When I insert a block that read the microphone on an Adafruit Circuit Playground Bluefruit the program get stack. Let’s look for example at this program:

The leds are suppose to blink green and purple but they are not. If I remove the “on loud sound” block from the program then the leds blink green and purple.

I got exactly the same error and tried to debug it, but building a full pxt/codal build-chain seams incredible hard. The Adafruit-Vargrant-Box is broken:

- \_github.com/adafruit/Adafruit-PXT-Setup/blob/master/Vagrantfile

For this error, I’ve added a bug at “pxt-maker”:

- [https://github.com/microsoft/pxt-maker/issues/331](https://github.com/microsoft/pxt-maker/issues/331)

As well as an entry at the adafruit forums, but I have no idea if any solid support for “CPb” for a MakeCode implementation is planned from their side:

- \_forums.adafruit.com/viewtopic.php?f=58&t=173788&p=847535&hilit=bluefruit+makecode#p847535

And on the Discord-Channel I didn’t get a response (yet) either:

- [https://discord.com/channels/327254708534116352/448961493590081568](https://discord.com/channels/327254708534116352/448961493590081568)

So, if anyone has an idea:

a) How to debug this thing?  
b) How to find support for this topic?

You would be more than welcome.
