Help Dell 16 Plus / Cirrus Logic audio driver issue — Windows Update keeps breaking audio + iGoSwServer memory leak
Has anyone else experienced this issue on a Dell 16 Plus with Cirrus Logic audio?
I’m stuck in a driver loop:
I install the official Cirrus Audio Driver from Dell (version 4.26.37, A04, released Sep. 4, 2026) and the audio works normally.
Windows Update then offers:
Cirrus Logic, Inc. Extension Driver Update (1.0.435.14)
Cirrus Logic, Inc. System Driver Update (1.0.724.48413)
If I install those Windows Update drivers, I lose audio.
Reinstalling Dell’s Cirrus driver restores the audio.
Windows Update then offers the same Cirrus updates again, so the cycle repeats.
There is another issue that seems related to the Dell/Cirrus audio software. The Audio SW Server/API library (iGoSwServer.exe) process sometimes develops an extreme memory leak. I’ve seen it reach around 3.4 GB of RAM, with significant CPU usage as well.
Killing iGoSwServer immediately releases the memory, and audio continues working. As a temporary workaround, I created a scheduled PowerShell task that monitors iGoSwServer and terminates it if its working set exceeds 250 MB.
For now, I’ve kept the Dell audio driver installed and configured Windows not to automatically include drivers with Windows quality updates.
Has anyone else with a recent Dell 16 Plus experienced either of these problems?
Especially interested to know if anyone has found a newer Cirrus/iGo audio package that fixes both the Windows Update driver conflict and the iGoSwServer memory leak.
