When the device nodes in /dev/snd/ are created dynamically (with udev), it's possible that their permissions are set by the udev rules and do not come from the directory. When you log in as mpd2, what are the permissions of the files in /dev/snd/? Do you get the expected result when doing "cat /dev/snd/pcmC0D0c"? (The expected result is "file descriptor in bad state".) > BIAMP SYSTEMS EMAIL NOTICE > The information contained in this email and any attachments is confidential and > may be subject to copyright or other intellectual property protection.
