Windows 10 May 2019 Update suffers from an annoying audio bug on some PCs, but the good news is that Microsoft has sorted this issue using its latest cumulative update for that OS – in addition to a load of other issues.
Patch KB4505903 comes with a list of bug fixes, but addressing that audio glitch is really an undocumented benefit, and was highlighted by Pete Brown, a Principal Program Manager within the Windows/PAX team focusing on tech for musicians, on Twitter (as spotted by Windows Latest).
Essentially, spikes of DPC (Deferred Procedure Call) latency bog the PC down sporadically, disturbing the playback of audio with obviously frustrating results.
As ever, the cumulative update in question is going to be delivered via Windows Update. Although as Brown notes, you are able to manually do the installation if you wish.
Other fixes delivered with KB4505903 for Windows 10 May 2019 Update range from the resolution of the problem whereby Windows Hello fails to work after rebooting your computer.
Some folks were hitting trouble when resuming from sleep or hibernation, being unable to change their display brightness, but that issue has additionally been cured.
If you’ve been plagued by colors being displayed wrongly on the 10-bit display, then that has been resolved, and several PDF-related issues with Microsoft Edge are also now history.
For the full (and rather long) list of fixes applied, you can check Microsoft’s support document here.
So that as ever, there remain several known issues with the update, including Windows Sandbox falling over with an error whenever you attempt to fire it up following the OS language continues to be changed throughout the installing of the May 2019 Update. Microsoft says it’s busy working on a solution for this.
