It's a bit of a fuzzy problem and it is not clear to me whether there is a real driver bug somewhere, or if it is really a hardware issue or something like that. But if you want to get this fixed then you first need to upgrade to a kernel >= 2.6.22, and then install the bleeding edge drivers on top (see http://www.ivtvdriver.org/index.php/Download#Bleeding_Edge_driver) If you can reproduce it with that setup, and in particular if you can do something as simple as 'cat /dev/video0 >foo.mpg' and the sound disappears after X minutes, then please report back. A setup like that will enable me to trace the problem.
