Comment 13 for bug 83015

I have Dell Latitude D505, and a few days I have no sound. when I upgrade to feisty everything was fine for a few weeks,

I tried to change sound driver in sound preferences, but no sound i heard with all of them, when I play mp3 in xmms and in sound preferences change driver to OSS it gives me error that resource is busy

in device manager is sound card recognized correctly
in dmesg is no info about sound
