How to fix choppy sound in wired Logitech headset, that started after updating macOS

I installed a few updates yesterday and after that, the sound in my Logitech wired headset started coming out choppy. The sound is distorted every 0.25 seconds - as if someone muted the sound regularly every quarter of a second, but instead substituted the gaps with static.


The following are the updates I installed:


Based on troubleshooting, the following are some observations:

  • The same headset is working fine in another MacBook Pro that doesn't have the updates.
  • The built-in speakers in my own MacBook Pro are working fine.
  • The problem is not isolated to one of the USB ports. I observe it in both the ports.
  • The same headset was working fine on my machine a day before I installed the updates. I don't remember doing any system level changes between then and now, except installing those updates.
  • I haven't tested any other headset in my machine. So I am not sure if the headset brand or model has anything to do with it.
  • I haven't tested any 3.5mm headsets so I am not sure if the problem is with USB headsets only.


This made me conclude that the updates somehow are causing problems with either the USB ports themselves or the audio output through them.


Some solutions that I considered but didn't choose to pursue:

  • Removing Sierra and going back to El Capitan. It would cause huge inconvenience - creating the backup, creating the installation USB, restoring data. Also this is a corporate machine and I am not sure if I am allowed to do it or what is the process.
  • Approaching my corporate help-desk is something I've considered, but they'd probably just ask me to get another headset. I don't want to go through the approval process again.
  • I didn't configure Time Machine so I can't go back to any point in the past.


Is anyone else facing this issue? How can I resolve this?
