I’ve read here  that balena-sound does not require an Internet connection to operate. Obviously, if you’re streaming FROM the Internet, you would need it. But for local devices streaming to balena-sound devices, it’s not supposed to be necessary.
However, yesterday, my ISP dropped for about 5 minutes, and all audio quit immediately. In fact it’s how we found out the Internet dropped, because no one was doing anything at the time that would have shown it to be down. I have network monitoring and verified that it was not my router or some other issue on our network
I’m more interested in understanding possible reasons for the drop, so that I can dig in and see what I can find. If anyone can give some ideas, that would be useful. Or if someone knows the full reason and can explain, even better!
