Sonos - TTS

[jitterjames]

I switched all my TTS over to the Sonos and have been testing for the last few days and it's working flawlessly for me.  All that happens is the TTS is a bit delayed if the Sonos is sleeping but presumably this is unavoidable.

Are you using a single player or a group for TTS? I have only been testing with a single player.

I don't know if it will help but can you please try replacing these files and let me know what error you get if any.

sorry for the delay. i have been tied up on other things, only just seen your replies i will have a play and get back to you, cheers FYI i was using a group

Hi, I have been using the Beta and it is so very very close to perfection.

i have a regular issue with what appears to be a race condition with saving the TTS file and Playing it back. it starts happening once per day the error when playing back the file is Object Reference not set to an instance of an object. restarting voxcommando fixes this for about another day or sometimes less only 12 hours.

once it starts happening all of the TTS announcements fail. I can work around it by looking for the error in the log file and automatically restarting vox commando but one of my TTS announcements will never be heard so its not reliable.

the portion of the log that fails is

this was the first failure of playback today. just earlier than that today there seemed to be a topology changed event (even though the topology of the groups etc had not changed so maybe this is the cause of the object not set to an instance of an object?

A topology changed event probably indicates that one of your Sonoses has crashed, lost power, or otherwise disappeared or reappeared for some reason. I can see why this would cause an object not found error if VC is trying to play to a device that no longer exists. It is probably something that can be fixed though it will be difficult to narrow it down.

Please update to VC version 2.2.1.9 which I just uploaded and let me know if the TTS is more reliable.
