[SOLVED] mpd + pipewire

[arvamircea]

Well I tired:

chown -R mpd:mpd /var/lib/mpd ==> chown: invalid group: 'mpd:mpd'
and
chown -R mpd:audio /var/lib/mpd ==> Getting the same "Permission denied"

Do you think is should change to chown -R cocolino:cocolino /var/lib/mpd?

Not a bug? Well at least an update to the mpd Wiki for smooth brained people like me.

Do you think is should change to chown -R cocolino:cocolino /var/lib/mpd?

Yes, of course.
Also, chown pretty much requires root access to work. You can't just steal other user's files.

Well, you are right changing the owner of `/var/lib/mpd/*` and the user in `/etc/mpd.conf` to my user let me start mpd. Still no audio tho :<
Not sure if it means anything but disabling the fifo output in mpd.conf

Code: Select all

#audio_output {
#        type  "fifo"
#        name  "my_fifo"
#        path  "/tmp/mpd.fifo"
#        enabled  "yes"
#        format  "44100:16:2"
#}

makes the music not start at all, it just says on "paused".

What wiki guide are you using?
The one I see https://wiki.gentoo.org/wiki/MPD#Pipewi ... ptional.29 includes information about running mpd as user and about configuring pipewire output.
It should even work with alsa output too. On my system nothing uses pipewire protocol, they all talk either alsa or jack.

Anyway, if you still can't get it to work after changing user, perhaps there are some errors in mpd's logs?

Yep, I am using the same Wiki.
I have all audio outputs, just in case, Alsa, PipeWire, Pulse and my_fifo.
Logs with all audio outputs enable:

Code: Select all

That's weird.
Anyway, I went ahead and installed mpd just to see what would happen if I ran it with the default config (except of user, which I changed to myself). It failed to connect to autodetected alsa (with a similar host-down message), but then proceeded to autodetected and connect to jack.
If you feel like giving this a shot, go ahead and enable USE=jack globally. Admittedly, on your system it does look like a workaround to a workaround at this point. Unfortunately, I've ran out of obvious ideas and since I currently have no use for mpd, I'm not going to do a full-blown investigation into that mpd-alsa problem.
Perhaps someone else could come up with a better option for you.

Thank you @paulj ! Link to solution.

Steps to fix:

1)

Code: Select all

sudo cp -r /usr/share/pipewire/ /etc/ 

2)

Code: Select all

vim /etc/pipewire/pipewire-pulse.conf 

3) `/etc/pipewire/pipewire-pulse.conf` should have the following:

Code: Select all

pulse.properties = {
    # the addresses this server listens on
    server.address = [
        "unix:native"
        #"unix:/tmp/something"              # absolute paths may be used
        "tcp:4713"                         # IPv4 and IPv6 on all addresses
        #"tcp:[::]:9999"                    # IPv6 on all addresses
        #"tcp:127.0.0.1:8888"               # IPv4 on a single address
        #
        #{ address = "tcp:4713"             # address
        #  max-clients = 64                 # maximum number of clients
        #  listen-backlog = 32              # backlog in the server listen queue
        #  client.access = "restricted"     # permissions for clients
        #}
    ]
    #server.dbus-name       = "org.pulseaudio.Server"
    #pulse.min.req          = 128/48000     # 2.7ms
    #pulse.default.req      = 960/48000     # 20 milliseconds
    #pulse.min.frag         = 128/48000     # 2.7ms
    #pulse.default.frag     = 96000/48000   # 2 seconds
    #pulse.default.tlength  = 96000/48000   # 2 seconds
    #pulse.min.quantum      = 128/48000     # 2.7ms
    #pulse.idle.timeout     = 0             # don't pause after underruns
    #pulse.default.format   = F32
    #pulse.default.position = [ FL FR ]
    # These overrides are only applied when running in a vm.
    vm.overrides = {
        pulse.min.quantum = 1024/48000      # 22ms
    }
}

Notice that `"tcp:4713" # IPv4 and IPv6 on all addresses` is un-commented

6)In /etc/mpd.conf I have the following, but I don't think it matters at all.

    mixer_control   "Master"
    name            "My pulse output"
}

        type  "fifo"
        name  "my_fifo"
        path  "/tmp/mpd.fifo"
