Modify the HD Audio driver's timeout values

[Computermaster]

Hey I'd like to make a feature request. Quoting my most recent benchmark thread:

If you have a VR headset and are having issues with the non-USB audio being unavailable, run this script: https://pastebin.com/q290MdtQ

If you have other weird issues and are having audio output by your video card, I would also recommend giving that script a shot.

Here is more background on this issue

The TL;DR is that nvidia in all their ungodly wisdom have the HD Audio driver set to go to the deepest sleep state possible after ***four seconds***, and many devices are incapable of waking it back up. My script changes it to never go to sleep after it's installed, but I think it would be a helpful addition to have NVCleanInstall fix it too.

The file to change is (default location)

C:\NVIDIA\DisplayDriver\436.48\Win10_64\International\HDAudio\hda.inf

The section that needs to be altered is

[NVHDA_D3cold.AddReg]

The default values are

HKR,PowerSettings,ConservationIdleTime,1,04,00,00,0 ; 4 seconds for idle power management when on battery - enabled
HKR,PowerSettings,PerformanceIdleTime,1,04,00,00,00 ; 4 seconds for idle power management when on AC power - enabled
HKR,PowerSettings,IdlePowerState,1,03,00,00,00 ; go to D3 for idle power management

Proper values would be

HKR,PowerSettings,ConservationIdleTime,1,00,00,00,0 ; 4 seconds for idle power management when on battery - enabled
HKR,PowerSettings,PerformanceIdleTime,1,00,00,00,00 ; 4 seconds for idle power management when on AC power - enabled
HKR,PowerSettings,IdlePowerState,1,03,00,00,00 ; go to D3 for idle power management

I honestly can't see putting the driver to sleep saving any significant amount of power.

NVCleanstall 1.1.0 has just been released, which adds this feature

Is this a fix for delayed audio (that would, for example, keep short Windows sounds from happening at all) that needs fixes like AVR Audioguard (no longer available) or SPDIF KeepAlive (which stopped working for me for unknown reasons)? I went back to analog audio at some point because of that.

P.S. Is this possible to do with Realtek and AMD's HDMI audio?

I'm wondering this same thing. Did you ever find a conclusive answer to this?

I tried it and it did no good.
