Comment:
Because there needs to be a new session such that pam picks up and sets all limits, that's why it's important to re-login after adding a user to the audio group.
Have you manually changed `memlock` within `/etc/security/*` perhaps somewhere?
Memlock should be set to unlimited for all audio group members.
