Earlier topics show a Sonos power option to keep Sonos active and keep the PC from sleeping. I don’t find that option under Settings>System>Power & battery. Can this feature be downloaded from Sonos?
Which Sonos speakers are you expecting to have a power plan? The above process should only work for and on Sonos devices that have a battery, Sonos does not expose power settings for non battery powered devices, that is handled behind the scenes.
The power plan for the PC not sleeping is in the PCs (or perhaps Hard Drive’s) power plan, not part of Sonos.
Have you installed the Sonos app on your PC? That is how you get the Sonos Power Plan, and the Sonos Wireless WiFi System Account set up.
It is possible this is S1-only nowadays, with the removal of the http music server from S2, but I have both S1 and S2 PC apps installed so can’t say for sure.

My Sonos speakers are AC powered.
