The easiest way is to use a NAS, which is essentially a network storage device that’s designed to stay on all of the time.

However, there are alternatives, if you really have to switch the PC off. One (suggested by another user here) is if your router has a USB port (some do, some don’t). If so, you may be able to put your music library on a USB pendrive plugged into the router, which will serve that up on the network as an SMB: share. I can confirm that this works on, for example, a BT hub with USB port.

And it’s surprising how much music you can get on a large capacity USB drive!

Thank you.

When i listen to a CD for example - the PC updates it to my music library.And from there to my Sonos.

But when i turn the PC off is not possible to play it on Sonos.

i thought that it was possble to do it without having to buy one NAS or something like that.

The Sonos app is just a controller. The Sonos music library is a collection of filepaths pointing at the tracks stored on your computer. How could Sonos fetch and play those files if the computer is turned off?

Ok i thought that Sonos could storage the music from my library.Not only the path.

Thank you for your reply.
