I cannot add SONOS One to HA

Hi all,
I don’t know why but I cannot add all my Sonos ONE speaker to HA.
I followed the standard steps

  • Browse to your Home Assistant instance.
  • Go to **[ Settings > Devices & Services]
  • In the bottom right corner, select the Add Integration
  • From the list, select Sonos.

The error message shown is:

No devices found on the network

Any suggestion?thanks

Right at the bottom of the docs there’s a section about disabling auto-discovery and specifying the IP addresses of the speakers - have you tried that?

You’ll need to give the speaker a reserved IP address on your router if you want to make this a permanent solution.

thank you.
I installed HA on a container
Do you know where the configuration.yaml is located?
I found this path in internet /usr/share/hassio/homeassistant/configuration.yaml but it seems that is not valid
thanks
