Audio issue #15

Closed williambout closed 9 years ago

williambout commented 9 years ago

I have a speaker connected to my A+. I have set the audio output to the 3.5mm jack. Launching python examples causes sound glitches. Is it normal ?

Gadgetoid commented 9 years ago

Yes, unfortunately it's normal. The extremely bonkers process used to create the signal required to drive Unicorn HAT involves using the PWM hardware that's crucial to analog audio, so both can't be used at the same time.

That's what I thought. Thank you for confirmation.
