After using sudo board-config.sh to update my pcDuino v3B various things stopped working and I have written about some of them in the previous posts. One ting I did not check before the upgrade though, was whether I had sound in my browser and things like smplayer and vlc. XBMC worked and for my original purpose that was all I was interested in.
But the more I got involved in this magic little computer, the more I wanted to try other things. And during that process I discovered the ONLY thing that had sound was XBMC. So I did a little snooping. And found a simple solution - for me at least.
Now at the time i didn't write down everything I did. It was after midnight and I was exhausted. But I know I did:
sudo apt-get install pavucontrol
I can;t remember if that installed all the other pulse audio stuff or if i had to also do:
sudo apt-get install pulseaudio
But if you have this problem, try the first. If it still doesn;t allow you to set up audio, try the second as well.
After I did this i could adjust sound settings from the volume icon on the panel. Then I had ausio output in everything inclusing YouTube videos!
