ALSA problem sa user nalogom

Pozdrav
imam jedan problem sa ALSA-om. Naime kao root mogu da odaberem u Control centru pod Sound & Multimedia -> Sound system -> Sound I/O -> Sound I/O metod: Advanced Linux Sound Architecture (umjesto Autodetect kako je na pocetku namjesteno) dok ako sam ulogovan kao user to ne mogu nego mi javlja gresku:
Error while initializing the sound driver:
device: default can't be opened for playback (Permission denied)
koristim Slack 9.1
Sta treba da uradim da bi ovo dihtovalo?

Potpis

Proveri prava pristupa na /dev/dsp, /dev/mixer, itd. I setuj da user može da piše u njih.

# chmod a+rw /dev/dsp /dev/mixer /dev/sequencer /dev/midi

Potpis

int rand(void);

Those who do not understand Unix are condemned to reinvent it, poorly.
