I moved from 11.0 to 12.2 and have discovered that the /dev files related to sound are not rw access for non-root. So I placed a command "chmod a+rw /dev/audio /dev/dsp /dev/mixer" for these files in rc.M.

This works *somewhat*. (for non-root) The mixer doesn't have all options, and sound won't play for UTUBE on the browser which I think is flash-player. I have installed flash-player as root. When it runs as a user, seems to play but no sound. When ran as root works fine.

Are there other files in dev besides the three I have tweeked? Or is the problem with the installation of the flash player?

Try adding the regular users to the audio group?

I've never bothered with additional groups before. That was the quick answer allright, thanks!
