Does your system use devfs? I can't remember if Redhat 7.2 uses this, but with devfs device permissions are allocated to users on the fly as you describe.
In this case you can force permissions in /etc/devfsd.conf. Such a fix is mentioned in the ALSA "INSTALL" file included with the ALSA drivers. Here's the pertinent section for setting up sound device permissions: DEVFS support ============= The ALSA driver fully supports the devfs extension. You should add lines below to your devfsd.conf file: LOOKUP snd MODLOAD ACTION snd REGISTER ^sound/.* PERMISSIONS root.audio 660 REGISTER ^snd/.* PERMISSIONS root.audio 660 Warning: These lines assume that you have the audio group in your system. Otherwise replace audio word with another group name (root for example).
