thank you trevorh for you prompt reply... well I fixed and made some order on yum, now yum status should be ok, I removed some package which was blocking my upgrade and then, finally, I made it.

I've been running Ubuntu Server 13.04 for about six months, using an HDMI connection from my video card (NVidia) to a TV. Originally I had some issues with sound not working, but at the time an upgrade to a new kernel fixed it (I can't remember the version, though).
I upgraded to 13.10 a couple of weeks ago and my sound broke again.
