Set default audio to Analog

Hi Everyone. Hoping someone can help me here. I'm using an RPI 4 with LE 9.2 for a home automation project. I'm not using it for video - only analog audio. When I set the audio output device to analog audio it works great but after a few days it reverts back to HDMI. is there any way to make it stay on PI: Analog?

Finally finding the time to circle around to this. Seems the issue is the audio out reverts to HDMI after a reboot of the PI. My temporary workaround is to have my ISY send this command every couple hours to change it back to analog:

{"jsonrpc":"2.0","id":1,"method":"Settings.SetSettingValue", "params":{"setting":"audiooutput.audiodevice","value":"PI:Analogue"}}

There must be start up file somewhere to force this thing to stay with analog.

I'll try the beta if that's my only option but thought I would ask.
