Is there a known audio issue with a recent Win 7 update?

Is there a known audio issue with a recent Win 7 update?

I watch TV and movies on my Win 7 PC, 23" widescreen monitor, with the audio sent to a stand-alone 'stereo'(5.1 receiver).

Recently, a few weeks ago, after a MS Win 7 update, my audio started sounding garbled, poppy, clicky, thumpy, and the longer times between reboots, screechy. After a reboot, the audio is fine for about a day or so, then goes 'bad'.

Is anyone aware of a recent Win 7 update that would cause this? And if so, has MS put out a 'patch' for it?

If not, should I 'back out' that update?

I've checked the following:

1) receiver is OK, as stand-alone CD/DVD players play audio/video fine.

2) The cables between my PC and receiver are plugged in tight, not broken, or bent.

3) Ran the mdsched.exe(Windows Memory Diagnostic), came back OK.

I'm current with all MS updates, there is one Nvidia Graphics Adapter update that I would prefer not doing, as a few years back, I updated my GPU and it totally messed up my WMP. Does the Nvidia card just process video, or does it also process audio? If it does process audio, maybe that's the issue?

Anyone have any 'tests' that I can do to locate the issue that's causing sound to go bad about a day after rebooting?

Win 7, 16GB RAM, with all current MS updates.

Thanks!

Hi

Apparently so, the final update which caused the Desktop background problem was "repaired" with another "final" update, which is causing this and other problems.

Cant remember where i saw it today.

Way to go MS, so thier liable, maybe, to issue another one

So, maybe wait for MS to issue another 'final' update patch?

Hi

If you un-install the Final and and repair, (preview optional) updates you should be back on course.

As for another i wouldn't hold my breath

Just checked 'Windows Update'...there's 2 'important'...Security Intelligence Update KB2310138, and Windows Malicious Software Removal Tool KB890830, and 2 'optional'...2020-01 Preview of Monthly Quality Rollup KB4539601 and nVidia Graphics Adapter...none of those seem like they would fix the audio...but I'm no expert, so maybe?

Is the 'Update for Microsoft Windows (KB4532945)' installed on 2/9/20 the 'final' update? Is that the one I should back out?

Is it a known issue that the most current Win 7 update 'Update for Microsoft Windows (KB4532945)' installed on 2/9/20, affects the 'network adapter'(Realtek PCIe GBE Family Controller)?

don't know if this will help fix your audio problem but regarding the Realtek PCIe GBE Family Controller device, the latest version of that driver for Win7 is v7.129.1118.2019 dated 11/18/2019. Get the latest Realtek PCIe GBE LAN driver from Station drivers (that driver is also available on Realtek's web site but you have to type in a valid email address just to actually download the drivers on the Realtek site)

Thanks!

those specs are incomplete. need name of motherboard or computer, CPU, audio device, etc.

use either HWINFO or Speccy to gather complete specs, maybe even name of the audio device(s)




Edit2 - another thing:


use tools like DPC Latency checker or LatencyMon to diagnose audio popping/crackling problems

Thanks for those links, I'll check them out.
