I am working on a brand new install of asl3 and skywarnplus on a new Pi4b.
The Ariusb interface board is in route.
Is there a way I can play with my skywarnplus settings outputting them to the Pi speaker port while I await the board arrival?
Thnx,

Speaking as a matter of theory,
you should be able to load the drivers for the built-in sound and output to that device as a shell script run at some point during OS load or asl start in a macro.
But the howto comes down to the specifics as to what exactly you are wanting to do.
But yea, all possible.
Sure.
I don't have a rPi running ASL3 at the moment, so I don't remember if the Pi appliance disables the built-in audio output. Guessing it does?
In /boot/config.txt, the line
dtparam=audio=on
needs to be present.
Once that exists, reboot the rPi, then run
aplay -l
to list audio devices.
You'll probably want to use alsamixer or amixer to turn up the audio on the BCM...
Once you know where to throw it, you can use outstreamcmd in rpt.conf to send audio through aplay or something similar.
My line under the node's stanza in rpt.conf looks like this.
outstreamcmd = /bin/sh,-c,/usr/bin/aplay -r 8000 -c 1 -f S16_LE -D hw:0,0,0
This sends the raw PCM audio of app_rpt to device 0, subdevice 0, which, in my case, is the 3.5mm audio output of my rPi 3 model B.
This is a little more latent than what you'll get from an attached CM108.
You could connect dvswitch mobile app from a andriod phone to the node 655100 if that is the one you are using at least that is the only one I see on line or you could setup iaxrpt software on your computer and keep it connected to your node 655100 and it will report out of either you computer speakers or your phone speaker until you get your sound card.
