I was looking to add sound to my DomotiGa installation so I could generate audio alerts and updates.
Since my server does not have any audio out socket, I’ve purchased some USB Speakers: Sweex 2.0 Speaker Set Purephonic USB Speakers:

Sweex 2.0 Speaker Set Purephonic USB Speakers

There was only 1 glitch which took me a whole afternoon to sort. For some reason my user was not part of the audio group so I could not get any sound out.

I eventually realised this and sorted it with this command:

sudo adduser [user] audio

And to control the volume, I use this command:

amixer sset Master 50%

I have then recorded a few voice announcements using TTS (Text-To-Speech) that I can use with events such as:

• “Alert: Front CCTV connection Lost”
• “Alert: CurrentCost connection lost”
• “Mood Scene: Movies, Activated”
• and the geeky “Good Morning” 😎
