Complete newbie here. Never soldered, used a teensy, and never used an programming other than people's pre-made R scripts. I am using a Teensy 4.0 with some stacking female headers to connect to audio shield rev d. If I put an ad card it won't work. I tried using the "beep" example and it works. If I the hardware-->SD card example it says "SD card is unusable" or SD card intialization failed even when I put i put it into the audio shield. I don't know if I fried my board. Is it just a piss poor job of soldering. I checked all connections with a multimeter. Any guidance would be greatly appreciated. Thanks in advance.
