MPD fails at boot time

tehabe · 2008-12-23 11:52:16

Hi,

when I boot my computer I get when the mpd is loading the message that is failed:

it looked a little bit like this:

/etc/rc.d/mpd, Line 6 abort /usr/bin/mpd /etc/mpd.conf &> /dev/null

This happend only when I use the stock kernel. Only change to the kernel is the AUR package rt2860 for my wifi card.

sand_man · 2008-12-23 22:28:38

what is line 6 of mpd.conf?

tehabe · 2008-12-24 01:46:38

This is line 5 to 7:

error_file            "~/.mpd/error"
pid_file              "~/.mpd/mpd.pid"
state_file            "~/.mpd/mpdstate"

tehabe · 2008-12-24 21:26:06

Now I get this message even when I start mpd when the computer is running, I get this message:

% sudo /etc/rc.d/mpd start
:: Starting Music Player Daemon
/etc/rc.d/mpd: line 6:  6391 Abgebrochen             /usr/bin/mpd /etc/mpd.conf >&/dev/null

The line 6 in question isn't from mpd.conf but from the daemon script in /etc/rc.d/mpd. However if the example you gave is your mpd.conf then it would be interesting to see how it looks. I can't understand how this could be connected to the kernel. To me such an explanation doesn't make sense.

Anyway the full mpd.conf might be of interest to track down why the daemon fails to execute.

tehabe · 2008-12-26 18:50:59

My full mpd.conf. I don't understand the connection myself. I only know the problem started when began to use the stock kernel. I did this because the my kernel before that didn't like my udev and broke the symlinks for the DVD drive.

driver_options "period_size=50000;use_mmap=true"

Is that part necessary?ฆ

Zariel · 2008-12-26 22:34:29

do the files and folder exist which you specified?

It should reduce the load on the processor I didn't see any difference.

All directories exist.

Currently it only fails when I boot the computer, when the computer is up and running I can start mpd via the start script.

I updated the kernel yesterday to 2.6.28 and it started okay but when I installed the AUR package rt2680 it failed again. I now it makes no sense whatsoever.

thunderogg · 2008-12-27 17:26:19

Does the "mpd.pid" exist? Did you create it with "touch ~/.mpd/mpd.pid". If it exist, try comment out the line 6, and see what happens. You are supposed to be able to run without a .pid file, but then you have to remove it from the configuration file.

Hm, yes. And this line is: "/usr/bin/mpd /etc/mpd.conf >&/dev/null"
It is trying to execute "/usr/bin/mpd" loading "/etc/mpd.conf" and it fails.
Why? Can't it read /etc/mpd.conf for some reason? How about rights? Is it really there? Remember than when you boot, mpd is run as root. How do run it manually--as a user?

I fails to start at boot but I can successfully start it when the computer is running, with:

sudo /etc/rc.d/mpd start

thunderogg · 2008-12-27 20:55:23

OK, I see. Everything is as it should except that it isn't working. The rt2680 is a wifi thingie, isn't it? And everything worked before? Sounds like a conflict at startup time. Can't you start mpd a bit later? Either by putting @mpd in the DAEMON, or "/etc/rc.d/mpd start" in "/etc/rc.local". Try to put "sleep [seconds]" before it to delay the launch further. I don't know ... maybe it's worth a try.

thunderogg · 2008-12-27 21:26:53

Or you may start it automatically after login ...

Hi,

just noticed your conf file is missing a quotation mark in
port "6600" <--there
..that is, if that is a copy/paste of your config, of course.

Cheers

I have the same problem as this but when I shutdown (shutdown hangs). Booting is fine. I still haven't found out what is causing it and the only solution I found is to pkill mpd in rc.local.shutdown
This doesn't help you though.

That would have been to easy, so it didn't solve my problem.

Try:

music_directory       "/home/thomas/music"
playlist_directory    "/home/thomas/playlists"
db_file               "/home/thomas/.mpd/db"
log_file              "/home/thomas/.mpd/log"
error_file            "/home/thomas/.mpd/error"
pid_file              "/home/thomas/.mpd/mpd.pid"
state_file            "/home/thomas/.mpd/mpdstate"
user                  "thomas"
bind_to_address       "127.0.0.1"
port                  "6600"
filesystem_charset    "UTF-8"

mixer_type "alsa"
mixer_device "default"
mixer_control "PCM"

audio_output {
    type "alsa"
    name "ALSA audio output"
    driver_options "period_size=50000;use_mmap=true"
    }

A side note: do you realize there is a `mpd` user on your system and that you should probably use -that- as the user as which mpd should run?

sm4tik · 2008-12-29 23:46:28

I'm not absolutely sure about this, but it seem to me there is no "driver_options" available anymore in mpc.conf. Check the mpd.conf man for details. In the meanwhile, you can try

audio_output {
    type "alsa"
    name "ALSA audio output"
    period_time "50000"
    use_mmap "yes"
    }

Cheers

I downgraded from the git to "current" stable 0.13.2 and recreated the hole library. Now it seems to work again.

You might know 0.14 is the current stable, so be prepared to face your problem again once mpd gets updated in extra. Using git here and had a few problems getting it going a while back, but once I got the config figured out, it's all good! Just see the man pages once you upgrade

So, 0.14 is in testing and I got my problem back. But I also got some new information on the problem. This is the output of mpd on boot up.

binding to address for 127.0.0.1
can't lookup host "127.0.0.1" at line 9: Address family for hostname not supported

One possibility for a work around is, to remove this line from the mpd.conf:

bind_to_address "127.0.0.1"

The problem is the config file. In version 0.14, there isn't any option for http_buffer_size or something like this.
I removed this line and mpd starts without any problems.

that's what fixed it for me as well.

...funny thing, now MPD starts, but without PulseAudio Output. Either I have sound, but MPD uses Alsa or something else, or I have no sound.

My Config is everytime the same,

audio_output {
type "pulse"
name "MPD PulseAudio Output"
server "localhost"
sink "alsa_output.pci_8086_27d8_alsa_plackback_0

or only

audio_output {
type "pulse"
name "MPD PulseAudio Output"
#server "localhost"
#sink "alsa_output.pci_8086_27d8_alsa_plackback_0

In the logs, I can find that mpd's connection with pulseaudio is refused.

I have added mpd to the following groups "pulse, audio, pulse-rt, pulse-access" and activated "network access" and "not force authentication" but nothing helps.

When MPD uses Alsa or something else, there isn't any stream in the streamlist from pulseaudio.
