I bought a phatbeat at a raspberry jam.
Iniitially it seemed OK : with no speakers connected the speakertest pulsed the bargraphs. But there was also an oddity : one of the bargraph LEDs (+3dB, right) was always on, dimly green. It flickered a bit during boot and shutdown.
Then I connected speakers : when I tried speakertest, the Pi rebooted.
I’m using an Asus 2A power supply but I did try changing the USB supply cable. This helped : the LED no longer flickers and the Pi doesn’t reboot when I run speakertest (which seems to be fine).
But I still have 2 problems : the dim green LED is still on (it works fine in the various LED tests) and there’s a crunch sound every time the speakers are enabled, eg when an application starts to use them.
Are these problems normal, or is my phatbeat faulty ?
