Mac Keyboard Volume Buttons?

Try the volume slider in your Sonos Controller. The hardware buttons are not supported.
Take a look.

I would imagine that the volume buttons on your Mac keyboard will always control your Mac's volume. Since content - I'm sure it's not limited to just music - is played by software, it's possible for those buttons to control the actions of an application (in Sonos' case, changing the track on the currently selected zone). But volume is a function of the computer's built-in sound hardware, and as such those buttons cannot be remapped unless the OS permits it.

As Rainer_B suggests, the volume slider in the Sonos controller software can always be used to adjust the volume of your zones. Or you could set up the Sonos app on a phone or tablet, and use that to adjust the volume too.

This is not true. The volume of the sonos system could be matched to the mac volume. AirFoil doe this too. Of course, turning the volume up on the Sonos speakers would also mean turning up the volume on all other mac sounds, but it's a really nice feature to have. I imagine machine volume can be read and parsed by the sonos controller system.

With spotify I can control the volume just fine. Why not with sonos? Seems like a such a basic feature...

They could make it work with a modifier key, like alt+vol up/down.

(Note that Mac already has alt+shift+vol up/down to change the volume in smaller increments)

Please make this happen. Would make using your Mac desktop app so much friendlier.

I would love to have the mac keyboard volume control the app volume.

Adding my voice to the choir: Would love to have mac keyboard control!

Honestly, I'm surprised this functionality isn't part of the desktop app.

Would be good to be able to control the volume through the keyboard, BUT to have it decoupled from the Mac Volume. You would not want to change the volume of the Sonos devices on your network while you are for example working and hearing something with some headsets on.

Realise this is quite an old thread but I've only just purchased Sonos speakers and using the Mac App to control it. Agree would be very good to control it with the keyboard keys, like Spotify does.
