Re: Latest NVidia Graphics drivers with 1.3.37 HD Audio driver: no NVidia HD Audio device gets insta

2019-01-28, 9:57 AM

Decided to see if I could duplicate your successful install of 416.78 from NVidia, acquired through GeForce Experience rather than through the regular search for latest driver which produced a download of 416.78 that won't install because it didn't include M3000M in the ListDevices.txt although that was precisely what the search criteria specified.

 

So I installed GeForce Experience, and was surprised to have it indicate that my currently installed 392.00 as the latest, most current driver applicable to my P70/1803 setup.  This is certainly a surprise, as regular "search" using the conventional method returns 412.16 as the most current STD+ODE WHQL driver. And of course the latest DCH+QNF driver is that 416.78 which won't install.

 

Looking a bit closer at the description of 416.78 it looks like it might be targeted for 1809 environments. Since I'm only at 1803 perhaps that might explain why GeForce Experience doesn't link to that even though I have checked that option to express my interest in "new features" and not just enterprise WHQL versions. But this still doesn't explain why 392.00 is pointed to, rather than 412.16.

 

Bottom line: I will contact NVidia support in the morning to have them help me out of this morass, and especially to explain why ListDevices.txt in the "search" downloaded 416.78 doesn't contain all of the GPU's it presumably should, specifically the M3000M which is what was searched on.

Re: Latest NVidia Graphics drivers with 1.3.37 HD Audio driver: no NVidia HD Audio device gets insta

2019-02-07, 11:49 AM

Latest update.

 

I installed GeForce Experience on my P70, which currently was set to discrete graphics (as has always been my normal operating mode).   For the past few weeks I've been running 392.00/1.3.37.5 (note the HDMI audio driver is leftover from an unsuccessful attempt using a recent NVidia driver, after which I rolled back just the graphics portion to 392.00) which as I've reported previously works "perfectly" with HDMI audio sent out to the LG TV.  I am also installed up to the very latest 2.28 BIOS and the very latest Intel ME 11.8.3561.60:

 

 

GeForce Experience advised me that a new driver was available (from the NVidia site of course just for the Quadro M3000M, having nothing to do with the Lenovo Optimus package).  It was 418.81/1.3.38.13, released 2/5/2019.  I decided to let it run, while still set to Discrete Graphics.  I have been running in Discrete Graphics on my W530 since 2013 and on my P70 since 2016 and have never had to revert to Hybrid Graphics in order to apply a retail driver from the NVidia site... which is the only driver I've ever installed, until this current issue when also experimenting with the Lenovo-provided Optimus package.

 

Anyway, I let the 418.81/1.3.38.13 Nviidia driver get installed by GeForce Experience.

 

 

The install went successfully and I re-booted. At this moment the LG TV is NOT connected to the P70.  I'm still connected to my Eizo monitor (which has no audio capability).

 

After the re-boot (and I did this twice, just to be sure everything on the desktop was "stabilized" before looking at Device Manager and Settings. Still connected to the Eizo monitor everything actually looks good, both in Device Manager as well as Nvidia Control Panel's digital audio.  Sound is coming from the laptop speakers but at least it looks like HDMI Audio device was properly installed into Device Manager.

 

 

 

I then shut down, disconnected the miniDP->DP cable from P70 to Eizo monitor, connected an HDMI cable from P70 to LG TV, and re-booted.  Again I re-booted twice, just to let the desktop "stabilize" in case that might make a difference.

 

Unfortunately, nothing is fixed.  Once again the previously visible HDMI Audio driver in Device Manager has now disappeared, just as it has been doing since I started this thread.

 

 

 

Although I haven't done it yet, my plan is once again to roll back just the graphics driver from the currently installed 418.81 to the previously installed version which will be 392.00 again.  I will leave the currently installed very latest NVidia HDMI Audio driver at 1.3.38.13, and expect it to still work perfectly with the 392.00 graphics component, delivering HDMI Audio to the LG TV.  I will report if this doesn't work, but based on my recent discoveries I now no longer blame the HDMI Audio driver 1.3.37.x and newer for the disappearing HDMI Audio symptom.  I blame some incompatibility with P70 BIOS for discrete graphics and something that's been changed and which is now present in any NVidia graphics driver newer than 392.00.... all of which exhibit the disappearing HDMI Audio symptom when connected to an HDTV.  Reverting the graphics driver back to 392.00 resurrects the HDMI Audio, all else remaining the same.

 

In other words, I am not able to duplicate your "success" resulting from upgrading Intel ME.  I am running the same upgraded Intel ME along with latest 2.28 BIOS and it doesn't make a difference. HDMI Audio is still failing.

 

But then I'm running 1803, and you're running 1809.  Perhaps that's the key to why you're seeing success now and I'm still not.

Re: Latest NVidia Graphics drivers with 1.3.37 HD Audio driver: no NVidia HD Audio device gets insta

I decided to manually install 1809 before backing out the graphics driver piece to 392.00.  I don't know why 1809 has still not been pushed out to ANY of the Win10 laptops and desktops I work with, but it hasn't.  So I initiated it manually just now.

