The audio is aac format. The audio frames(packets) are frequently sent to the aac decoder & alsasink to play out. Unfortunately only the begining frames can be played out and then nothing is played out. <BR>If we save those audio frames into a file, the aac decoder&alsasink can be successfully played out. It means the audio frames are ok. <BR>Could anyone tell me what's the difference for alsasink to process audio packets and files? How to fix the above issue? thank you very much!<BR> <BR>Best Regards!<BR>Shenhong WANG<BR><BR> <HR> Connect to the next generation of MSN Messenger  <A href="http://imagine-msn.com/messenger/launch80/default.aspx?locale=en-us&source=wlmailtagline" target=_new>Get it now! </A></BODY></HTML>
