[Nix-dev] Pulseaudio broken in 14.12: Daemon already running

[Kirill Elagin]

As Benno said this means that most likely something is wrong with your
session and you don’t get access to audio devices.
What’s strange is that 14.12 uses xorg-server-1.16-* and this should run as
user by default and as a result should crash with insufficient permissions
to access video devices unless you do something special to start it as root.

Do you use a desktop manager or start your X session manually? The
important thing is to make sure that your X server is running on _the same
virtual terminal_ your logind session was opened on, otherwise you won’t
get permissions to access hardware. Desktop managers take care of this and
recent versions of `startx` (starting from xinit-1.3.4 IIRC) also do.
`loginctl show-session <session-id> -p VTNr` tells you what logind thinks
is your session’s terminal. I believe that the default of X is still to
choose the first available terminal, so you have to explicitly pass it
`vt<your-session-terminal-number>` (`startx` does exactly this).
