"MPD error: Access denied" and "MPD error: No such playlist" when trying to load playlist file outside working directory

[tillheilmann]

I cannot get mpc to load .m3u playlist files when said files are not in the working directory. As the output below shows, I get either an "Access denied" error (when the playlist file is on another APFS volume) or a "No such playlist" error from mpd. This is not a problem when the file is in the working directory. It does not seem the be file permissions related. Any ideas? Thanks!

~$ ls *.m3u ~/Music/*.m3u /Volumes/Hackintosh-HDD-1/Music/*.m3u

Using absolute paths is only allowed if the client is connected via local socket. Your configuration contains no local socket.

[tillheilmann]

Okay, so I changed my mpd.conf to:

$ cat ~/.mpd/mpd.conf 
music_directory	"/Volumes/Hackintosh-HDD-1/Music"
playlist_directory	"~/Music"
bind_to_address	"127.0.0.1"
pid_file		"~/.mpd/mpd.pid"
log_file		"~/.mpd/log"
db_file		"~/.mpd/database"
log_level		"verbose"
audio_output {
	type "osx"
	name "CoreAudio"
}

But then:

~$ brew services restart mpd
Stopping `mpd`... (might take a while)
==> Successfully stopped `mpd` (label: homebrew.mxcl.mpd)
==> Successfully started `mpd` (label: homebrew.mxcl.mpd)

~$ cd; mpc load ~/Music/sample.m3u 
loading: /Users/till/Music/sample.m3u
MPD error: Access denied

[MaxKellermann]

I think you mixed up "loopback device" and "local socket". See https://mpd.readthedocs.io/en/stable/user.html#listeners

[tillheilmann]

Ah, sorry, okay. I have yet to figure out what the "local socket" is for homebrew installed mpd on macOS. I'll get back to you when I know/understand more...

[tillheilmann]

Okay, I give up. I have no idea how to set bind_to_address properly for this to work. Any hints? Alas, neither the documentation you linked to nor Google helped.

[tillheilmann]

I don't know if my homebrew installed mpd on macOS even has a local socket like the /var/run/mpd/socket mentioned in the documentation. At least, there is nothing in my /var/run/ that looks anything like it.

[tillheilmann]

Okay, so ...

 cat ~/.mpd/mpd.conf 
music_directory		"/Volumes/Hackintosh-HDD-1/Music"
playlist_directory	"~/Music"
bind_to_address		"127.0.0.1"
bind_to_address		"/Users/till/.mpd/socket"
pid_file		"~/.mpd/mpd.pid"
log_file		"~/.mpd/log"
db_file			"~/.mpd/database"
log_level		"verbose"
audio_output {
	type "osx"
	name "CoreAudio"

But then:

~$ mpc load sample.m3u 
loading: sample.m3u

$ mpc load ~/Music/sample.m3u 
loading: /Users/till/Music/sample.m3u
MPD error: Access denied

[MaxKellermann]

Remember this?

Using absolute paths is only allowed if the client is connected via local socket. Your configuration contains no local socket.

You solved my second sentence, but you forgot the first one.

[tillheilmann]

So, this should work?

~$ mpc load /Users/till/Music/sample.m3u 
loading: /Users/till/Music/sample.m3u
MPD error: Access denied

Sorry if I'm being dense.

[MaxKellermann]

No. This command is exactly the same as the one you tried previously.
Which address did you tell mpc to connect to?

[tillheilmann]

So, this finally did it:

~$ mpc --host=/Users/till/.mpd/socket load ~/Music/sample.m3u

Thanks!

[karankumbhar47]

may I know what is in /Users/till/.mpd/socket file or it will autogenerate
