Try to configure pulse audio to use the alsa backend where HDMI sound device is used.Author: metind Time: 12/25/2018 16:22
When I try to play using vlc, i get this error msg. Also if i play same video as gst-launch-1.0 uridecodebin uri=.... ! rkximagesink, for 4K video there is no problem for video but cant get sound. So also i tried ;
pactl list short sinks and saw that ;
0 alsa_output.platform-hdmi-dp-sound.stereo-fallback module-alsa-card.c s16le 2ch 44100Hz suspended
1 alsa_output.platform-rt5640-dp-sound.stereo-fallback module-alsa-card.c s16le 2ch 44100Hz suspended
and i did pactl set-default-source 'alsa_output.platform-hdmi-dp-sound.stereo-fallback' .But nothing changed. Always sound comes from speaker (rt5640). How can i solve it and which player is the best for 4K video and oudio?

I'll find time to have a thorough check on video playing.Author: penguin Time: 1/5/2019 18:03
The problem is identified by the missing mpg123 gstreamer plugin in /opt/gstreamer.
