El Capitan and missing volume control for speakers

Hi,

I solved the problem by investing in a small volume control device (Fostex PC-1e, about $25 on Amazon). Installed between the DAC and the speakers, it works very well.

Good tip. That should help anyone stuck in a situation with no hardware volume knob. In my case, I have an amp with a volume knob, but I expect the software volume controls to work like they did in 10.8 - 10.10.

same problem,... have a volume control, but no balance...

have the same DAC and same problem... let me know if u found any joy... txs

Hi

Select -Sysyem Preferences

- Sound

- Click on Internal Microphone( which appears in window: Select a device for sound input

Then tick box: Show Volumn in Menu bar

And all should be well!!

No, that has nothing to do with the issue. Showing the volume in the menu bar is not a problem.

The problem is that the volume can't be adjusted (greyed out, disabled) for certain USB DAC devices, something that worked before El Capitan.

Having this issue myself currently! 2012 i7 Mac Mini running El Capitan

Have a Nuforce USB DAC connected; can't control volume on my keyboard, it's greyed out and the settings state 'The selected device has no output'!

However, this has worked recently with a NAD D1050 DAC via USB and KEF X300A speakers, also connected via USB!

What's the issue and why has it cropped up all of a sudden?!

Thanks

Thanks; but of no use as this is being fed via USB and does exactly the same even trying your solutions!

same problem.

10.11.5; 2015 mbp 13 inch; 3.1g; 16g.

i just bought a Sound Devices USBpre 2. first time everything looks fine but when i change volume with keyboard shortcut or volume control of softwares nothing happen. only the volume logo shows on screen was changing.

second time without restart computer it turns gray as you guys experienced. but i can control volume through one of the softwares (KORG AudioGate 4)' own volume bar. not the others such as WaveLab Element 7. nor iTunes. in this case i can't choose this device from audio midi setting. its grey too.

i tried add multiple devices setting on midi set up then i can choose the device. grey short cut key and no control from WaveLab.

a lot of works are depend on it. terrible isn't it?

Hi people , I had the same issue , found this app http://www.volumemixer-app.com/ . works with Sierra too.

Hope it helps you. don't forget to mess with the settings of the app to auto select on start which will be your default output device.

Anyone had any luck with Sierra??

A later update in El Capitan did fix usage for me (Creative X-Mod), and that functionality has carried over into Sierra. So, in my own case, yes -- the function is working again.

I'd do a Time Machine backup, upgrade & see if it works for you. Then if not, you can revert back to your previous version. That's what I had done when Mavericks first released & functionality wasn't sticking & just had to wait for a while.

Hope that helps!

This solved it but in a slightly different way. I had removed an output device and the system went automatically to the internal speakers in the control panel. What I did was simply select internal speakers again and it was fixed. Basically resetting it...
