Could you elaborate a bit on what you are trying to do? (there might be a better way without using 'su'. The behaviour you are getting is by design, so there is nothing really to fix. However, you can of course make the system behave the way you want: Either, assign your devices to the audio group and the same with your users. Or add systemd_pam to the su pam file. This will create a new session for you when you use su and should therefore adjust the ACLs accordingly. HTH, Tom
