Usually, once you output sound by way of HDMI, you can’t management its quantity out of your Mac. You set it as a substitute on the output machine, whether or not it's a monitor or a TV.
I work on my Catalina laptop computer whereas my mini is within the store and I take advantage of my model new DELL monitor with out my regular audio system, which plug into the headphone jacks. With this setting, my music is loud, even when the monitor settings are low sufficient.
Since it’s troublesome to regulate the quantity by way of the monitor menu, I made a decision to attempt Soundflower / SoundflowerBed. I used to be positive that Catalina would have killed him now.
I used to be fallacious.
In SoundflowerBed, I selected HDMI for the 2-channel output.
In System Preferences, I chosen Soundflower (2ch) because the audio output machine.
Increase. My quantity management got here again to life and my ears are recovering from the assault.
Seeing an outdated buddy proceed to plug in and do what I want is remarkably satisfying. Thanks to everybody who has labored on Soundflower through the years, from Alexander Hudek and RogueAmoeba to MattIngalls and Maciej Wilczyński.
