double reset to put CPB into bootloader then copy uf2 file to upgrade its firmware. I don't think CPB support the std way makecode reset board to bootloader.
The resetting works fine.
The sound doesn't work well after the first run. Unpower / repower doesn't work either.
why do you think it is bootloader issue ? Can you try to upload with a simple blinky example with correct board selected from one of our arduino sketch to see if that works out.
Uploading works fine, it is only the audio behaviour with MakeCode. So if the bootloader has no audio code, your are right, this may be some weird startup / init behaviour, but within the Programm code, not the loader.
Btw: Updating the bootloader was very tedious (Arduino IDE & DFU setting required) compared to the SAMD21 boards, where just dropping a new UF2 file to update the bootloader was enough.
closed since this is not bootloader issue

We have done adding the uf2 selfupdate to this bootloader, but haven't got time to release it yet.
Great to hear about the self-update.
=> Regarding the Audio: Maybe there is the PIN D11 (Power Saving on Audio) disable, is this touched during the booting?
Describe the bug A programm MakeCode with sound works only after first start
Set up (please complete the following information)

Expected behavior I didn't expect "the sounds of silence" ;-), but beeps again
