El Capitan and missing volume control for speakers

I have just updated to OS 10.11 El Capitan. Upon successful completion of installation, my desktop speakers no longer have ANY volume control. I can not control the volume by the keyboard shortcuts on the keyboard nor by the volume control (which is now greyed out) in the menu bar. Note that I can select and use the USB speakers under the Sound portion of System Preferences, but I can not change the volume at all. Everything worked just fine BEFORE this update (which was a couple of hours ago). With the exception of the new OS, nothing else has changed on this computer.


Any thoughts on how I can correct this issue?


Mac Pro; 2 x 2.4 Quad Core; 14 GB RAM; OS 10.11 El Capitan

Speakers: Microsoft (yea, I know...) Digital Sound System 80

I have a Pro-Ject USB Box that shows up as "Burr-Brown Japan PCM2702" in System Preferences. I also have speakers in my display connected to through DisplayPort and it's the same thing with both of them, no volume control since upgrade to El Capitan (worked just fine in Yosemite and earlier versions of OS X).

Just upgraded to 10.11.2 and still no volume control. 😟

Would just like to add that I can echo the problems others are having. My USB audio set-up (Burr-Brown Japan PCM2702) - has stopped working since upgrading to El Capitan. It's still selectable in Sound settings, but when selected the volume is muted and volume control is disabled. Had previously worked without problem in every iteration of OS X until upgrading to 10.11. Googling around it appears quite a number of users are affected by this with no solution forthcoming. Sort it out please Apple!

Same issue here. Dell U3415W connected to retina MacBook (2015) over HDMI via the Apple multiport adapter.


Annoying, but the speakers on the rMB are actually superior to the speakers on the Dell monitor, even when the rMB is in clamshell mode. So I guess it doesn't bother me that much beyond the fact that it appears to be a bug, and all bugs bother me 🙂
