How can make the play service run after initializing audio driver 'al

I want to play a music in the start service.

Edit a auto start service `play.service`.

    sudo vim /etc/systemd/system/play.service

    [Unit]
    Wants=basic.target
    After=basic.target 

    [Service]
    User=nobody
    Group=nogroup
    ProtectSystem=full
    ExecStart=/usr/bin/mplayer  /home/welcome.mp3
    ExecReload=/bin/kill -HUP $MAINPID
    StandardOutput=syslog
    StandardError=syslog

    [Install]
    WantedBy=multi-user.target

Enable it:

    sudo systemctl enable play.service

Reboot,i find no music play ,so check play service:

sudo systemctl status  play
● play.service 
     Loaded: loaded (/etc/systemd/system/play.service; enabled; vendor preset: enabled)
     Active: inactive (dead) since Mon 2022-10-17 16:51:59 HKT; 1min 27s ago

Re: How can make the play service run after initializing audio driver 'al

basic.target is way too early. Use multi-user.target and additionally sound.target to order things in a sensible way.

And debian is not Arch? Is this an Arch system with debian as the host name for some reason??
