No sound after 1 second after AAC decode to usb sound card, but output to file seems OK

[Diaz Soho]

Hi all,

the pipe I used for verification:
1. gst-launch-0.10 -v
http://192.168.1.3:9000/disk/DLNA-PNAAC_ISO-OP01-FLAGS01700000/O0$1$8I2829.m4a!
qtdemux ! ffdec_aac ! audioconvert ! audio/x-raw-int,width=16 !
filesink
location=/var/tmp/usb/sda1/aac_test.pcm

2. gst-launch-0.10 -v
http://192.168.1.3:9000/disk/DLNA-PNAAC_ISO-OP01-FLAGS01700000/O0$1$8I2829.m4a!
qtdemux ! ffdec_aac ! audioconvert ! audio/x-raw-int,width=16 !
alsasink



In the pipe 1 , the output file /var/tmp/usb/sda1/aac_test.pcm can be
played normally.
In the pipe 2, the output from usb sound card can not be hear normally
after about 1 seconds.

Does anyone have any idea about the issue?
