It has been recommended (I unfortuantely lost the mail header and don't
know who wrot ethis mail; thanks anyway) to check
http://blogs.sun.com/jg and also have a look into update_drv. I
modified the entry in /etc/minor_perm from "audio:* 0600 root sys" to
audio:* 0666 root sys
and ran "devfsadm -c audio". I also tried "update_drv" which just gave
me a list of options. "update_drv -v audio" gave me
-bash-3.00# update_drv -v audio
Failed to update audio.conf for driver.
and I can still not access /dev/audio when the app is run as a normal
user (it works when run as root).

2007-05-31 10:29:08.177 AudioPlayTest[26025] Error: open() returned -1;
errno 13
I am stuck! Any idea?
Thanks a lot!
Regards,
Andraes
