Volume control via Mac keyboard under macOS 10.15.7 does not work.
As soon as I call up the keys for loud/quiet, the volume jumps to the minimum level.
Please fix this bug as soon as possible.
Hi Damien,
I’d like to ask you to comment on my report.
Burkhard
Can you share the Debug info?
There is a very old thread that talks about problems with media buttons. I can not understand how software that deals with media fails to solve media button problems
Hi Jacob,
here is an actual debug info.

Regardless of the problem, remove your personal information from the Debug info.
Max. memory for audio buffers: 31744MB
I would set this back to 4GB or less. So much space for audio buffers is of no benefit. It does cause problems that there is no more space left for OSX and other applications.
Volume control is strange. Because you are using the standard functionality of OSX. How does the volume control respond with exclusive access turned off?
Exclusive access: Enabled
Hi Jacob,
I have changed the settings you mentioned – 4GB max. memory for audio buffers and exclusive access turned off. Unfortunately, the volume level still jumps back to the minimum value when I want to adjust it with the keyboard.
Burkhard
And if you listen to music with another Music Player, does the volume respond normally?
Yes, no problems.
Burkhard
What a shame, the update version 1.7 did not fix the keyboard control problem. Why not?
Burkhard
What if you deactivate this keyboard volume controle?
I think it is in your case that not Audirvana but OSX should control the volume. If this option is enabled, Audirvana will probably catch the commands, but won’t do anything with them. Or you have to activate the volume control of Audirvana.
Hello Jacob
honestly, this is curious, because then I do not understand the logic of the switch for “Use Keyboard volume…”. If it is on, the volume adjustment does not work, but if it is off, it does. What’s the point, the function is the exact opposite of what it claims to control - even though I have the “Use Keyboard media keys” switch set to active.
Burkhard
Here’s what I think of understanding how it works.
When the switch is on, Audirvana receives the keyboard commands for the volume. But if you don’t have the volume control active in Audirvana then nothing will happen with it.
When you turn the switch off, OSX will receive the commands and then adjust the volume in the internal mixer.
If you activate Audirvana’s volume control and activate the keyboard, you can use Damien’s more audiophile volume control.
The keyboard media keys is about the play pause previous next buttons.
Hi Jacob, It does seem somewhat counterintuitive needs a info button pop up to clearly explain functionality. Great detective work man!
Pour yourself a cold MQA and put your feet up 
No MQA in my house. 
Hi Jacob,
thank you for your attempt to interpret the actual state. Unfortunately, it remains unanswered why, with the keyboard volume on, I can’t adjust the volume with the volume up and volume down keys. When I try plus or minus, the slider always jumps back to the minimum position. This makes no sense.
