How to get system volume control on Dell monitor

[cutcopypaste]

I have a DELL U2715H Display and while the HDMI carries the audio, it makes it so I cannot use the system volume to control the audio output to the speakers I have plugged into the monitor.

I got a recommendation for Soundflower, and installed that along with soundflowerbed, but unfortunately the sound quality is VERY bad. Tons of tics and artifacts and stutters..

I wonder if there's another way to get system wide volume control?
I can fiddle with the volume on specific apps, but then when i'm on headphones or whatnot it gets tricky to keep things at all consistent. (and right now for my music to be pretty loud in itunes, the volume control is at less than 5%...)

Why go through the monitor at all and not use the direct output of your Mac?

I'm trying to keep the hookups to a minimum when I dock.. this way the audio cable can live in my monitor

 

[Gwendolini]

And HDMI is listed in the Sound Output?

This happens to me too

I had to add speakers with a volume knob.

on most of the dell monitors like that you can use the buttons on the bottom right of the monitor itself to adjust the volume when on HDMI. It's not the same as using the keyboard settings from your mac, but it's easy enough to do. That's the simplest, low cable bloat solution I can think of.

Some monitors allow using DDC for controlling their internal speaker volume along with brightness & contrast.
Mac displays don't use DDC at all.

I write a command line DDC setter for Mac here:
http://github.com/kfix/ddcctl

to bump the volume on your 1st display 5 "ticks" (the actual dB change varies between monitor brands), you'd do:
ddcctl -d 1 -v 5+

However, that's not nearly as well implemented across manufacturers as the brightness (-b)/contrast (-c) controls.

No one has yet made a nice status bar slider or Prefpane that controls all options on multiple external monitors.
So I use my cli tool with Today-Scripts/ & Karabiner for quickly toggling my monitors bright and dim.

Just hooked up my shiny new Dell SE2716H and same issue here with audio over HDMI. So I ran a male to male headphone cable from my mac mini to the audio in jack on the monitor which allows me to use the mac's system and keyboard volume controls.

...

Dell monitor without any audio jack line-in port (audio in via HDMI or DP only).
Soundflower + SoundflowerBed provides buggy results (intermittent loss of audio, buzz, ...
The monitor is compliant with DDC/CI. Could DDCCTL be useful to me? Is it "mature" and user friendly now?
I run OSX 10.12 +

Best,

I have a related issue, and my scenario is that I have a Mac Mini, and I have headphones already using the headphones jack, so I'd really love a solution that can go through the monitor display port. I will probably have to find speakers with their own volume knobs. It's just odd that Dell doesn't provide this control when they have an audio out.

I checked - at least the Dell Precision monitors don't have audio adjustment in their menus.

If you have a free USB port you could get something like the SoundBlaster Play! 3, which has an analog TRS connector for speakers and headphones. Once connected, no driver installation needed, it shows up under SOUND OUTPUT in System Preferences and the Volume icon in the Menu Bar.

Topping this thread. Curious if anyone has gotten macos system audio controls to work with the Dell P2715Q audio output.

Thanks I’ve since upgraded but kept the monitor and will have a look.

Thanks for this answer. eqMac seems to work even on Big Sur (Intel) with U3419W over USB-C.

Reviving an old thread here. Curious if eqMac works with the new M1 Macs with its full security mode that hinders kernel extensions. Does eqMac install kernel extensions?
