Recently did a system recovery on my One, installed the usual stuff on it(vlc, firefox3.6, gimp, thunderbird) Everything looked great, then installed the latest flash player 10.0.42.34. Well not long after that, like an hour, I was on youtube. Played couple of videos and were working fine, then open a new one and no sound. Restarted firefox and nothing. Tried an mp3 file and still no sound. Restarted the computer and everything was fine. Played and avi movie and was still ok. So thought nothing of it. Youtube works but still once in a while I just lose all volume. The video plays, mp3 seems to be playing but no sound and have to restart the system. I think it has something to do with Adobe flash player, because it always happens while in youtube. Anyone else have this problem? Could it be my firefox add ons?(fasterfoxlite, flashblock) Thanks in advance for any help.
