Hi Jess, Not sure what you want to achieve, but normally you should create mem player port for each audio. Last few bytes replayed sounds like length inconsistency among audio's put in the buffer. Other possibility is PJMEDIA_MEM_NO_LOOP option is not set when creating memplayer. Regards, nanang 2008/6/25 vopjessie <jessievop at hotmail.com>: > Hi Nanang, thanks for the message again.
