pinoutreverse-engineeringschematics
I have been blowing through bandwidth trying to find a pinout diagram of an old STK4192II stereo amp IC but all I can find are reference design schematics, while these will work I guess I want to use this as learning project on the effects of caps and resistors on sound while also making a 5.1 ch amp for my computer (the computer will be the Dolby processor).
So has anyone come across that? Or does anyone have tips on reverse engineering the pinouts (is that even practical?)
I managed to completely reverse the pins of this module:
Considering your first picture above, being the rightmost pin the number 1 (near the white dot), I've got, from right to left:
Update: I confirm it works finally as described above. I'm using tmk firmware and tried on teensy2.0 and pro micro.
Figure 1. The near pin is obviously connected to the outer ring of the socket. This forms a shield for the signal pin going through the centre to the pin at the rear of the socket. Figure 2. The plug showing the signal pin (centre) and the shield / ground (outer).
Connect ground to the shield pin (the near one in the photo).

After searching much longer than I expected to search for this, I have come to the conclusion that this does not exist. You could easily reverse engineer it by using the reference design schematics, specifically the Sample Application Circuit diagram and the table of description of external components diagram. You may need to infer some names to put along with it but it would be helpful nonetheless.
There seems to be a nice opportunity for you here then if you would be willing to make a pinout diagram of it. If you did that and then posted your project online, you would recieve all the traffic relating to people looking for the exact same thing.
