Dear All,
When I use this img, i cant get sound from hdmi part. I mean the sound comes from speaker output of board but cant get from tv speaker. So how can i change it as default hdmi output. I checked at ubuntu and couldnt chnaged it.
Try to configure pulse audio to use the alsa backend where HDMI sound device is used.
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.
The problem is identified by the missing mpg123 gstreamer plugin in /opt/gstreamer.
To fix this, reference
http://bbs.t-firefly.com/forum.php?mod=viewthread&tid=2490&page=1&extra=#pid11605
to get the uptodate gstreamer debs installed.
Then you can use the /usr/local/bin/play-4k.sh to play 4k video with sound.
