Sorry, but it *didn't* work before. 

By default the access mode of the dmix SHM is 0600. i.e. only a single
user ID may access the sound card at a time.

If you want to open up dmix to multiple users at the same time you
need to change it to 0666 or so, which is a security hole and needs
some non-trivial reconfiguration.

The reconfiguration necessary to open up PA to other users is a lot
simpler to do. Just copy a cookie file around.

I didn't dismiss your use case at all. All I told you is that the kind
of setup you envision required non-trivial reconfiguration before, and
it requires reconfiguration now. So, calling this is a regression is
