I'm trying to setup system-wide pulseaudio for local-only users. I've
read about required pulse-access group but it seems that no checks are
performed by pulseaudio-0.9.13 (from FreeBSD ports) for user membership.
The server just says:
protocol-native.c: Denied access to client with invalid authorization
% paplay sample.wav
Connection failure: Access denied
% grep pulse-access /etc/group
The only way I found to make it work is to write in
load-module module-native-protocol-unix auth-anonymous=1
The server was tested as:
# pulseaudio --log-target=stderr --log-level=4 --daemonize=0 --system=1
Interesting info from the stderr log:
W: protocol-native.c: Authentication group configured, but not available on local system. Ignoring.
If I change the line in system.pa to
load-module module-native-protocol-unix auth-group=pulse-access
and start pulseaudio as showed above, it writes:
E: module-protocol-stub.c: Failed to parse module arguments
E: module.c: Failed to load module "module-native-protocol-unix" (argument: "auth-group=pulse-access"): initialization failed.
E: main.c: Module load failed.
E: main.c: Failed to initialize daemon.
Than I've looked into source files module-protocol-stub.c,
protocol-native.c and creds.h. The discovered data are:
1. "auth-group", "auth-group-enable" arguments for
module-native-protocol-unix are only available when "if
2. Checks for user membership are only done "#ifdef HAVE_CREDS".
3. HAVE_CREDS macro is undefined for FreeBSD because pulseaudio uses
Linux (-only?) ancillary message SCM_CREDENTIALS for authentication
in sockets communication.
Are my assumptions true?
Thanks in advance.
Sorry for my terrible English.
