[SOLVED] lost sound after installing lightspark

view story

http://ubuntuforums.org – I was trying out Lightspark flash player to see how it worked on ppc. I uninstalled the Gnash browser plugin, installed lightspark with all the packages that came with it in synaptic. Lightspark didn`t work at all, not even detected in browser, so I uninstalled and reinstalled Gnash browser plugin. Ghash works, but I lost all sound, and I think Gnash graphics even got a bit slower. I have rebooted, opened alsamixer and checked settings, everything looks fine, still no sound when playing videos in browser or from hard drive. Any idea how to go about it? ...will never try lighspark again (Hardware)
