[SOLVED] MPD only outputs screeching sound

splatterdash · 2012-07-02 19:14:02

I just did a massive upgrade (about 1 Gigs of download, total) after a few weeks of not running pacman. After this upgrade, my MPD is behaving weirdly. Whenever I try to play any audio files, it only outputs a very loud screeching sound.

I didn't update the config. All other audio channels seem to work fine (YouTube plays ok, playing audio files using mplayer also works). It's just MPD that's doing this.

Any clue on how to fix this? Oh, and by the way, I'm using ncmpcpp to play from MPD.

Here's my mpd.conf if it's of any use.

EDIT: sorry, I pasted the wrong file. This is the correct one.
EDIT2: removed config, has nothing to do with error

Hmm, i see nothing wrong there. Config is fine. You seem to be using pulseaudio, which *should* be failproof also. Since you mentioned all other apps work i really cant see the source of the issue.

There was a major pulseaudio update tho, but i dont think much changed there. Cant hurt to check tho. the configs are in /etc/pulse or in ~/.pulse

That's why I'm confused .

I'm running it as a user process instead of a daemon. Could this somehow be the cause? (FYI, it's always been run as a user process).

I did a diff of .pulse/default.pa and /etc/pulse/default.pa. The only different lines are these:

< ### BEGIN: Equalized audio configuration
< ### Generated from: pulseaudio-equalizer
< load-module module-ladspa-sink sink_name=ladspa_output.mbeq_1197.mbeq master=alsa_output.pci-0000_00_1b.0.analog-stereo plugin=mbeq_1197 label=mbeq control=3.0,3.0,7.3,7.0,3.0,-1.0,-6.6,-6.3,-4.5,-4.0,1.1,1.2,5.8,7.9,8.8
< set-default-sink ladspa_output.mbeq_1197.mbeq
< set-sink-volume alsa_output.pci-0000_00_1b.0.analog-stereo 65536
< set-sink-mute alsa_output.pci-0000_00_1b.0.analog-stereo 0
< ### END: Equalized audio configuration

and this:

load-module module-stream-restore restore_device=false

In /etc/default.pa, the first block of lines does not exist and the second one exists without the restore_device flag.

I'm experiencing the exact same problem since updating MPD yesterday. Disabling software mixing seems to resolve the problem, perhaps a bug in the latest version of MPD (my machine gets updated everyday so it seems to only be in the latest version).

Cheers,
Paul.

The same here with oss. Downgrading mpd solved my probleme until they fix it.

Rasi · 2012-07-04 18:39:51

please report upstream, sounds like software volume bug.

This also solved mine! Thanks for the tip !

Shall I mark this as solved? The bug is still not fixed, but this works for now..

Ha, add my voice to the chorus. Downgrade fixed it. Whomever opens the bug report, please post a link in the thread.

Their bug tracker points here: http://musicpd.org/mantis, which is the main page of their wiki. I can't seem to find any proper bug tracker there..

graysky · 2012-07-08 16:15:39

...so did anyone open this bug report with upstream? Still present in the git version.

EDIT: Did it myself. http://bugs.musicpd.org/view.php?id=3515

audio_output {
	type		"pulse"
	name		"My Pulse Output"
#	server 	"localhost"
#	mixer_type   "software"	# optional
#	sink		"alsa_output.pci-0000_00_1b.0.analog-stereo"
}

my pulse setup on MPD, and working fine... *FYI

@martadinata - looks like mine. Playing flac files just fine but mp3 encoded files give static.

userlander · 2012-07-08 23:19:49

Had the same problem, disabling software mixing fixed it for now. Thx 4 thread.

graysky · 2012-07-09 23:46:12

OK! The devs fixed this issue in git. Just wondering when they'll bump the official version. Till then, download the mpd-git package from the AUR and enjoy.

@op - plz mark this thread as solved.
