How is Linux compatibility with the new X1C7 and X1Y4?

Is sleep working fine on these laptops? I don't care about the fingerprint sensor under Linux but I do care about basic functions such as brightness/volume control keys, wifi, BT, etc.

Using pop_os! 19.04 on X1C7

Sleep seems to be working fine.

Bluetooth works fine.

Brightness works fine.

Microphone isnt getting detected.

Volume is either 0% or 100%. Scaling seems broken.

 

Not having the microphone and the iffy volume is killing me

The micro phone works if you update the /etc/pulse/defaulf.pa file look for the commented line with load-module module-alsa-source device=hw:1,0. Adjust the hw:1,0 to match the device from the arecord -l command as for the device number,  mine was hw:0,0
As for the sound if you use amixer command and adjust the granularity of the volume level you can adjust the output. I do see that if using 4 speak output the rear speakers are louder so I had to adjust the master for the rear speakers down a little

After running arecord -l, i get the following:

**** List of CAPTURE Hardware Devices ****
card 0: PCH [HDA Intel PCH], device 0: ALC285 Analog [ALC285 Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

 I then went into /etc/pulse/defaulf.pa and changed

#load-module module-alsa-source device=hw:1,0

into

load-module module-alsa-source device=hw:0,0

 

I then ran this command in terminal to restart pulseadio pulseaudio -k ; pulseaudio -D

and then input no longer says Microphone (unplugged) and now says Built-in Audio. However the microphone still doesnt work. Any other ideas?

S0 and S3 sleep are working correctly as far as I can tell all tests worked as expected.  As for the internal microphone I am looking into that issue as I was also unable to get sound into the system. The headset jack is working correctly for both sound and microphone.

Hello, 

I have solved the problem with the not working soudkey's, but still have the problem that only the two lower downwards speaker are working. The rear upper speakers don't work. Maybe someone has a solution for that problem. Thanks!

Not sure if you're referring to the same issue I was having the issue where the audio wasnt scaling correctly.

 

If it is I fixed it by doing what was in this forum post.
