Re: X1 Carbon 7th Gen sound card can't start

My turn to be sorry about the late answer, I didn't see yours.

 

The model number is 20QDCTO1WW.

 

Today I ctually found out that the microphone is still not working FYI, though I found a way to have the speakers work. So there is a bad effect and it makes it hard for online meetings. Just for your information.

 

I'm very aware that a bug needs to be reproduced before a solution can be found...

 

I didn't find the logs that were asked for earlier in this thread, please let me know if I need to do something specific for them to be created or whether I need to do something to find them. I assume logs can help see where the problem lies.

 

Also, I'm willing to try re-installing drivers one more time. Could you point me to the right driver and the procedure to make sure old ones are out and the new one is used?

 

Thanks a lot for your help! Warm regards.

Please uninstall all Realtek audio driver and install the 6.0.8699.1 realtek audio driver on Lenovo support page.

Besides,do not paste anything on the top of the panel, it has some output hole(about 4 small holes).

Re: X1 Carbon 7th Gen sound card can't start

The 4 holes, do you mean the ones at the top of the display, which are the microphone holes? I don't cover them no, if so. The mic input is not found in Windows as seen in the picture. I understand the suggestion, it happens that people do things like that. In my time in tech support around audio software, some people didn't plug the speakers in the output of they new sound card and thought it didn't work. It may happen to me to do such things as well!

As for the driver, it's downloading and I'll report back. The is one Realteck device in the  Device manager, for which I'll uninstall the driver and install the one you pointed to:

As a reminder, it's the Intel driver that shows a yellow mark, here:

Re: X1 Carbon 7th Gen sound card can't start

So, I uninstalled the Realtek device and reinstalled it with the driver provided. This didn't improve the situation. Audio output still worked, input wasn't starting, and the Intel SST (OED) still had a yellow mark.

 

So I proceeded and tried to install the Intel SST driver that is contained in the package I downloaded for the Relatek driver. It installed but now the audio doesn't work at all, again.

 

The Intel SST Audio Controller driver version is 10.23.0.2618

The Intel SST (OED) driver version is 10.23.2618.3

About your bug, it seems that smart audio driver not installed successfully, so the sound input device is not recognized successfully.On my machine, you can see that input show the intel smart audio device.

Could you please show whether you really installed the audio driver successfully? Please capture picture like below.

Re: X1 Carbon 7th Gen sound card can't start

Hi,

 

Thanks a lot for staying with me! Here are the drivers installed:

latest 1.png

With these, Audio doesn't work at all, neither speakers nor microphone are available.

 

If I install an older driver (as seen here) the speakers work, I can plug a headphones, but the microphone still can't start...

Note that in both case the Intel SST drivers show in "System devices" and not in "Sound, Video and Game Controllers" (I have difficulties uploading screenshots for some reason, let me know if you need one)

Re: X1 Carbon 7th Gen sound card can't start

Seems identical to yours:

Now I see that this device appears for you as well in System devices. What I DON'T see on my system is an entry for Intel SST technology in the Sound, video and game controllers.

Re: X1 Carbon 7th Gen sound card can't start

I really wonder if something's wrong with the hardware somehow..

 

As a reminder, after a visit at the Lenovo service center here in Berlin, where the person tried to boot the machine with a Linux system and we could see the audio was working,

 

On the person's advice, I then re-installed Windows 10 clean, without keeping any file, which I downloaded from the Microsoft website. Audio didn't work still - surprising after a fresh install.

 

I did the Windows updates, downloaded Vantage and did the updates available, still no audio...
