the jack thread isn't really working at that moment. It don't need to play
data. last weekend i have found the verbose flag and it gave me the following
infomation

----------------------------------- schnipp

somewhere i have read, that this disconnect would be amount, if the CPU load
is to high. after blocking the loader thread to update the GUI, its getting
better.
looking/locking further c~
