'lsof /dev/dsp' should give you that info.
Try this if you want OSS (Open Sound System) software to behave nicely with
ALSA:
apt-get install alsa-oss
then run your old OSS software (ie. realplay) like so:
aoss realplay
This will allow ALSA to do the mixing on a multi-channel card. (You can
also get ALSA to do software mixing if your card needs it -- google for
"alsa dmix".)
