Need some help... Pi act-led flickering and speaker noise

Post by rob » Thu Aug 18, 2016 1:39 pm

I've almost finished my GB Zero build but have a strange issue. Before I assemble the GB I powered it up for a final test. But now the Pi's act led is flickering. At the same time the speaker is making noise. Is there somebody who can point me to the right direction?

Here's a video where I power on the GBZ; https://youtu.be/Zqu_xV6Cq58

Could you provide some more info on how you wired your components together?
Also, the flickering should be normal. That's just an indication that the pi is working. Does the screen and everything else turn on normally?

I observe a similar noise in my build that appears to be coupled to the LED as well as to what is shown on the screen. I powered my amp directly from the powerboost and that's probably the reason why the speaker picks up signals from the other components.
