Do you think if I replace the Realtek chip with the same one, it will fix the sound issue? For the sake of comparison split loopback driving Etymotic HF5 through a dedicated heaphone amp built by a guy named Knut: I’m assuming thats the headphone out and not line out?

I downloaded and installed the Realtek drivers and it installed without trouble. They may be analog power pins that power the analog portion of the chip. Thanks a bunch IDT. Tested both AC97 and HD settings and still no sound.

I always have to use Vooodoo. Try setting the main output to headphone mode. I just made an order datahseet 2 of these on eBay. Since the audio output is working, I currently have no proof that this is abnormal….

Not the most accurate way however. Procedure Desolder the existing codec from the motherboard Clean off any bridged pads on the motherboard oops Add flux and solder new chip Inspect, then power on Here are close-up photographs of the removed VT chip and newly-installed ALC Blog Random stuff… Comments Posts.

Line out to line in: I think you really need to get the jack detection to work correctly. I forgot about this topic.

Figure 18 in the datasheet http: I would have thought the ALCs would work with AppleHDA datashest with some patchingsince dafasheet should be quite similar to the rest of the Realtek line of chips…. Chances are, some of the small SMDs on the board are 0-Ohm resistors for the VT version of the board and valued components for the Realtek version. Perhaps try testing the existing wiring first. Are the jacks not detected at alx889, or is the wrong jack detected? I finaly done it… replaced Via VTS with realtek ALC, and it is all detected and installed in windows, but it cant reconize any back panel or front panel jacks… i guess some pin i didnt solder good and that is why it cannot detect jacks….

This probably would not happen on the headphone output. All HDA chips should have very similar though not necessarily identical pinouts. I used the Chameleon bootloader MyHack.

Here is a link to the problem: I googled and couldnt find a straight akc889 to this one: It was auto-detected and configured automatically in Linux, and also works in OS X with the usual amount of headache. Hey quick questions for Henry, I was wondering if i could do this on an MSI G31 TMp21 board the chip on there is currently a ALCs and would like to get my Datashet working perfectly, this is the only thing standing in the way.


Could be as high as to ohms? The recommendation to update BIOS and then update the driver is darasheet catch-all. You might check if the various power pins have reasonable voltages including the LDO and VREF outputsand see whether the signal pins are actually connected to the jacks? Dataeheet only purposes i can think of for the ferrite bead and the other capacitors is either to stabilize the output against oscillation or to protect it against injected currents.

Does this mean No more support for older IDT audio?

I just want to ask what the best temperature on blower solder gun to mak the solder quick melting but not make the component damage? On this particular board, on Windows, I think audio comes out of the rear green jack if something is plugged into the rear blue jack to trigger the jack detection.

Hopefully I can hack it successfully when it arrives. I thought the BIOS has audio controller data or darasheet. I assume I need a 3,5 mm Y splitter with one male and one female connector at the split ends?
