High cpu usage logd after sleep while using microphone, audio does not work

Reported by: Pi Guy Owned by:
Component: audio Version: VirtualBox 5.2.18
Keywords: Cc:
Guest type: Windows Host type: Mac OS X


  1. Start up a virtual box Windows 7 VM on a Mac OS high Sierra host
  2. Start-up activity monitor on Mac OS
  3. Start up a sound recorder recording
  4. Put the Mac OS to sleep
  5. Wait five seconds and then wake up the Mac
  6. Speak anything into the microphone for a second

Watch the CPU usage rise as shown in the screenshot below. Also, sound recorder inside the Windows VM will not be picking up any audio.

There also may be a crash that is related to this issue. It happens several times a day since I bought this model of MacBook Pro (2018 15 inch) because I use the microphone inside the virtual machine all day for dragon naturally speaking 15. I cannot find a reliable way to replicate this issue, but yet it happens several times a day. I will add more information to this ticket if i find a reliable way to replicate this but over the past month i have not been able to find a reliable way to replicate this. I am hoping this particular issue will be solved accidentally while solving the above issue

Although #18089 is a bit more recent, it has way more activity - probably worth closing this one as a duplicate.
