Notifications app not playing audio sonos advanced controller

[ThunderboltsRock]

I have two notifications that sent push messages to mobile devices and also tts over sonos advanced controller device. The text to speech doesn’t announce anything but does raise the volume and has the below errors

TTS using rule machine works as expected only notifications app has the failed tts and raising of volume with out returning to original volume levels post tts

The error appears to refer to a line of code in the driver, so this question might be best answered by the developer of that driver.

Unfortunately the developer of that driver hasn’t been seen in these parts for many months. But if you post on the driver thread, perhaps others will be able to help you.