 

Also, before proceeding, while it's still preparing I looked at Device Manager again (having disconnected the HDMI cable to the LG TV and gone back to my normal miniDP->DP cable from P70 to Eizo monitor).  And sure enough the HDMI Audio device has magically reappeared in Device Manager.  And sure enough Settings shows all of the HDMI audio items which were visible right after the 418.81 install, theoretically available for use if a cable gets plugged in.  So right now it looks just like it did post-install, and before connecting the LG TV.

 

I will see what happens after I'm upgraded to 1809, to see if that makes any difference with this latest NVidia driver installed along with the latest BIOS and Intel ME.

Nope. Sorry. No go.  Same results with 1809 installed. Disappearing HDMI Audio in Device Manager.  I cannot duplicate your "success".  Still fails for me.

 

Also, I cannot now roll back to the previously installed graphics driver. The "roll back" button is grayed out, probably because of the 1803->1809 upgrade and the establishment of a new "base".

 

So I'll just leave it this way, with 418.81/1.3.38.13 installed and forget about manually reinstalling 392.00/1.3.36.6 since I really have no true need to use the LG TV.  There is no problem running with my Eizo as the external monitor, and that's what I want, and it works fine.  Laptop speaker sound is also fine with me in this arrangement, and it too works normally.

 

Plus, with this latest NVidia driver installed it'll be easier to re-test if/when Lenovo releases a BIOS update in the not too distant future (hopefully) that actually fixes the now known and confirmed problem with Discrete Graphics and any NVidia graphics driver newer than 392.00 which triggers the "disappearing HDMI Audio in Device Manager" symptom.

 

Hibernation of this thread until Lenovo publishes a fix.

Did you ever think it could be the HDCP handshake between the P70 and your LG TV that is part of the issue? No problem with my Samsung TV at this point, but I don't run that way normally. Thanks for keeping up the pursuit.

Re: Latest NVidia Graphics drivers with 1.3.37 HD Audio driver: no NVidia HD Audio device gets insta

2019-02-08, 4:21 AM

Let's not forget that there was no issue with older NVidia graphics drivers 392.00 and before that, and still there is no issue, even when running with the vfery latest Lenovo BIOS and Intel ME versions which cause the symptom using newer graphics drivers.  So whatever turns out to be the explanation or bug here, it must be explained why 392.00 and older exhibits no such problem.

 

I am running around today updating the other Win10 laptops and desktops I support for friends and family, to apply 1809 manually (since none of them every received 1809 pushed out automatically by MS).  Very time consuming, of course.  The last remaining machine due for this upgrade is my own W530 laptop with K1000m graphics.  And I use that laptop in the proximity of a Samsung HDTV, which I will certainly use as I have previously to confirm that the problem still does or does not exist.  Remember the exact same problem (of "disappearing HDMI Audio in Device Manager" when operating with discrete graphics and newer NVidia drivers than 392.00) also occurs on the W530 (talking to a Samsung HDTV), not just on the P70 (talking to an LG OLED HDTV), although you said it doesn't occur on your P1.

 

So I will be sure and perform the same experiment again with my W530 and Samsung HDTV after upgrading Win10 to 1809 and upgrading the NVidia drivers via GeForce Experience, to see if anything has changed from prior also failing results.  I will also bring my P70 downstairs to connect to the Samsung TV as well, to see if it's actually the TV used and some HDCP interaction which might have a hand in explaining what's going on... but I don't think there will be any change.  I first noticed this issue in early November when I brought my P70 to Portland OR on a trip and tried using it to display on the hotel room HDTV to watch some recorded TV programs I'd brought with me. For sure this wasn't an LG or Sony or Samsung TV, but I can't remember what it was... although it was an inexpensive hotel-grade HDTV. And it failed here.  I re-booted my P70 to Win7 (which I also had available, and which had an older NVidia driver installed) and sure enough I could now get HDMI audio on the wall HDTV.  That was the beginning of this story.

 

I don't have any more expectation of success with my W530 than I did with my P70.  There might be something in common with how Lenovo implemented discrete graphics and HDMI on the P70 which is in common with the W530 but somehow different than what they did on the P1, which is relevant.  So until and unless Lenovo fixes this I'm just going to have to remain back at 392.00/1.3.36.6 since there is truly no reason to move forward any further. I am not a gamer, and 392.00 is 100% satisfactory for all my needs on both P70 and W530.

Re: Latest NVidia Graphics drivers with 1.3.37 HD Audio driver: no NVidia HD Audio device gets insta

Ok. W530 is now at 1809, which I installed first... and then installed GeForce Experience after, remaining at 392.00/1.3.36.6 until after the 1809 upgrade.  And then after being at 1809 I let GeForce Experience upgrade the NVidia driver to 418.81/1.3.38.13.  I figured if I did things in this sequence I would then still be able to roll back to 392.00 afterwards, which turned out to be impossible on my P70 where I'd already upgraded the driver from 392.00 to 418.81 before upgrading to 1809.

