Hi there. I had just setup a speaker pHat and installed the software / ran the setup. Upon playing something like an mp3 file, I can see that the first LED of the vumeter doesn’t light up. The others do, however. Might this be something I soldered wrong? I see the same thing using a pizero where I soldered the headers myself and a pi3 where the solders came pre-installed. Using the latest raspbian.9.1 stretch lite.
