Sound as an ordinary user - how?

[Viktor Lakics <lakicsv@usa.net>]

Hi Debianers,

I cannot play any sound files as an ordinary user, while as root
everything works fine (MP3, wav, whatever).

I got the message :

** WARNING **: oss_open(): Failed to open audio device (/dev/dsp):
Permission denied 

Do I have to be a member of some special group (like dialup users)
to be able to play sound in debian? If not, how could I set up the
permissions for ordinary users for sound?

Thanks in advance. Viktor
