It took me long to figure out that changes of sound ownership are due to pam_console and have nothing to do with devfsd. Maybe you should add a comment telling so to devfsd.conf where most people look in the first place. Perferably to every section of pam-managed devices, especially to sound. Maybe some comment on dev-state would help someone. bug#27857 and bug#29463 had similar problem. Also note bug#31877 on pam vs. dev-state and the future of both. Reproducible: Always Steps to Reproduce:
added a note to the devfsd conf file
