Windows Audio Device Graph Isolation [SOLUTION]

This conversation is in relation to the memory leak I have been experiencing on my Strix G16 laptop. For over 2 weeks I have been going crazy, trying EVERY solution mentioned out there:

Some of the solutions I have already tried were:

• Disabling all audio enhancements (e.g. Razer 7.1 Surround Sound)
• Disabling all sound effects/ e.g. Spatial Sound etc.
• Uninstalling/ Installing Windows drivers
• ALL the updates you can imagine….
• Cancelling the Windows Audio Device Graph Isolation process directly from the task manager.

… and couple of others I cant remember. I have been watching countless videos on YouTube and relentlessly reading all the Forums for an answer.

My problem has never been the spike in CPU usage, but simply a memory leak. The Windows Audio Device Graph Isolation would start at 1GB and slowly (but surely) creep up to 8 - 9GB. I call it memory leak, because during at an idle moment in games, I would minimise the game - open task manager (whilst nothing else is open) and simply watch Windows Audio Device Graph Isolation slowly eat more into the memory.

There is 32GB (5600 MHz) installed on my laptop, but even then I have seen moments where 27 - 28GB would be in use, it even reached 31GB once and froze the laptop completely.

So, this is the background to my problem now onto the solution:

Today, I was done with Razer (I am using a Razer Headset and it came with this 7.1 Surround Sound ench.) and I was about to completely uninstall EVERY audio driver on my laptop and start fresh. This is what happened:

1. I went to “Installed apps” on Windows 11.
2. Clicked “Uninstall” on “7.1 Surround Sound”
3. It prompted a Razer UI with the option “Uninstall” and “Repair”.

I thought “what the hell” I might just give it one more go. (Bare in mind I check for Razer “updates” all the time)

1. CLICK on “REPAIR”
2. Once you click on REPAIR it takes a minute or two to process a few things.
3. Let it process, don't click on anything else.
4. Once its finished, your memory leak problem should be solved.

I swear whatever Razor did, I dont understand why they couldnt simply fix it with an update or simply disseminate the information that there is a fix.

Once everything is done, you can enable all the enhancements. My memory hasn’t spiked since. I do let the Spatial Sound on OFF. (< FYI)

But this process solved my problem.
