This is regulated in /etc/logindevperm:
#
# console       mode    devices

/dev/vt/console_user    0600    /dev/mouse:/dev/kbd
/dev/vt/console_user    0600    /dev/sound/*            # audio devices
/dev/vt/console_user    0666    /dev/fbs/*              # frame buffers
/dev/vt/console_user    0600    /dev/dri/*              # dri devices

You can try to change the mode of /dev/sound/* to 666.
