I can't change volume with keyboard

[marlboro528]

Hello. I have a problem with the keyboard volume. I connect my monitor with a dp port to hdmi cable and the audio works I hear all sounds including videos, music etc. (I have Realtek ALC221 codec in the motherboard Q150). When I try to change the volume with the keyboard (Logitech K400r with usb receiver) do nothing. I see the volume icon with busy and don't change. If I try to change in the top bar I can't. The only way for change it's to modify in the setting panel.

Thanks for help me.

With HDMI the volume is controlled by the HDMI device not the OS.

Con HDMI il volume è controllato dal dispositivo HDMI e non dal sistema operativo.

Thanks, but there is a method to change volume without I go to setting panel? Any application? Or what type of connection can I use to modify with a keyboard?

If using an HDMI TV you use the TV remote control to adjust the volume.
If using an HDMI monitor you use the monitor's volume controls.