 

Here is what the GeForce Experience driver install did:

 

 

And, not surprisingly, the results of all of this on the W530 duplicated exactly my results on the P70.  Everything in Device Manager looked good right after the install, with Device Manager showing HDMI Audio Device as long as the Samsung TV was not connected.

 

 

 

  But as soon as I connected the Samsung TV (using miniDP->HDMI cable) the HDMi Audio Device disappeared from Device Manager.

 

 

 

However because of the sequence I upgraded through, I was indeed now still able to roll back to old "working HDMI audio" 392.00 (leaving the NVidia HDMI Audio driver at the newly upgraded 1.3.38.13).

 

And sure enough, after the rollback completed and I re-booted, I was exactly where I expected I would be. NVidia graphics driver was back at the "working" 392.00, HDMI Audio Device had reappeared in Device Manager and the driver was still the new 1.3.38.13.  And sure enough, HDMI audio was once again enabled on the Samsung TV.

 

 

 

 

So, the results on the W530 and discrete graphics, running with 1809 and 418.81/1.3.38.13 exactly mirrors the results on the P70.  HDMI Audio Device (which was present when the NVidia driver was installed but only the laptop screen involved) disappears from Device Manager once the TV is connected via HDMI cable.

 

And I was able to prove that with everything else remaining exactly as-is and untouched (including the newest 1.3.38.13 HDMI Audio driver) , all I had to do was roll back the NVidia graphics driver from 418.81 to 392.00 and magically everything now worked perfectly as far as HDMI Audio was concerned.  The HDMI Audio Device reappeared in Device Manager, thus allowing the TV's speakers (via HDMI) to be selected automatically as the default audio output device.

 

Q.E.D.

Was there a support ticker with Lenovo raised for this ? (Can't seem to find a reference in this topic and the other related topic).

Re: Latest NVidia Graphics drivers with 1.3.37 HD Audio driver: no NVidia HD Audio device gets insta

2019-04-22, 23:15 PM

No official ticket opened. Instead I communicated privately with someone on the inside in NC engineering, as I believed that would genuinely have a superior outcome. The symptom was, in fact, verified to occur on a P70 "in the lab", including all of the other variations and supporting clues and evidence. Actually that is how running in "hybrid graphics" as a "workaround" was discovered, except that running in "hybrid" mode is exactly NOT what  this thread is about. This thread is about losing HDMI audio when "discrete" graphics is in effect.  I'm not looking for a workaround. I'm looking for a "solution", that retains HDMI audio while still running "discrete" mode... same as has ALWAYS WORKED UP THROUGH GRAPHICS DRIVER 392.00!!!  It's only with any more recent graphics driver version newer than 392.00 that the HDMI audio incompatibility/loss symptom while operating in "discrete" mode occurs.

 

Anyway, after confirming the bug my "inside source" passed it on to the video team for further exploration and [hopefully] resolution presumably in some BIOS update pertaining to "discrete graphics" operation. Note again that I have confirmed this identical issue in my W530 running in "discrete" mode, so it's clear whatever is common in the W530 (K1000m) and P70 (M3000M) BIOS relating to "discrete graphics", it breaks HDMI audio on both machines. And it breaks it for both Win7 and Win10, so it's not particular to one Windows or the other. 

 

Finally, as my "driver backout" experiments confirm, this problem actually doesn't seem tied to the HDMI audio driver 1.3.37.x or newer, since I can retain HDMI audio with driver versions 1.3.38.x and newer... as long as I back out the graphics driver to 392.00 or older.  The HDMI audio issue conflictiing with W530/P70 BIOS in "discrete" mode is triggered by using a graphics driver newer than 392.00, not using an HDMI audio driver newer than 1.3.36.6. Any combination using graphics driver 392.00 or older WILL RETAIN HDMI AUDIO (no matter what HDMI audio driver is installed). Any combination using graphics driver newer than 392.00 WILL LOSE HDMI AUDIO (but all of those drivers come with HDMI audio driver 1.3.37.x or newer).

 

I've now just re-tested this as of right today, with the latest P70 BIOS 2.29 installed, as well as the latest nVidia retail driver package (installed through GeForce Experience): graphics driver - 425.31, HDMI audio driver - 1.3.38.13.  And just as before, nothing has changed and obviously there's been no Lenovo BIOS fix in 2.29 to address this issue. There is still a loss of available HDMI audio when plugging an HDMI cable into an HDTV. Only the analog Realtek HD audio laptop speakers are available to select for sound playback.

 

I will send another PM to my Lenovo NC contact, to see if anything is happening.

 

Again, latest report was that P1 systems don't have this problem, but then they have P-series graphics chips and clearly have different BIOS to support "discrete graphics" than that found on older P70 and W530 machines which have older M3000M and K1000m grapghics chips.
