Your issue is very similar with the issue I even met. I think it is due
to gstbaseaudiosink/gstaudiosink, it will drop the packets by
gstringbuffer when read rate is bigger than write rate in ringbuffer,
please see gstringbuffer.c gst_ring_buffer_commit_full ().
For the rootcause, I think maybe the alsasink audiodevice buffer is too
big or your aac decoder is too slow.

Subject: [gst-embedded] Question on gst_plugin alsasink
Now we are using alsasink to play audio on Marvell PXA310 board. 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.
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.
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!
