Volume does not work in mx keys

[noamgilad98]

my logi mx keys connect to my 2020 macbook pro
when I try to press the up/down/mute volume it does not work, just shows sound icon (picture added)

Is there anything in the Sound app of System Preferences to indicate a reason why the option to change the sound settings is disabled?

Are you using an application that has its own sound settings and bypasses the Mac's own controls?

System preferences -> Integrity -> Accessability -> Allow both "Logi Options" and "Logi Options Daemon"

that didn’t work for me any more ideas? I was even on the phone with a Logitech customer support y and they gave up

Hello and welcome.

That symbol looks like you are using some form of digital audio output connection from the MBP to an external device - HDMI, optical audio, etc. There aren't any volume controls for those types of audio, as they are line-level, and you will get that symbol.

Is your MBP connected to an HDMI display/TV, do you have any speakers connected, etc.?
