Windows 7: Realtek HD Changing Jack output reassignments ( FIX )

unfortunately this is a driver issue. Try uninstalling the driver, remove all Realtek driver inf's. Reboot, ignore the hardware found, install the driver again. Reboot and keep your fingers crossed

windows 7


I've read the whole thread but I'm still unable the fix my problem, which is the following.
I have an Acer Aspire 5672WLMi notebook, which has a Realtek ALC883 soundcard in it, if I'm not mistaken. This soundcard has 3 jack pins: a 2in1 stereo and spdif output, a mic input and a line input.
My problem is with the stereo/spdif output, because I kinda broke the jack plug out of the socket, and it has stopped functioning .. at all. The internal speakers are still working and when I try to connect a headphone to the output, there's no sound in it and the internal speaker remain working.
So an output change would overcome this problem, but I can't apply your methods to my scenerio. It is so because I don't know which speaker to assign to which pin?
Can you help me with that, please?:)
Driver: Realtek 2.27
In the registry there's a key named Drv5874_DevType_0883_SS10250094.
In the Playback device list there's a "speaker" and a "realtek digital output" entry, nothing else.

Obviously you cracked the motherboard. if you're any good at soldering you can try to re solder the leads on the motherboard. Use a good earthed iron.

SPDIF is numerical so you can't connect speakers to it. You can connect the spdif to your amp if it has a coax input.

Otherwise your options are a trip to a repair joint.

I did partially open the machine to get a look at it, and I'm pretty sure it's still attached to the motherboard. My best guess is that one of the metal contactor broke off and therefor the system do not recognises the attached jack cable (and even it did the missing contactor would prevent the signal to be transmitted - obviously..).
I don't want to replace and solder any of the parts if it's possible to re-task the pins via software.
So my goal for example would be to change the line-in jack input to an line/headphone output. I installed the drivers for the sound card with the propriate software - called audio manager (acer audio manager, which is basically the realtek audio manager). I figure there would be an option the reassign the input/output, but this feature is unavaible in my software. So I need a "tecchy" solution, which is this thread was originially about:) But like I said, unfortunately those registry tweaks do not work
Please help me, I'm going nuts, and I'm really trying to avoid the so-called trip to the repair joint

Thats a major assembly, ring zero software job. You could buy quite a few new pc's for the cost of a job like that.

The pc minijack contains a circuitbreaker which signals to the motherboard that a plug is inserted. Either the minijack female is broken inside, or on the the motherboard. Minicracks are mostly invisible to the naked eye.

You can
a) replace the minijack
b) rewire the motherboard minijack to a stock female exterior jack connector using a stereo shielded cable
c) go to a repairshop

I think you misunderstood me. By "pin" I was referring to the inputs/outputs - as seen in this thread's opening post.
I'm trying to achieve something that is possibly by a feature in other sound manager applications/drivers - and that is the changing the plugs pinout assignment. (the reason is the broken lineout jack output, but it's kinda irrelevent at this point).
I'm hoping the achieve something that is said in the first (Realtek HD Changing Jack output reassignments ( FIX )) and the 15th post (Realtek HD Changing Jack output reassignments ( FIX )).
I really hope I'm not confusing and you can tell me what to do (to get some sound signal out my damn notebook other then those rubbish speakers:)).
And big thanks for the replys so far!

all i know is that realtek HD lets you choose between regular AC97 output on the jackpanel, or as a surround output.

The only thing you can do in Sound Manager, (Device Advanced Settings) is mix the a front and rear panel.

Some boxes come with a sound panel in the front, and the motherboard has its default panel. Then you either split the sound over the different panels or join them.

On my motherboard i can choose to set the realtek chip to output regular AC97 connections on the motherboard panel, or a full surround .
That way all 3 jacks are set to output only on the motherboard and the inputs will done via the front panel.

A notebook has no such feature (to my admittedly limited knowledge) so you'll just have to make do as described before.

Again, sorry. Be brave, buy a small soldering iron, female minijack. Thread the stereo shielded cable through the hole of the original broken jack, solder the 3 wires and that way you're done.

"Pin00" = Rear Green-Coded "FR FL" jack
"Pin01" = Rear black-coded "RR RL" jack

"Pin02" = Center/Subwoofer
"Pin04" = Mic-In

"01 00 00 00" = Mic-in
"02 00 00 00" = headphones
"04 00 00 00" = Front speakers
"05 00 00 00" = Rear speakers
"06 00 00 00" = Center/subwoofer
"07 00 00 00" = Side speakers

Example if i want "Pin01" = rear black-coded "RR RL" jack to be front speakers all i have to do is Pin01 - 04 00 00 00.

Atleast now i can change the ports by editing the Pin binary numbers! . If you can't change jack output assignment this will fix it oh and it sounds great ., i turned my Center/Subwoofer to front speaker out put so my rears are stereo just like my fronts and not speaker filled rubbish
Many Thanks for this!

after fiddling some directories

I found the pinouts at:

and then added a new binary value
for the Pin01 and Data as:
04 00 00 00

when i tried to change the mappings, nothing really ever happens. when i close windows registry, it doesn't ask me if i want to save any changes or anything,
my pins are in a different folder too: it's not the one you gave, but Drv5874_DevType_0662_SS18493662
