Gstreamer master - Could not open audio device for playback
Hi gstreamer team,
I've just built the source from gstreamer master on Ubuntu 20.04 and want to run a simple test to verify the build. The pipeline "gst-launch-1.0 videotestsrc ! autovideosink" to play the sample video is working fine. But the pipeline to play the sample audio is not working
[gst-master] convedia@Ubuntu1:~/gst-build$ gst-launch-1.0 audiotestsrc ! autoaudiosink Setting pipeline to PAUSED ... Pipeline is PREROLLING ... WARNING: from element /GstPipeline:pipeline0/GstAutoAudioSink:autoaudiosink0: Could not open audio device for playback. Additional debug info: ../subprojects/gst-plugins-good/sys/oss4/oss4-sink.c(513): gst_oss4_sink_open (): /GstOss4Sink:autoaudiosink0-actual-sink-oss4: system error: No such file or directory Pipeline is PREROLLED ... Setting pipeline to PLAYING ... New clock: GstSystemClock
If I exit from the development environment and run the same pipeline on the host (which have official gstreamer 1.16.2 release installed), it works fine. Can anyone help?
