I’ve created a neat little baby monitor with a couple of Unicorn Phats running to produce some light shows.
I know that these use PWM, so I can’t reliably use the analog audio out.
I’ve connected a Bluetooth speaker which works pretty well for sound. However it doesn’t reliably connect and always takes about half a second to wake up when audio starts.
I was wondering if I could use a USB Speaker? Or will this still involve pwm?
There have been similar questions asked which suggest a USB sound card might work, but I’m not sure if USB speakers are effectively a USB sound card + speakers, or if they work in some other way.
