Make text to speech working again

[voelkerb]

Stuff todo:

• [x] connect speaker and install speaker in other room
• [x] can we then address them separately (is this required anyway)?
• [x] amazon stuff?
• [x] mp3 playback still supported?
• [x] fix software audio device
• [x] test

To use AWS Polly it requires an AWS account that hasn't registered it for over a year. I'll check if mine is still eligible.
