Realtek HD: bug or hw problem?

I'm having a strange problem with my integrated sound card -Realtek ALC889A on Gigabyte GM-MA78G-US2H motherboard-. Without having any connected device, the realtek manager always shows two active connections (specifically in the black and blue jacks). I do not know if it's a hardware or software problem.



When I connect a device, the software usually detects it but in a wrong jack. They also appear frequently the messages "You just plugged a device into the audio jack" / "You just unplugged a device from the audio jack", but no device was connected physically.

I'm using Windows 7 Ultimate x64, and tried changing drivers (from motherboard CD, and Gigabyte and Realtek sites), but nothing seems to work.

Help please!

I saw THIS chipset driver for Win 7. If you don't have this motherboard chipset driver, download and install it. That would be my first step to try and fix the problem.

I installed the specific drivers for my motherboard from the included cd, and downloaded from the Gigabyte website. Note that my motherboard model is GA-MA78GM-US2H, not GA-MA78G-DS3HP. (Anyway, both use the same chipset). Thanks for the reply.

When I first set up my computer, Gigabyte motherboard GA-P35-S3G I also had false pop-ups with a lot of included static as the driver would reset as if something different had been plugged in. (don't know if this is your problem) I took a headphone jack and sprayed a bit of contact cleaner on it and worked it in/out of all the available 3.5mm input/output jacks on the front and back of the computer.

This cleared up the driver re-setting I also disabled the jack re-tasking and also disabled pop-ups.
(right click on the Realtek graphic of the I/O jacks)

Also, click on the small folder in the upper right of the Realtek driver, and look under advanced settings.

I find it much easier to make adjustments using the Microsoft mixer, right click on the MS speaker icon in the system tray... I then remarked out the Realtek mixer/setup control panel as it's unnecessary.

You could also make Stereo Mix the default recording device. (this records anything your computer plays)

One last thing... upgrading my BIOS improved audio performance even though the BIOS update mentioned nothing about audio tweaks.

I just upgraded the BIOS to version F8, but I still have the same problem: Ghost connections. I would have to try cleaning the audio jacks, anyway, I wrote to Gigabyte's technical service. Thank you very much, let you know if I have news.

One thing...
Definitely download and install the most recent driver (2.50) from the Realtek site.

I'm already using them, also tried with the ones from gigabyte's site.
