I've got a teensy 4 hooked up to the Rev D. Audio Adapter. Right now, when I plug it into a desktop computer via USB, it sounds great! (I mean, I'm still fiddling with the bitrate for the audio files, but...)
However, when I plug it into the wall with a USB connector the overwhelming hum and the raw power drowns everything else out. When I plug it into a MS Surface (the only laptop I have handy) the audio is way too faint to hear. Unless it's charging, in which case the hum takes over.
I also tried plugging it into a phone charger, that claimed to be giving it 5v / 2.4 A, and it was too faint to hear. My next though was to try jury-rigging some sort of 9v battery thing, but then I realized that a) that was probably a terrible idea, and b) I should just ask you.
What's the recommended power supply for playing audio from the teensy 4 / audio adapter? Ideally something involving batteries, so it's nice and portable?
Thanks!!
