I installed this via the .deb file on my RPi4 and it seems to be having an issue with a device that doesn't exist. Here is the error that is listed in the syslog. Below that is what is returned when I do an aplay -l. Audio plays fine via the device otherwise, I just wanted to get the webui working so I could control it easily since it is a headless setup. Any suggestions would be appreciated.
