Rhytmbox unable to open /dev/dsp

[antonio montagnani]

I upgraded Rhytmbox to 0.6.7.
I can play music as root but when I log as any user I get no music and a 
message :
osscommon: unable to open /dev/dsp (in use?)

What does it mean and how can I make it play again (previous releases 
seemed to be o.k.)???

Tnx
