alsasink not working with playbin

[psiva87]

Hi,
I'm seeing below alsasink issue when playing using playbin. But same is not observed when manually constructed the pipeline using gst-launch of individual elements. "gst-launch-1.0 audiotestsrc ! alsasink" also works. Gstreamer version I use is 1.10.4.

# gst-launch-1.0 playbin uri=http://<x.x.x.x>/test.mp4
Setting pipeline to PAUSED ...
Pipeline is PREROLLING ...
Got context from element 'sink': gst.gl.GLDisplay=context, gst.gl.GLDisplay=(GstGLDisplay)"\(GstGLDisplayWayland\)\ gldisplaywayland0";

Do you have anything alsa on your platform that actually works ? Looks
like a system issue, not a GStreamer issue.

Hi Nicolas,
If I play the same using manual pipeline(gst-launch of individual elements), alsasink is playing fine. Even this issue is observed we migrated to 4.9 from 4.4.

If you can reproduce in gst-launch, can you run with the -v option, for
both working and not-working cases. I suspect that the audio format in
your manual test isn't the same, and that triggers a driver issue. The
verbose mode should trace the caps on each elements.

Nicolas,
I'm using same file for the both working & non working cases i.e manually constructed pipeline is working but playbin pipeline is not working with same stream.

Try to use autoaudiosink to check the results. 

Use the audiosink option in playbin. 

Both will help you to check the autorecognition of your system.

Yes, I tried with audio-sink=autoaudiosink also.

Sure, but you are the only one reproducing an issue here. I'm trying to
provide you the tools to try and find out why. Maybe playbin didn't
pick the same elements as you did ?

Nicolas,
I checked the pipeline diagram of
                                                                     





and I seem to have used similar pipeline manually except queue & tee connecters.

Try audio-sink=alsasink

The quality of this image is way to low, I am sorry but I cannot help
you with that.

Finally the issue is with alsa driver only accepting the certain PCM samples(S16LE format). Thanks for the help anyway :-)
