I've installed ubuntu on my new Dell G3 and I can't make sound work. Usually after installation/update I tackle these things but this time I'm kinda stuck.
Initially after installation I saw only "dummy output" in my output devices and nothing in input devices.
I've already looked into these:
Here
And here
And here
I've tried to reinstall pulseaudio and reload alsa:
sudo apt-get install --reinstall alsa-base pulseaudio
sudo alsa force-reload
After it did not help I also tried
alsactl restore
which gave me the following output:
alsactl: state_lock:125: file /var/lib/alsa/asound.state lock error: File exists
alsactl: load_state:1683: Cannot open /var/lib/alsa/asound.state for reading: File exists
Found hardware: "HDA-Intel" "Nvidia Generic" "HDA:10de0099,10280949,00100100" "0x1028" "0x0949"
Hardware is initialized using a generic method
This is output of "inxi -SMA":

and output of "lspci | grep Audio":

pavucontrol did not help to understand anything either. After all manipulations I've got "HDMI / DisplayPort - TU116 High Definition Audio COntroller" as the only option in Output device and nothing appeared in Input Devices. Headset does not add any device.
Help me, please. What do I miss?
