Hi,

We are playing a video on Mini PC without speakers in Linux. We encountered a strange issue that the video player hangs, but if we connect a headphone to the audio output the video starts playing. It seems like a gstreamer/linux audio issue and not a Cinder one, though.  
Has anyone encountered something like this before? Do you have any suggestions to fix this?

Hey Gabor,

I vaguely remember something similar happening on a setup I had years ago although I dont remember the particular details of said setup anymore - If I m not mistaken, somehow the default audio output, systemwide, was being set to be the GPU because of the HDMI connection present so I remember changing the default audio output through `pavucontrol` in order to overcome this issue.

Maybe you can check what available audio outputs you get through `pavucontrol` and what is currently being set and try to change that to see if it helps.

HTH,  
Petros

Thanks Petros. Your suggestion worked.
