wow, thank you so much. your post made me realize what was going on.
I was having sound problems when i was using pulseaudio a while ago, and i read on a thread to save something as .asoundrc.
I did, and left it there.
Now, i deleted it, and everything works fine. (facepalm)
Thanks for all the help!!
EDIT: False alarm, it only worked for a while, and now everything's the same.
here's the output for lsof | grep snd
