In the Sonos app, go to Settings > App Preferences and disable Hardware Volume Control.

I have version 15.7 of the Sonos application installed and under "App Preferences", there is no "Hardware Volume Control" menu item available.

According to this article, that setting should be there:

That menu item is definitely absent on my app. I wonder whether it is a Samsung specific issue.

This question is marked as answered yet it remains unresolved. The offered “solution” relies on the presence of a particular menu item which is absent from the contributor’s settings interface

Hi @Matty72 

Thanks for your post!

Could you please share a screenshot of the Sonos app not having the shown controls under Settings » App Preferences? Thanks

Hi @Corry P

The highlighted menu items “Show Lock Screen Controls” and “Home Screen Volume Control” are present under App Preferences. However, the menu item “Hardware Volume Control” indicated in the following knowledge base article is absent:

Hi @Matty72 

Ah! I think it might have been renamed in the app at some point and we didn’t update our help pages. Apologies, and thanks for bringing it to our attention. I’ll see if we can get that page updated.

The option you want to disable is the “Home Screen Volume Control”.

I hope this helps.

Hi @Corry P 

I disabled “Home Screen Volume Control”.but the volume of the Sonos speakers still changes when the hardware buttons are pressed.

Hi @Matty72 

Just to be clear, that option being off should only disable the volume control on Sonos when the Sonos app is not open and on-screen. I just tested on my own Android phone and as soon as I disabled that option, the volume buttons stopped controlling Sonos while I did not have the Sonos app on-screen. Could you please confirm that you are still able to control the volume with the phone’s hardware buttons even when the Sonos app is closed? Thanks.

If you are able to confirm that, please submit a support diagnostic from that phone and let me know the number you are given. Thanks.

You could also try disabling the Show Lock Screen Controls option. Please let me know if that changes anything.

It may also help to reboot your Android device.

I hope this helps.

@Corry P 

It appears to be behaving correctly after disabling “Home Screen Volume Control” and “Show Lock Screen Controls”.

Hi @Matty72 

I guess exact behaviour may change from phone to phone.

I’m glad to hear you got the result you were looking for - thanks for updating the thread!
