No sound (/dev/dsp) in new X session
My sound work OK on my Mandrake v10 desktop but, when I start a new KDesktop (a second X session), I got an error message telling me that the device /dev/dsp is unavailable (no right...). Then, the sound doesn't work in that session but is always working in the first one...
What do I need to have my sound working in all my sessions?!?
Thanks for any help!
