Stop to delete amdacpksl with AMD drivers #51

Closed mirh closed 4 years ago

mirh commented 4 years ago

It comes with realtek driver, and of course they break when you wipe the gpu one.

Can you point me the Realtek driver package that have this file? I only see this with AMD Catalyst driver.

I was able to spot some situation where it seems to come with some realtek distribution too. I'll try to see if I can identify the Realtek vs the AMD one.

If you have a system with the problem you described, can you please do a search from this key (Without A DDU run and with everything installed / working) : HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum and search for a LowerFilters named amdacpksl once/if you find it, tell me the reg path of where you found it. I suspect it to be under a similar location: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\HDAUDIO\FUNC_01&VEN_10EC&DEV_1168&SUBSYS_10438723&REV_1001\4&1c71647&0&0001

I'm getting killed if I try any little more to "understand rather than straight fix".

Said this.. It seems you might be right about that file ever shipping inside the graphics drivers. But that was the I2S driver, not the HDMI one. Which imo hasn't really much to do with graphics, and indeed newer driver packages don't have it. It's just shipped by realtek and/or OEMs.

For the moment, I'll follow your advise and prevent its removal as it seem to be used at many places. I'll try to make it more intelligent in the future and remove it only when not used. But for the moment, I'll prevent completely.

Uhm? I never argued for amdacpksd. That's still shipped in modern display drivers (for as much as only in the W8+ editions).

I preferred to remove it too while I was at it until further investigation.

They have nothing to do with each other? Yes, they both have "ACP" in the name, but one refers to the audio coprocessor meaning trueaudio (and that's why it ships with gpu drivers). I reckon it's just a firmware loader for the DSP. The other is the embedded audio coprocessor found in APUs.

It seem you are right, I will re-add amdacpksd in the removal process.
