Aux In for Sonos Roam

Currently, this is not supported.

If the USB-C is wired only for charging, this is not “some software business”. Besides that, “software business” could not be as easy as you think it is….

I would be surprised USB is only wired to charging functions. I would see the port being used by Sonos for troubleshooting.

Rearly? Dream on.

Now with the Era 100 & 300 which do have this as a feature, will the Roam also get this feature? 

If it were capable, you'd think Sonos would do it by now; if only to sell more $20 adapters.  The fact they aren't enabling this feature in order to pick up adapter sales from nowhere should tell you it isn't capable.

Yes, and the USB C port on the Era speakers can’t be used for powering the device, only data input (ethernet or audio).  The chances that Roam and Era speakers are using the same hardware for USB is very unlikely.

Certainly the fact that it doesn’t is a good indication that there is some hardware differences in the electronics inside of the different devices. If it were merely a software change, you’d think it would be already done. 

This is not true at all, the usb c is a geneal usb-c but sonos deactivated stuff ,

i am someone that ry things out and the usb-c clearly do data to because a powered eth 100/1000mbit works , the roam is seen on lan cable instead wifi, even the app reconize it ,so charging only is false

let me show you some proof

simple  a dock 

Not all nic chipset works, but some of them do, and i bet the usb-c is just a normal cominucation port without power delivery
