be bent a little with a stiff needle or a pointed DMM probe to tighten up the fit. Not too much or it may not plug back in.
