Wasn't SONOS already exposed for being a CIA front?
Like streaming the audio encrypted to a receiver station.
I would have expected the hacker looking into this instead.

> It can also play from Spotify etc. and the binaries for that are probably bloated like most cloud services. One of my favourite things about my Sonos setup is that it avoids me having to run bloated cloud service binaries on my personal computing devices. (Most notably, of the services I use, SiriusXM digital services have always been most unpleasant to use.)
That's what made me ditch sonos 4 years ago. Being forced to run everything through the awful Sonos app instead of casting from the dedicated app or playing through Bluetooth without any delays.
Last I checked, the Sonos app is better than the SiriusXM app. Not that I use it much anyway, I mostly use Sonos/Sirius via Alexa control.

But the cost of that convenience is in giving random devices full access to both your LAN and the Internet. You could VLAN them into a separate audio-devices network and whitelist their Internet access but the effort in doing that would seem to outweigh any advantages of network audio devices. Sometimes a dumb, network-unaware Bluetooth audio sink just works...
I've never found either Bluetooth, or the Sirius app to "just work". And Sonos is an established company, their speakers aren't "random devices" in the same sense as random IoT devices from Amazon.

You don't know. Traffic is encrypted and articially enlarged with some spooky Mesh Networking talk.
And one of the founders got caught.

The speaker itself could be turned into an one giant microphone.

#47Clever. Don't go frying the amp hooked up to those big towers. :)
IIRC the only way to fry an amp is to hook it up with no load. Putting not enough load will fry the load when the amp overdrives it, putting too much load will simply make for a quiet speaker.
That's not correct. These are class D amps. No load = no current flowing.
Too much load (low ohmage speakers - things that dip below 1.5ohms for extended intervals) means too much heat dissipated as switching current in the amplifier IC, which burns out a driver FET or some other part of the silicon die.

It looks like the processor is doing some form of DSP, so some smarts are required. It can also play from Spotify etc. and the binaries for that are probably bloated like most cloud services. With this said, had this been a lower end product, the SoC would probably have been an Allwinner or MTK with a soldered Realtek SDIO WiFi solution.
What I see on photos is a genuine PCI Express WiFi, just like one you see in notebooks. And the fact that the module is 3rd labeled, suggests that either Broadcom or Realtek is involved
Why do you need PCIe WiFI for audio?!

Ugh, Strobist. This is what I get for typing this on my iPhone :-\
