Big problems with M4A after updating to Windows 11 22H2

Hi Pete, thank you for following the issue closely. This is much appreciated.

https://aka.ms/AApf7g9 this is a link to my feedback hub post from 6 months ago, maybe it was not descriptive enough and I apologize.

I am using rekordbox with all the latest updates available and I confirm that some tracks are now fine (whereas in the past they had issues), but others are screwed in the sense that they slow down randomly or block.

All bought on iTunes and m4a format to provide some context.

This screenshot provides a good visual example of the stuttering that we are experiencing.

Thank you again for your support, I think we all value it!

Update:

The team has figured out what happened. It really was working in the test builds, and in the Insider builds. However, there was a configuration mistake when this was moved to the retail release. That resulted in the corruption effect because it wasn't a complete release. The code works, and is still in the Canary Insider builds.

The team is doing two things:

1. Disabling the current codec fix in the releases that are going out so more folks don't run into this, and we don't make it any worse. I'm not sure when this updates on the download servers but it will be at least a few days.
2. Getting the configuration into, we hope, the end of month's fixes. Yes, this will mean at least one more month of waiting. The fix date is not yet confirmed because this is fresh from the team today. Once I know an actual planned date, which is not guaranteed to be this month, I'll update here. The feature team gets the urgency of the situation, as do I, and this is a shorter period than it usually takes to roll out a non-security update.

Please also note that "Patch Tuesday" is a public interpretation of what we do, but they aren't always on Tuesdays -- we go by weeks of the month, and the day that rolls out for you also depends on your configuration, update settings, geo location, and more. We never refer to patch Tuesdays internally, so end of month really does mean up to the last day of the month. Your continued patience is appreciated.

We have all the data we need on this, and no longer need any more feedback hub entries or reports. Thank you to all who have provided them.

If you've already downloaded and installed the current update, I recommend uninstalling it while you are within the time window to do so.

Once again, sorry for the impact and bad experience here.

Pete

Hi all

I don't have time to submit to the Feedback Hub until Sunday, but I just wanted to add my voice to the chorus saying it is indeed worse now. The same iTunes M4A files that were jumping up and down in volume now sound totally corrupted in both Traktor and Windows Media Player.

Mixxx, to its credit, won't even load the files.

I have the same problem after installing latest Windows KB5034848 update. I reinstalled audio drivers, but it didn't help the playback issue. The music sounds as it is currupted. I'm unable to listem to a m4a format music. Should I unistall the update oraz wait for Microsoft solution?
