No sound played with alsasink plugin

[damoder mogilipaka]

Dear,

We tried playing raw PCM data and audiotestsrc in our target board, but there is no sound coming out.

We tried with the following commands, but no sound being played.

gst-launch-1.0 audiotestsrc ! alsasink

gst-launch-1.0 audiotestsrc ! audioconvert ! alsasink

gst-launch-1.0 audiotestsrc ! audioconvert ! autoaudiosink

gst-launch-1.0 audiotestsrc ! audioconvert ! alsasink device=hw:0,0

gst-launch-1.0 audiotestsrc ! audioconvert ! alsasink device=plughw:0,0

gst-launch-1.0 audiotestsrc ! audio/x-raw, rate=48000, channels=2, format=(string)S16LE, layout=interleaved ! alsasink

gst-launch-1.0 audiotestsrc ! audio/x-raw, rate=48000, channels=2, format=(string)S16LE, layout=interleaved ! alsasink device=hw:0,0

gst-launch-1.0 filesrc location=test.pcm ! audio/x-raw, rate=48000, channels=2, format=(string)S16LE, layout=interleaved ! alsasink

Whereas, the sound is being played with following command, on the same target board.

aplay -D hw:0,0 test.wav

The sound is being played with ffmpeg commands also.

What we are suspecting is that alsasink plugin is not working on our target board.

What could be the problem/issue for sound being not played on our target board with gstreamer commands ?

Please let me know the solution.

Thanks & Regards,

Damoder

What is your target board, what ALSA driver is being used? Also check
the debug output of alsasink with GST_DEBUG=2,alsa*:6
