RRRRRR!!!! Blaaarrrrgghhh!!! No way. My process list is empty of any sound applications. $#@$ >:( Maybe some problem with my modules snd. But... what problem?!! Thanks for your help. If this error is a "lock" device, so... maybe problem with load my modules. But I can't load manually the default module for VIA82xxx of Slackware. After installation the Alsa-driver the only module can be loaded is the snd-via82xx(the module of Alsa). For this things I believe now In one error in my system modules. Thanks!
