[SOLVED] pulsaudio won't start: Several permission errors

[faux]

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: Select all

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.
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!

It's not the HOWTO problem, it probably your config.

I also think so.

In random order:
make sure you are both in pulse-access and audio groups

It does not even work as root.

comment the line loading module-x11-publish

Okay, the output got shorter:

Code: Select all

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.

I think you are running either a different sound server or some program,
that already claimed soundcard, check that

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

and post useflags of your pulseaudio

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.

[John Klug]

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

Code: Select all

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: Select all
