Sound doesn't work (/dev/dsp: Device or resource busy)

Many of my sound-producing applications refused to produce sound at some moment. I cannot remember what i did that could cause it, perhaps installed kdemod 4.1.
I usually get this error:

/dev/dsp: Device or resource busy

but some applications (mplayer, lastfm for example) work correctly. I have no supicious apps that could eventually lock /dev/dsp running.

$ grep DAEMONS /etc/rc.conf
DAEMONS=(syslog-ng network netfs crond atd sshd postgresql alsa kdm) # with or without esd the same problem

any hints?
