Hi everyone. First of all I beg excuses for my english.

My room has the following configuration: two stereo Five’s and a Sub (gen 2). Five’s are new. The sub is a refurbished one bought on Sonos site in december ‘21.

The sub performs correctly. But two minutes after stopping music reproduction, you can hear one single soft “pop”. This happens also when the Sub is off (flashing green light).

Is it normal?

Diagnostic report 1879570162

Thanx!

Hi @Otellofelix 

Thanks for your post!

I believe you’re just able to hear the Sub powering it’s amplifier down to save energy - nothing to worry about. This is considered normal behaviour, as long as it is quiet. If it gets louder, please give our technical support team a call.

I hope this helps.

I figured this was the reason but I needed confirmation from a technician!

Is 2 minutes standard across all mains-powered amp/speakers, @Corry P ?

Hi @nik9669a 

Is 2 minutes standard across all mains-powered amp/speakers, @Corry P ?

The documentation says 3 minutes, and this is normal for most mains-powered speakers. Home Theatre setups will take up to 13 minutes to power their amplifiers down after the TV signal has stopped.

There’s more info on our Sonos Power Consumption While Idle help page.

So, excuse me Corry P, my sub makes this noise after two minutes… there something wrong?

Thanks again.

Hi @Otellofelix 

I had presumed you were estimating 2 minutes, but I see no signs for concern in your diagnostics - as long as your Sub isn’t powering-down during playback or something, I wouldn’t worry about it too much.

I hope this helps.

Hi Corry P, thanks a lot again!

Anyhow, when a software update is available I will do it right away!
