Thanks Erik, this is great news. Finally an inexpensive sound solution for the TCB!
For those wondering, the adapter cable is not difficult to make if you are able to solder. In addition to the cable that is included with the Taigen sound card, you will need a standard servo cable. The TCB includes three servo cables intended to be used with a Benedini sound card, so you can just use one of those. You have to graft the Taigen cable to the servo cable as shown in the instructions that Erik linked to (I'm attaching the picture here also). The +5v signal from the TCB (middle pin on the servo connector) will actually need to be attached to two pins on the Taigen card. If you are familiar with soldering and splicing wires with a bit of heatshrink, the job will take you all of five minutes.
NOTE: The wire colors shown in the diagram will not match the wire colors of the cables you receive. Just be sure you connect them in the correct order and ignore the colors. The colors in the diagram are traditional colors for representing the purpose of each wire (ground, power, signal) but the colors that are used in China make no sense!
