I kind of wonder if you don't have a flakey display. I did not add the terminating R and everything has always worked fine on the display. After I quit using the 3" jumper cables to the audio card and stacked the modules, the audio worked correctly. My display is on a set of 6" jumpers and has been stable from day one. Though currently the display isn't connected since I am experimenting with various modules in the teensy. Regards Paul WB8TSL
