Hi ,
i tested the site you given and plays good. No matter if i am 96% users reliable
It plays from within Firefox.
So try to install (or reinstall) Ubuntu-restricted-extras..
1)
Code:
sudo apt-get install ubuntu-restricted-extras
Also , try other stations , it seems not all stations play well.
2) Last thing , see if you have flash player installed correct.
Code:
apt-cache policy adobe-flashplugin flashplugin-installer
3) and as last resort , you can reinstall Firefox . You must delete hidden folder .mozilla too.
But you will lose any bookmark you have , so its wise to do a bookmarks backup fist.
If you want further assistance post back here.
Thanks
