How do you make mono audio track playback in stereo in Ubuntu?

Every once in a while I'll come across a video that I want to watch (whether it be youtube or otherwise), and the sound, for whatever reason, will be only coming out one speaker. It's not a problem with my hardware, or any kind of configuration; it's because whoever encoded the video, messed up the audio. If I used speakers this wouldn't be a problem, but 100% of my listening is done with headphones. This makes for a very annoying experience. You'd think something like this hardly ever happens, but it seems I come across this more than most people, and it;s really annoying.

"Not exactly a solution for you, but the 'ecasound' package will, at the command line, fake stereo from a mono sound file. That is, it will create a second sound channel on a .wav file which is in mono.

Sometimes I save an internet video to disk and then turn it into an MP3. If it's mono this fixes it.

I understand that you want something that will fix a streaming video file while it is playing: I honestly don't know of a practical way of doing that. I suppose you could put the Jack package in your sound queue and add some sort of real-time filter, but, honestly, I think the pain of trying to get that to work wouldn't be worth it. Sorry."

You can do this if you have JACK/QjackCtl installed. In QjackCtl's Connections dialogue, you would connect the front-left channel to system's playback_1 and playback_2. All the documentation you need can be found at http://jackaudiodotorg

This seems late, howver, for annoying youtube videos or other sites. The SoundFixer extension on Firefox works like a charm.
