Sep 30, 2015 5:08 PM in response to foundryfireby Paul Conaway,If you select "About this mac" from the apple menu and then select system information from the dialog box that appears you get the system information application. Under the hardware section there should be an audio section. Do you see your speakers listed? Are your speakers connected via the headphone jack or via USB?

Oct 1, 2015 7:03 AM in response to foundryfireby joelhowa,Same issue with my HiFiMan HM-101 USB soundcard/daq that I use at work. I installed the GM and it's been broke since then. I've tried everything to get the sound control back... hopefully Apple releases a patch to fix it at some point. Worked fine with Yosemite and Mavericks.
Ohh... and when I goto the Audio section in the system information I get: "There was an error while gathering this information."

Oct 1, 2015 9:16 AM in response to foundryfireby foundryfire,I am not very happy issue with this OS upgrade issue at all. These speakers have worked with every other OS upgrade for years - including for my previous MAC. This is a very frustrating issue.
If anybody has a suggestion as to how I can correct this, I would be more than appreciative.

Oct 1, 2015 10:31 PM in response to foundryfireby Schniggl,Found the solution. My volume control was grayed out as well. Goto System Preferences/Sound and select the correct output. After the update my default was set to the external HDMI monitor and it worked when I switched it back to system speakers.

Oct 2, 2015 6:30 AM in response to foundryfireby ThoughtfullLion,I have the same problem. Speakers connected by usb would appear to now have a fixed output. My speakers (Microsoft Digital Sound System 80) are correctly recognised, but in System Preferences when selected, I am told "The selected device has no output controls" There is an output there but it is very low. Switching back to Internal Speakers enables both Balance and Output Volume.
I have gone back to using the internal speakers for now but the sound quality is terrible when compared to the digital MDSS80 system.
These speakers have worked perfectly under the previous operating systems.

Oct 2, 2015 2:11 PM in response to joelhowaby yxz10,Same here, I also have the same USB device. At least the volume is still adjustable in an application like iTunes, however it's really inconvenient.

Oct 5, 2015 3:24 AM in response to foundryfireby Ollesv,Same problem here. Using a USB DAC & amplifier with Burr-Brown Japan PCM2702 on a Macbook Pro 2015. I use this for my headphones at the office and need it to amplify the signal enough. Please Apple, fix this...

Oct 5, 2015 11:01 AM in response to foundryfireby nekitor,I'm having a similar issue with my Creative Xmod USB audio device and El Capitan. When the Xmod is selected as the output device, I'm able to get sound out of it, but the volume controls are disabled. However, when I switch the output back to headphones plugged directly into my Mac, the Xmod's build-in volume controls are then able to control the system volume.

Oct 5, 2015 1:07 PM in response to joelhowaby Shadester,This is exactly the same issue I have with my Hifiman HM-101. "The selected device has no output controls"
