try rolling back the Intel SST drivers instead

Still the same log, next I will try a clean install of Windows 11 on another partition to test the current drivers (first I will slipstream the INF files offline into the ISO).

Recently this log started appearing in my event viewer, it appears each time a sound plays on my HP laptop. I'm asking if anybody have a clue what's going on.

Attention : Spoiler !

Code:

Log Name: System Source: Intel-SST-OED Date: 15/03/2026 12:05:30 AM Event ID: 19 Task Category: This task logs error codes to system event log. Level: Information Keywords: User: LOCAL SERVICE Computer: HOUSSEM-HP-PB Description: Check the remaining resource budget. Module exceeds resource budget, failed to AllocateFwCps, STATUS = Insufficient system resources exist to complete the API.. Event Xml: <Event xmlns="http://schemas.microsoft.com/win/2004/08/events/event"> <System> <Provider Name="Intel-SST-OED" Guid="{6f789161-d86f-4063-9e66-41f26b5da238}" /> <EventID>19</EventID> <Version>0</Version> <Level>4</Level> <Task>6</Task> <Opcode>20</Opcode> <Keywords>0x8000000000000000</Keywords> <TimeCreated SystemTime="2026-03-14T23:05:30.7283925Z" /> <EventRecordID>237741</EventRecordID> <Correlation /> <Execution ProcessID="3352" ThreadID="2496" /> <Channel>System</Channel> <Computer>HOUSSEM-HP-PB</Computer> <Security UserID="S-1-5-19" /> </System> <EventData> <Data Name="message">Module exceeds resource budget, failed to AllocateFwCps</Data> <Data Name="status">3221225626</Data> </EventData> </Event>

Realtek Audio driver : HDXSSTHPBNB.inf , DriverVer=02/03/2026, 6.0.9951.1
IntelSST OED driver : IntcOED.inf, DriverVer = 10/17/2022,10.25.00.8130
I suspect the log started appearing after a recent update of the Realtek Audio driver, because the ISST OED driver hasn't been updated since October 2022.

I finally managed to find the root cause of the event log :
SHORT ANSWER
it's a Realtek extension to the main Intel Smart Sound Technology (SST) driver.
After uninstalling the INF and rebooting, the log stopped popping in the event viewer. I tried reinstalling it and the log immediately started reappearing.
With further investigation, and the help of AI, I was able to understand exactly what was causing the log :
LONG ANSWER

Attention : Spoiler !

I finally managed to track down the exact root cause of the Event ID 19 spam (Source: Intel-SST-OED, Description: "Module exceeds resource budget, failed to AllocateFwCps") that was flooding my Windows 11 Event Viewer every single time a sound played on my HP laptop.

I initially thought this was caused by a recent update to my main Realtek Audio Driver. However, after digging directly into the Windows Driver Store, I realized the main audio driver is actually innocent. The true culprit is a silent, modular OEM Extension driver that Windows Update (or HP) installed in the background alongside it.

Here is exactly what is happening under the hood and how to fix it:

The Root Cause: The Realtek Extension INF
The issue stems from a specific Extension driver named IntcOED_OemLibPathExt.inf (in my case, Provider: Realtek, Version: 10.25.253.002, Date: 01/08/2024).

The Architecture: Inside this extension's package, there is a subfolder named Libs containing a compiled module called sraudio_lib.bin. The INF file writes a registry key (OemLibPathExt) that explicitly tells the base Intel Smart Sound Technology (SST) DSP firmware (dsp_fw_release.bin) to load this custom Realtek module into its memory.
The Crash: Every time an audio stream initializes, the Intel DSP wakes up and attempts to allocate firmware resources to load this Realtek extension via the AllocateFwCps (Firmware Coprocessor) API call.
The Resource Budget: The specific version of sraudio_lib.bin bundled in that extension package is either too large or poorly optimized. It exceeds the hardcoded memory/processing budget allowed by the Intel DSP firmware. The Intel chip denies the load request, drops the module, and logs the Event ID 19 error: "Module exceeds resource budget."

Solution 1: Remove the Problematic Extension (The Quick Workaround)
To stop the event spam immediately, you can sever the link between the Intel DSP and this oversized Realtek module.

Locate and completely uninstall the IntcOED_OemLibPathExt.inf package from your system. You can do this using Device Manager (under "Software components" or "System devices") or by using a tool like Driver Store Explorer / pnputil to delete it directly from the Driver Store.
Once uninstalled and rebooted, the registry pointer is gone. The Intel firmware will no longer attempt to load the problematic sraudio_lib.bin module, the AllocateFwCps API is never pushed past its limit, and the Event Viewer spam stops completely. Your audio will continue to work flawlessly using the standard base drivers.

Solution 2: Update the Extension (The Official Fix)
If you prefer to keep the OEM audio enhancements (like specific EQ profiles or noise cancellation) that this extension provides, the core fix is to install a newer version of the extension package.

Look up or wait for a newer release of the IntcOED_OemLibPathExt.inf driver via Windows Update, the Microsoft Update Catalog, or HP's official support page.
A newer version will contain an updated, properly optimized sraudio_lib.bin file that corrects the memory allocation bug, allowing it to load safely within the Intel DSP's resource budget without triggering the error.

I hope this saves someone else the headache of troubleshooting this log!
