You can however add this ability by buying one of these you also need some software, see įor Displayport you might be able to use a different approach, this involves redirecting the sound through another program before it leaves the Mac. CEC requires hardware support on the HDMI interface. Besides preserving more of the original data - all conversions like this degrade the signal, it also prevents adding additional latency which at worst can result in the audio becoming noticeably out of sync with the video.įor HDMI displays there is a better approach which sadly Apple so far do not support which is for the Mac to send CEC commands down the HDMI cable to tell the display to adjust the volume. It’s easy to install and has a user-friendly interface. Sound Lock is a free utility software that can limit the sounds coming from your Windows PC. Whereas if the display is responsible for adjusting the volume the process is as follows.ĭigital source -> send to display -> display converts to analogue -> adjust analogue waveform to change volume -> sound played via speakersĪs you can see the later Apple enforced approach removes the need for an additional set of analogue/digital conversions. A free tool to modify your PC’s volume settings. This is because if you adjust it on the Mac the following has to take place.ĭigital source -> Convert to analogue -> adjust analogue waveform to change volume -> Convert back to digital -> send to display -> display converts to analogue -> sound played via speakers the TV or monitor should be responsible for adjusting the volume. For this type of connection with digital audio Apple take the view that the playback device i.e. ![]() All of these run the audio in digital form over the same cable as the video. UPDATE #2: the issue is seen even with driver version 1.0.5 (verified using kextstat that installed version is 1.0.5).Īny advice on how to further debug this? How to verify whether the driver is basically working ok or not, besides the volume control being greyed out?.Apple do not make it easy to control the volume on Displayport, USB-C or HDMI connected monitors. So, there must be another issue, possibly in the driver? no volume control) still persists, even after disabling SIP (as shown here ), which bypasses the signature check.

How is it for you? do you have volume control on max os mojave with helix? ![]() ![]() Now with my new mac mini 2018 and the same helix driver there is no volume control available anymore now. This was quite good, because i do not want to have every youtube video and so on playing at 100% by default as they can be extremely loud.
