Hi @Gary Leeds UK :
I managed to get the new announcements code working after some wrestling.  Here were my steps:
1. Upload an mp3 file of the announcements to the Controller.  I first created a new (dummy) item in the C4 announcements agent, and then clicked "add" to add the mp3 file.  The new file then showed up as an option in the announcements agent.
2. In the Sonos Network driver, choose "Play Audio Clip" and then the Sonos Room.  You can then put in whatever dummy name you like in the name field.  Finally, I inserted a URL to the filename on the controller.  This is of the form, http://[Controller IP address]/announcements/[File name].  So, for instance, if your C4 controller is at 192.168.0.20, and the file name is Gary's awesome announcement.mp3, you would enter the following URL, http://192.168.0.20/announcements/Gary's awesome announcement.mp3.  (I am not sure if the file name is case-sensitive, but I was careful to match the case showing up in the file name list within the announcements agent in case it matters.)
Finally, my queue will no longer be junked up every time I call an announcement from the favorites list.  I am so happy! 
Let me know if this helps you.
 

Just wanted to express my solidarity with you on this, OP, ha. I wanted audio on all my cams given we use them as baby/kid monitors. Accomplished that on the TVs and the NVR recordings, but it still annoys me I can't natively hear the audio in C4's app or on the T3s. Doesn't feel like too much to ask in 2022!

Thank you! That's awesome, and a feature I will use for sure.

Thanks. I ended up getting it working. There is a hidden URL extension for the Chime that allows all settings to be adjusted from the camera itself. Hopefully this is helpful for someone else also.

tl;dr: Control4 apparently doesn't sanitize SQL queries through the History Agent lookup tool, so don't use quotes in your logging fields.
So, I was Using the "HIstory Data" tab to scroll through history yesterday. Used this before, no problems. Then I wanted to get to a specific history entry, one that I defined myself through programming. I chose it from the "Name" dropdown, and bam, history fails, and any subsequent attempt to query causes "Error 4: max concurrent queries".
I spend a bit of time trying to figure out what's up, to no avail. Then, I found the logs in System diagnostics, and tailed the director log. Well, I see an error like "invalid query for 's'" repeating at a rate of tens per second. Then, I think back, and realize I have a log name that has a possessive, like "Mark's room". Good ol' Bobby Tables back again.
I pulled the power on the EA-5, and changed my logging to remove the apostrophe, and it's back to normal. For any C4 devs out there, make sure you heed this warning, and for core developers, please sanitize your inputs!

For audio:
single tap of the button cycles the auto preset room control driver to pick 1 of 5 pre sets.  If a stream is already playing, a single press will skip to the next of the 5 presets.  
double tap mutes the stream
triple tap turns it off
I use the up/down arrows for audio volume control
When there are lights on the same keypad my dealer bound the load to that button so I can press/hold to ramp the lights up/down freeing up the arrows just for audio control
 
for a few rooms that are highly used I have some additional logic - if the room is off and music button is single pressed pick its own preset, if room is off and double press is selected, join to Room X.  I only did this for rooms that are close to each other where may move back and forth like kitchen/dining room and bedroom/bathroom/walk in closet in the master suite.  Otherwise if I want to join to an already playing stream I'll use my phone or c4 touchscreen.

You can use the Janus Technology BMS driver in conjunction with Yatun Variable driver to visually display (graph) any number that you can access in programming.  It is a great driver.
