https://stackoverflow.com/questions/67205270/gstreamer-appsrc-doesnt-play-audio-to-autoaudiosink
When I look at the DOT file everything is linked up and looks like it should be working, but there is no audio! The only warning I get is: WARN audio-resampler audio-resampler.c:274:convert_taps_gint16_c: can't find exact taps. EDIT: I tested this on a Mac using autoaudiosink and it worked. I did the same pipeline on Linux (raspberry pi 4) and ...

Regarding the configuration of the appsrc and appsink elements: gst_audio_info ...
Gstreamer pipeline to stream video frames and audio – Ask ...
https://askpythonquestions.com/2021/11/04/gstreamer-pipeline-to-stream-video-frames-and-audio/
The launch string that I am currently using works, but the audio in the RTSP stream is ahead of the video frames. I’ve noticed that upon starting the stream, the audio runs smoothly but the video frames stutter initially, which could be why the frames are falling behind. I’m very new to gstreamer so any help is appreciated.

https://gstreamer.freedesktop.org/data/doc/gstreamer/head/qt-gstreamer/html/examples_2appsink-src_2main_8cpp-example.html
In this example, we have two pipelines, one pipeline that gets data from a file, decodes the audio stream and sends the audio buffers to appsink, and a second pipeline that gets data from appsrc and pushes them to an audio sink. Appsink from the first pipeline is linked with appsrc from the second pipeline in our code, by listening to appsink's newBuffer () signal, …
