Frequency response from 40 Hz to 15 kHzdB: I think you really need to get the jack detection to work correctly. Email will not be published required. The audio dafasheet is a Realtek ALC right?

Again for comparison, Sansa Fuze. 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 Have you tried plugging a jack into other ports to try to trigger the jack detection?

The DC blocking capacitor is before the header for the cable, but everything else is on the cable. Those that I tested rear microphone and rear line out work fine.

Hopefully I can hack it successfully when it arrives. Was it salvaged from another mobo or did you specifically order one in? Line out to line in: I used a multimeter to test the SMD resistor.

I assume I need a 3,5 mm Y splitter with one male and one female connector at the split ends? It was auto-detected and configured automatically in Linux, and also works in OS X with the usual amount of alc8889. I suspect this was a driver port assignment bug rather than due to the hardware swap.

I think you could play some Hz sine wave e. For the sake of comparison split loopback driving Etymotic HF5 through a dedicated heaphone amp built by a guy named Knut: You are right it is connected i checked with multimeter following evreything to the end, pin 14 and 15 goes through two uf capacitors then through some resistors i think or something else and goes to Front Panel Audio Connector and then it goes in front headphone panel jack and i followed everything so it is connected.

Have you tried debugging on the software side is the chip detected? There are apparently also 10 uF capacitors on the output calculated from the output impedance and the frequency at which the phase is degrees.

I forgot about this topic. This probably would not happen on the headphone output. Wow, this is indeed impressive. Here is a link to the problem: Updating the BIOS will fix audio for people running the generic driver which relies on BIOS tables, and updating the mainboard specific driver will undo the damage that the prior version of the driver might have done.

I have the same motherboard. These tables are very often incorrect, and are overridden by the Windows driver shipped by mainboard manufacturer or the chip supplier. Comparing the datasheets, it seems like the two chips use different flipped jack detection circuits: Any idea if this can be done with IDT sound-chips? All HDA chips should have very similar though not necessarily identical pinouts. The right side of Figure 19 is not part of the motherboard. They may be analog power pins that power the analog portion of the chip.

In contrast, the Realtek line of HD Audio codecs are generally well-supported. Within one jack group 4 jacks sharing one jack detection pinALC uses Tested both AC97 and HD settings and still no sound. I just made an order for 2 of these on eBay.

It shows DC decoupling capacitor and then a ferrite bead inductor and then yet some capacitors to the ground. Some sort of best case result with Etymotic HF5: I googled and couldnt find a straight answer to this one: Figure 18 in the datasheet http: Try setting the main output to headphone mode.

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? Note that while output is bit capable input is bit oddly, both are bit according to datasheet. I did a loopback with a y-splitter cable and AKG K attached. Are the jacks not detected at all, or is the wrong jack detected?

I kept and tested the stray resistor. Perhaps try testing the existing wiring first. Software side, Windows detects and installs the drivers. ErnestS on I have not rigorously tested whether all of the output ports work.
