Windows 7: Disable jack detection and device disconnected?

Disable jack detection and device disconnected?

Hi there.

I decided to test out Windows 7 and take it for a testrun and until now I have noticed a few issues I have let passes but this one takes the cake.

My jack detection is a little bit out so if the cable moves in a certain direction, it will detect it as the jack being disconnected and connected again with the slightest movement.

This was no problem with XP, it would still stream out audio throught the audio jack even if it detected that the jack was disconnected or not. In Windows 7, not so much.

If the jack port is not properly sending a message about it being connected, Windows 7 will disable it, shut down and disable every option for it until you connect it again. This is particle annoying when the motherboard itself has a broken jack detection and the only resolution is to buy a new motherboard.

In my previous case of the instant disconnected/connected, it will create an empty space of silence for like a 0.5 sec - 2 sec in the middle of the song.

What I was thinking is if it's possible to disable this behavior in any way?

I had the same experience when first using Win-7, it's the auto-sensing built in to the OS and drivers. Is your internal audio by "Realtek"?

In my case I sprayed the 3.5mm speaker plug with a small amount of contact cleaner and worked in in/out of the speaker jack a few times.

Yes, WinXP ignored the auto-sensing and worked flawlessly. Win-7 has several new layers (of mostly cr@p) built into the audio system.

If your audio device is Realtek, there is at least one related parameter that I know of. Open the Realtek control panel. Right click on the simulated input/output jacks on the right hand side. If you see "connector retasking" select disable the auto pop-up dialog check box. There is also a small folder at the top right, open and select "Disable Front Panel Jack Detection" de-select the auto popup dialog.
Don't know why but this seemed to stabilize my system even though these are related to inputs.
