I am trying out the Software N DAC option based on the NPN 2N 3904 transistor.
When doing it according to the github page instructions, the esp8266 crashes with a stacktrace - see details at this github issue :
https://github.com/earlephilhower/ESP82 ... /issues/42Any ideas why this is not working? There is a second issue reporting the same problem also!

It's a very bad connection. There is no resistor at the base of the transistor (around 270ohms) and the speaker should have a higher impedance.
The esp8266 output is essentially shorted to ground and the speaker may also overload the USB source.

Hi,
Are you saying I need a 270 ohm resistor on base?
I am powering the speaker from an external 5v supply, not usb.
