Hello to all of you.

I have a fresh install of Ubuntu on Lenovo thinkpad edge 13'' machine. The install went fine but youtube video (and presumably other flash content as well) was playing too fast. Somewhere in this forum, I have read that I should change the output device so I tried, and now there is no output at all.

Since, I don't have an hdmi capable machine, I don't know if the hdmi output work. But I can tell for sure that neither does the audio jack work, nor does the built in speakers.

How can I fix this? Also, how can I fix the fast audio problem?
