Hello,
I am trying to play a video using nvgstplayer-1.0 through the hdmi cable, the video is working but no audio. Here is my pipeline:

nvgstplayer-1.0 -i test.mp4 --loop-forever --svs=nvoverlaysink --sas=alsasink device=plughw:0,3

Any suggestions ?

Here is the output:

Note I have the UI disabled using:

sudo systemctl set-default multi-user.target

But the video is working just fine, no audio only.

Hi,
Please make sure the audio device name is correct. May also try gst-launch-1.0 command:
Can nvgstplayer play video without X11 environment? - #12 by DaneLLL
