Underflow in pipeline_bt_source example

Thanks

Re: MP3_DECODER: reduce buffer size

I know that my board doesn't meet the requirements, for the use I was planning the actual limit is memory size for buffer.

Starting from the a2dp_source example sketch I've succesfully connected the headset and played the random audio. Then with t...
