After upgrade from 10.12.3 to 10.12.4,
I had an issue with my "Plantronics .Audio 655 D" USB headphones.
Causing frequent sound interruptions and glitches (jumps).
Also found some errors in dmesg as:
---------------------------------------------------------
!isOnline() setting online
IOAudioEngineUserClient[<ptr>]::unregisterClientBuffer64(0x<ptr>, 0xae
IOAudioStream[<ptr>]::safeLogError
IOAudioEngineUserClient[<ptr>] - AUDIO OFFLINE
---------------------------------------------------------
hence, i removed the updated "AppleUSBAudio.kext" and "IOAudioFamily.kext",
and restored the previous Kexts from my backup, which solved the problem.
