[Solved] MPD - Failed to open audio output

botika · 2014-01-15 00:45:35

This is a typical problem, but can not find a solution I searched for more. sound works, everything works, but when I give the play throws me this.
/etc/mpd.conf audio_output

audio_output {
	type			"alsa"
	name			"My ALSA Device"
	device			"hw:0,0"		# optional
	format			"44100:16:2"	# optional
	mixer_type		"hardware"
	mixer_device	        "default"
	mixer_control	        "PCM"
}

~/.asoundrc

defaults.pcm.card 0
defaults.pcm.device 0 
defaults.ctl.card 0
defaults.pcm.rate_converter "samplerate_best"

/etc/passwd

mpd:x:45:45::/var/lib/mpd:/bin/true

/etc/group

audio:x:92:pcare,mpd
mpd:x:45:

aplay -l

He followed these guides: archwiki, wikia, musicpd , and many more forums and can not find the solution.
What should be my output and my asoundrc?

Regards

Solution: the solution is to reinstall mpd with alsa settings in / etc / asound.conf

Hi

Remove (or comment out) audio_output

And start mpd again.

mpd can auto-detect any available audio devices.

Good luck...

Try following mpd configuration:

device			"plug:default"
or
device			"plughw:0,0"
or
device			"plughw:PCH"

Maybe the soundcard is forced into specific format by something else. Is specifically dmix plugin working okay? With different formats?

botika · 2014-01-18 04:17:15

I don't have dmix running, because here puts that is needless. Thanks but not work any config.

emeres · 2014-01-18 17:31:00

I am aware of that, which is the reason I have asked you, if dmix is working okay (it is enabled by default as stated in your source link), meaning are you capable of playing multiple sounds, different sound-formats (especially with combination of stated plug[hw] combinations) at the same time through aplay? If yes, then alsa is not the problem.
Is mpd from repository or AUR or manually build? Try building the newest version with mpd-git package in AUR.

I had a similar issue recently which I resolved by removing my ~/.asoundrc and setting my card defaults in /etc/asound.conf instead:

defaults.ctl.card 1
defaults.pcm.card 1
defaults.timer.card 1

botika · 2014-01-19 23:09:59

Solved !!! When reinstalling mpd with this configuration /etc/asound.conf

defaults.pcm.device 0 
defaults.ctl.card 0 
defaults.pcm.card 0
defaults.timer.card 0
defaults.pcm.rate_converter "samplerate_best"

Successfully detected a alsa automatic with this /etc/mpd.conf

user "mpd"
pid_file "/run/mpd/mpd.pid"
db_file "/var/lib/mpd/mpd.db"
state_file "/var/lib/mpd/mpdstate"
playlist_directory "/var/lib/mpd/playlists"
music_directory "/var/lib/mpd/music"
log_file "/var/lib/mpd/log"
sticker_file "/var/lib/mpd/sticker.sql"

Ie the solution is to reinstall mpd with alsa settings in / etc / asound.conf. Thank you very much to all. Regards

Proinsias · 2014-01-20 02:42:15

Glad to hear you got it working. In my case a reboot as opossed to reinstall, after modifying the asound, was all that was required.
