Pulseaudio thing initialization during startup to early and therefore causing an exception?

Setup, Configuration and Use Beginners

Dear community,

After having configured the PulseAudio binding with an RTP sink, I realize the following exception thrown upon OpenHAB startup:

I assume that, at the end, the sink is properly initialized as it goes online. Nevertheless, I wonder what the cause of this exception is or whether I need to adjust my system? Any guidance is appreciated as how to cope with this exception.

Best regards,
Peter

This is probably to do with some stricter config checking on Things recently added to OH. You need to file an issue.

Hello,

It seems that I made an error in the pulseaudio binding documentation.
It shoud be :

activateSimpleProtocolSink=true

WITHOUT the " character around the boolean true

I suppose that is the reason you get this exception.

Hope it will help. I will make a pull request to change the documentation accordingly.

Thanks a lot. Indeed, that helped!
