cc2564 aud sink sample application (a2dp) stops streaming after 270ms

Other Parts Discussed in Thread: CC2564

i have ported the bluetopia library to a different mcu and it is working with the ibeacon demo. now i am trying to get the aud demo to work.

my current problem is that when i play music using pandora on my android phone the music stops after 270ms. the phone acts like it is playing but the time and progress bar do not advance. 

i am attaching a few files to help explain what is happening

console uart log.txt    --- this is the user interface for the project. this file was not captured at the same time as the rest and is only included as a representation of the problem. i have included a few extra debug messages (the problem is the same with the messages removed)

btsnoop_hci.txt         --- this is a "bluetooth hci snoop log" captured by enabling the corresponding setting under developer options on my android phone. the log can be viewed in great detail from the phones perspective useing wireshark (https://www.wireshark.org/)

cc2564 dbg log.lgr   --- this is the log file from the ti logger tool connected to the debug pin of the cc2564

2 scope captures      ---the traces are listed from top to bottom as follows SDO, SCK, WS, I2S FIFO interrupt (fifo not full int, causes the mcu to write another 2 bytes to the fifo)

all files are in this zip     logs and scope captures.zip
