Chapter 8: Sonos Controller for PC
If there are updates available, click Update Now to download.
2.
• Your ZonePlayers, as well as your Sonos Controller for PC, will be updated as Sonos components must carry the same soft-
ware version number. This process may take several minutes per device, depending upon your network connection. The So-
nos Controller for PC will automatically close and then re-open during the update process.
• Software updates to a handheld Sonos Controller must be initiated from that Controller, so if you have recently updated the
Sonos Controller for PC software, you will be prompted to update your other Sonos Controllers the next time you use them.
Simply follow the Controller's on-screen prompts.
• If your software is up to date, the message "Your Sonos Multi-Room Music System is up to date. No updates are required"
will appear instead.
Caution: Do not disconnect power from your ZonePlayer(s), or in any way disable your Sonos
Multi-Room Music System while this process is running. Contact Sonos Customer Support if an
error occurs.
ZonePlayer software updates
One or more ZonePlayers may need to be updated when you purchase a new ZonePlayer with a later software version, or if you
plug in a ZonePlayer that was not in use when you performed your last software update. If a ZonePlayer's software version gets out
of sync from the rest of your Sonos Multi-Room Music System components, an alert message will display in the Zones pane.
Click the outdated zone to begin the software update process.

Additional Preferences

Selecting a different wireless channel
The Sonos Multi-Room Music System selects the optimal radio frequency channel during setup. However, if you have other
wireless devices using this channel, you may want to switch the Sonos Multi-Room Music System to another channel to avoid
conflicts, as conflicts may cause audio drop-outs.
From the File menu, select Preferences.
1.
Click the Advanced tab.
2.
Select another wireless channel from the Wireless Channel drop-down list, and click OK.
3.
It may take several seconds for the switch to take effect. If you have music playing, a short music dropout will occur during the
wireless channel change.
