My USB headset has always worked fine. However, after update to mac os sierra 10.12.4 the sound is chopped.
I hear the sound perfectly in all other outputs (HDMI, internal speakers and headphones).
I have restarted the system twice. I also killed all core audio processes, but no luck so far.
Thanks

I think (but I am not sure) that macOS has the notion of generic USB audio devices (see https://developer.apple.com/library/content/technotes/tn2274/_index.html).
As part of this release, the audio drivers code was changed in the OS source code.
So it could be that the manufacturers (in my case Plantronics) was not 100% compliant with the spec in the 1st case, or it could be that Apple made a programming error in their new driver code.
Currently, the issue seems to be happening with Plantronics devices. I don't have another make to try this with (like Logitech).
I don't remember installing any driver to use this, and it has worked through many updates.
But I'll take a look on the headset website.
Thanks
I couldn't find any driver for my headset in the web. Don't know how to start troubleshooting.
Have you tried contacting the manufacturer's tech support for assistance?
I have the same issue with a Microsoft LifeChat LX-6000 USB Headphone on an iMac.
same problem here with Logitech H340.
I ran my headset Logitech H340 through an cheap USB hub and it works.
I also tried it through the wired Apple keyboard USB port and it works too.
Not ideal but a workaround for now.
I was having this problem with the Logitech H340 headset but attaching it via a cheap USB 2.0 hub fixed the issue.

+1 this issue, I haven't tried a powered hub yet, but I can't listen to anything with my headset while its choppy.
Thanks for the response... Do you mean a beta for the next Sierra update?
Same issue here with a NuForce uDac2 headphone amp... Fine before 10.12.4, fine on same computer with other hard drive with 10.12.1 install
