Hi Sleepingmydayaway,
I'm Hendrix, here to help with your query on the Microsoft Q&A forums. Apologies for any inconvenience you are experiencing. I know how maddening crackling, popping, or delayed audio can be, especially when it suddenly gets worse after an update.
To my knowledge, Microsoft has already shipped fixes for specific scenarios and continues to roll out improvements via cumulative/optional updates. Installing the right updates and removing a few conflicts typically restores clean audio.
Below is the guide that has consistently helped Windows 11 users fix exactly this problem, please kindly follow:
1 - Install available Windows updates (including Optional)
- Go to Settings → Windows Update → Check for updates.
- If you see an Optional update related to audio/Bluetooth/USB, install it too (these often carry targeted audio fixes).
Microsoft has shipped stability fixes for audio stutter/NDI/driver interactions in recent builds.
2 - Disable unused HDMI/Display audio devices
- Right‑click Start → Device Manager → Sound, video and game controllers.
- Right‑click → Disable device for NVIDIA High-Definition Audio, AMD/Intel Display Audio, or monitor/HDMI audio outputs you’re not using.
- Test audio again.
Even when Realtek/USB is set as default, display audio drivers can still interfere and cause pops before notifications or when sound “starts”.
3 - Switch to Microsoft’s generic audio driver (fast rollback)
- In Device Manager, right‑click your primary output (e.g., Realtek(R) Audio).
- Update driver → Browse my computer → Let me pick.
- Choose High-Definition Audio Device (Microsoft) → Next → Yes.
- Test audio.
Some Realtek/UAD builds after 24H2 don’t play nicely on specific models. The in‑box Microsoft driver is a clean baseline that often eliminates crackling.
I look forward to receiving your update and I'm willing to collaborate with you till we resolve the issue. Please keep me informed. If the answer is helpful, please click "Accept Answer" and kindly upvote it. Accepting an answer helps us track the effectiveness of our support efforts.
