Ever since Android 7.1.1 I am unable to find the page (activity screen) to set, on one screen, the volume for the various audio outputs, such as notificatios, media, etc. Is there such a screen inherent in Android 7, or do I need to find an app for that. Thanks for your help.
Yes this is found under Settings → Sound i.e
If for some reason you can't find it or is hidden, then just grab a third-party activity launcher application from playstore e.g Quick shortcut to access
Install Quickshortcutmaker from Playstore
Select normal search - under input box type sound and click search
- In search results it will show Settings click it, and expand the list you will find "Sound & Notification" then click try (or create shortcut by pressing create).
I had "Volume" under "Settings/Sounds", but it looked like a heading, so I never clicked it. Not smart I suppose, but now I can set the volumes for "Notifications", "Media", and "System". Great answer from @xavier_fakerat. Thanks.
