Hi!
I'm playing around for a couple of days to get PulseAudio running, but I'm still at point zero: It won't start:

Code:
manuel-desktop lib # pulseaudio --system
W: pid.c: Stale PID file, overwriting.
W: main.c: setrlimit(RLIMIT_NICE, (31, 31)) failed: Operation not permitted
W: main.c: setrlimit(RLIMIT_RTPRIO, (9, 9)) failed: Operation not permitted
E: shm.c: shm_open() failed: Permission denied
W: core.c: failed to allocate shared memory pool. Falling back to a normal memory pool.
E: alsa-util.c: Error opening PCM device hw:0: Device or resource busy
E: module.c: Failed to load  module "module-alsa-sink" (argument: "device_id=0 sink_name=alsa_output.pci_8086_2668_alsa_playback_0"): initialization failed.
ALSA lib control.c:909:(snd_ctl_open_noupdate) Invalid CTL front:0
Xlib: connection to ":0.0" refused by server
Xlib: No protocol specified

E: x11wrap.c: XOpenDisplay() failed
E: module.c: Failed to load  module "module-x11-publish" (argument: ""): initialization failed.
E: main.c: Module load failed.
E: main.c: failed to initialize daemon.


I've configured nothing, still no HOWTO says, that is is required to configure anything. I've read the Gentoo-Wiki entry on PulseAudio and I've read some official PulseAudio wiki entry, but I'm unable to start it. :oops:
Can anyone recommend a good HOWTO to me?

It's not the HOWTO problem, it probably your config.
In random order:
make sure you are both in pulse-access and audio groups
comment the line loading module-x11-publish
I think you are running either a different sound server or some program,
that already claimed soundcard, check that
and post useflags of your pulseaudio

Thank's for the response!

I also think so. ;)

It does not even work as root.

Okay, the output got shorter:
Code:
manuel-desktop pulse # pulseaudio --system
W: main.c: setrlimit(RLIMIT_NICE, (31, 31)) failed: Operation not permitted
W: main.c: setrlimit(RLIMIT_RTPRIO, (9, 9)) failed: Operation not permitted
E: shm.c: shm_open() failed: Permission denied
W: core.c: failed to allocate shared memory pool. Falling back to a normal memory pool.

No, there is no other sound server. How do I check this, either?

X alsa avahi dbus hal tcpd

Okay, now the daemon starts (ignoring the shm_open error). Thanks!

But: Every app which uses PulseAudio logs: E: shm.c: shm_open() failed: Permission denied. :S

Edit: Adding shm /dev/shm tmpfs nodev,nosuid,noexec 0 0 to /etc/fstab helped. I knew this line has any function. ;)

Thank's for you help. :)

shm_open can be fixed by adding a line to /etc/fstab:

Code:
none                    /dev/shm        tmpfs           nodev,nosuid,noexec  0 0


Now mount /dev/shm

I am working on the same problem. I need to figure out how to get it to work with ALSA:iec958, the way MythTV does. It sends output to analog, but I want digital.

I get:
Code:
