me too... volume is not muted... manually setting volume flashvar does not work... reinstalling flash player and audio drivers does not work... there has got to be a bug somewhere either in the player or youtube...
Also, I might add that I built my own player in Flex and used it for about 6 months.. also playing youTube videos from my player... not once did I experience sound issues... I don't think it's YouTube's system problem ;)
wait wait.. this is stupid, I can't ask every single user our there having this issue to change their sound settings.. specially for users who don't even have windows..
But at least now we've narrowed down something here.. 48 khz causes a problem, with some thing in flash perhaps?
I don't think you have the fix, please don't post and kill this thread as if you do, we need JW to find a solution so that other OS's and Windows don't suffer from a sound resolution problem.. but at least he knows where to look
If I download one of the FLV files from Alltrailers.net (e.g. http://c2.stream.alltrailers.net/592/627.flv) and play it locally with any other player (like VLC) I still hear no sound. So that points towards the codec or source file.
when i check the trailer you mention, it doesnt contain any audio track at all, so no wonder it is silent... (the same applies to a few other that i checked from the site )
the adobe flash player is a browser plugin that enables browsers to display flash animation/movies and actionscript programs with the *.swf *filename extension...
the youtube and jw players are such .swf files containing actionscript - that happen to function as video players - able to display videos with the .flv filename extension and several other formats, in the case of the jw player, such as .mp3 and .mp4
just as the youtube player, the jw players are not installed on your machine, but embedded in the webpages that show them - and as such can not be uninstalled, as they never were (installed) - contrary to the adobe flash player browser plugin that execute them...
I'm having the same problem only a Mac. I figured I was just going deaf. The Adobe forums support for Flash did no good. Hmmmm what do I do? Updated Firefox to the latest ver.. Unistalled and reinstalled Flash (last ver. as of August 28, 09) tried it in Safari, Firefox and another browser. Messed with the volume controls in the system prefs and I have even tried repairing permissions. WTF!!!
