ovos ggwave-listener error

[MarkusDaum23]

Hello, I am new to ovos and have it installed on a raspberry pi5 in venv-mode. The system seems to work but I have no sound output most of the time. Checking the status of the services i found error-messages in the ggwave-listener service. You find the output below. My sound module is an XVF3800.
