Using pipewire as a system daemon

I have installed Slackware -current as a VM to experiment. At the moment I have a cron job that will stream audio (the news) at specific times. As my intention was to have the VM run without logging in I used /etc/rc.d/rc.pulseaudio for system audio setup unfortunately the sound was muted after every reboot which meant that I had to login and unmute it and reset volume level. To combat this I put:Code: amixer sset Master 90% unmute in rc.local, this fixed the problem.

1) Is there a better way to have done this?
2) ... and this is my main concern, am I able to utilise pipewire as a system daemon to achieve the same ends. Signposting would be appreciated
