Hello,

Yes, apparmour is installed.

No, I do not get any output through dmesg, or any log file in /var/log when I play sound as regular user.  However, when I play sound as root, the /var/log/auth.log gets messages, as one might expect.

this is certainly a puzzle

OK. is apparmour installed? Does "dmesg" show something when you try to ply sound as user?
