RE: Power Supply for my sound card

Ok, that makes more sense now.

This drawing from the MT1117 datasheet showw the different circuits for the fixed versus the adjustable.





You need to find the voltage-setting resistors (R1 & R2 on this drawing) on your soundcard board. They should be very close to where the MT1117 was. Remove the resistor on the soundcard that corresponds to R2 on the drawing. Then attach the ground wire from the SuperTeddyReg to the ground pad where that resistor was.

It won't hurt to leave the resistor that corresponds to R1 on the soundcard. And where you connected the 3.3v wire from the SuperTeddyReg should still be ok.

You should not need the connection you made to the PCI finger.

Try this and let us know how it works.

P.S. I'm glad you caught this. I was scratching my head trying to see what you did wrong and couldn't find anything!
