In this guide, i will walk you through the steps to address this issue. Even if it has, controlling the volume through the keyboard can still be very desirable by users such as myself. So one can see why it can be a problem if the external device has no function control volume. What happens is that a Mac OS X blocks system’s volume control functionality because it is usually taken over by the external device (speaker/headphone) or third party software. In the Apple File System Space Sharing dialog, click Partition. If Disk Utility isn’t open, click the Launchpad icon in the Dock, type Disk Utility in the Search field, then click the Disk Utility icon.

All sound input devices available to your Mac are listed. In the Disk Utility app on your Mac, select a volume in the sidebar, then click the Partition button. (You may need to scroll down.) Click Input on the right, then select the device you want to use in the list of sound input devices. In rare cases, it can also happen out of the blue when you are just doing your routine stuff on your Mac. On your Mac, choose Apple menu > System Settings, then click Sound in the sidebar. The scenario may differ from user to user. When they press the Volume Up/Down keys, they would get the usual Speaker icon which will have no effect and the same result when they try to adjust volume via the mac’s speaker icon. This is also reported by users who are using Spotify or other song/media/audio related softwares where they are only able to control the volume through the software’s interface.

But some users have reported that when they connect their external headphones or speakers to their Mac, they are unable to control the volume through their keyboards or through the sound control on Mac. Click the Output tab, and select Yeti Stereo Microphone under Select a device for sound output. There are hot keys on a typical Mac Keyboard which can be used to control the volume level.
