I have encountered the opposite problem.
Some speakers turn themselves off automatically when they don't detect any sound on the line for a certain amount of time.
So when you want to have your monitoring application ring the alarm on the speaker, you need to be aware of it so you don't miss it.
Depending on the speaker you may need to be continuously playing some very low volume audio to prevent them from auto-turning off.
- aarongolliver 6y agoI have this issue with a subwoofer - coupled with a bad amplifier/grounding/(something?) it creates an immense WOOOOF every time it turns on and off. This causes my house to shake 15 minutes after I go to bed, just as I'm about to fall asleep. Have definitely considered auto-starting something that played a continuous low tone to prevent it from happening.
- brokenmachine 6y agoWhat model is it? I have a sub that does a small thump when it turns on/off but nothing like you describe.

- formerly_proven 6y agoAlso prevents audio drivers putting your hardware into a low-power standby state (especially ridiculous on a desktop), which causes ~1 s of lag when starting to play audio again.
- Negitivefrags 6y agoThis is often caused by digital audio. It takes most digital decoders a little while to start streaming again when a new digital signal comes in. I’ve noticed it in every setup using digital audio output from a PC I’ve ever used. To fix it I believe it’s possible to send encoded complete silence, and that still works to stop the decoder from stopping. I don’t know why there would be a delay, but my guess is that it’s something like waiting for the next “block” of audio to start to start. I’ve noticed when bitstreaming compressed audio formats that the delay is longer, but also a bit arbitrary which I suspect is because the next block start position depends on where exactly you paused the video.
- secondcoming 6y agoI seem to recall that during events where there is the 'one minute silence' beforehand, the TV commentator would have to interrupt the silence so that something doesn't get turned off automatically. I can't remember the exact details.
