Would you mind providing a log file? you could start SD with -l 5 -L

capture a log and send it to me

this is strange since spelling is not supported in pico plugin at the  
moment, it should be something inside pico engine.

this is due to the fact that audio buffer is not cleaned, I'll provide a  
fix for it.

It could be probably fixed, but I do not see much activity on Pico engine  
development.
