Hi everyone. I was having the same problem when trying to play a movie with mplayer. Reading in some forums, I came across a guy called \"jebba\" who guessed that maybe there was another process blocking the resource (as the error says :-P). If one wants to know which process is blocking alsa, one only needs to execute the command \"lsop | grep snd\" (without quotes). This lsop command lists all the open files (including the files that correspond to the devices being used). In my case I had KTorrent running and apparently it had blocked my sound card. I killed KTorrent, then I executed mplayer and it worked immediately. The URI where I found this info is http://forums.blagblagblag.org/viewtopic.php?p=24006&sid=2c862e0a52d8c3c03640e6197cf13e75
Thanks again to Jebba for the hints!
