Gstreamer playback is discontinuous with APPE

Z.X

Hi Champions,

My customer use gstreamer to play music, the sound card is TI APPE pcmdsp0, the stream is discontinuous, for example, play 1s, then it skip to the 10s directly, but the Aplay works well, do you have idea to debug it?

Hi Pooja,

Please find my gstreamer pipeline:

gst-launch-1.0 filesrc location=/home/zhan/test.wav ! wavparse ! alsasink device="pcmdsp0"

The alsasink device is TI APPE pcmdsp0. If we don't use pcmdsp0, and use default alsa device, the gstreamer works well. But aplay works well with the pcmdsp0 deivce, does it related to the gstreamer buffer configuration or something else.
