Audio station pause often over WAN

[chu2001]

Hi all,
Since firmware 839 and up, the audio station in DS508 has not working correctly for me over wan. I have 10M/512K connection but when stream MP3 using audio station, it often pause for 5-10 seconds every 30 seconds or so. Play over LAN is ok without any pause. I know the connection is ok because I can stream video from my photo station with both sound and video working correctly. Look like the audio station is not buffer enough ahead that cause pause problem.
Is there anyway I can increase the buffer time for Audio station? Thank you very much for your help.
