C1-3 should be 100nF, R1-3 should be 0 Ohm jumpers (or wire if you prefer). R6-8 should be 75 Ohm. R4/5 and C4 should be unpopulated, and instead, JP1 should be closed with solder.
For audio, you should install the switch (or bridge horizontally between the center holes and the holes closest to the edge), and then R9/10 should be 470 Ohm and R11 should be 20K.
