Sounds on Linux mint Firefox

Question

I have Linux mint Helena, Firefox 3.6.10, and flash plug-in non-free 10.1.85.3Ubuntu0.9.10.1. I watched some videos in YouTube and everything was fine. Today I watched some videos and always the same thing: I can watch the video couple of seconds and the sound disappears suddenly. What might cause such a strange behavior?

I have no caches in my home folder as far as I remember.

Answer 1

Can you give some more informations like the output of: lspci | grep -i Audio and run this command when the sound disappeared and post the output: tail -f /var/log/messages

You can also reset your alsa confguration or clearup some configuration/temporary/cache files in your home folder
