However, from each app with a volume control such as video/audio menu control from Youtube or Music app, I can now adjust the volume as needed.Ĭlearly, this looks to be an oversight from Apple engineering for neglecting the audio controls for LED Cinema Display on the M1 MacBooks. I tried adjusting the volume control key on my keyboard for low and high volume but it cannot be adjusted or isn't available. Audio is a few times louder than the MacBook Pro 13 speakers but under System Preference | Sound, when the LED Cinema is chosen for audio, the message, 'The selected device has no output controls' is still the response. 'Cause audio was able to output through my LED Cinema Display (Mini DisplayPort version, not Thunderbolt version) as loud as it can be. So just to confirm, I spent more to further investigate and found this cable.Īnd this cable worked near perfect if not perfect. The Caldigit unit also has a built-in Displayport. For my final attempt, luckily, I have a Caldigit TS3 Plus Dock to consolidate my external drives for my new MacBook Pro 13in.
