I am posting this as I've gone through several posts here and couldn't understand exactly the issues I'm having and the solution. I recently bought a Dell Vostro 15 5590 (see here for all specs). Relevant hardware information:
- 10th Generation Intel Core i7-10510U
- Wireless adapter Intel 9462 NGW
- Audio controller Realtek ALC3204
It came with Windows 10, but then I decided to install Ubuntu 18.04.3 LTS alongside it. When I first booted into Ubuntu, I noticed the wireless wasn't working. The card wasn't even showing up in the UI, but with
lspci I could see it. After a thorough search I found this which worked. I basically installed the
linux-oem-osp1 package and after a reboot I was able to connect to a Wi-Fi network.
However, I then noticed that the audio wasn't working, neither input nor output. In the UI it was only showing the dummy output but again through
lspci I could find my sound card. Found some questions here but nothing worked. Does anyone have any clue about this?
UPDATE: About the sound issues, I tried all the alternatives provided in this link. For the step where I should run the alsamixer utility, it failed with the message
cannot open mixer: No such file or directory. I believe that is because it cannot find any sound card?
UPDATE WITH PARTIAL SOLUTION: By following the steps suggested by Pedro below, I was able to have sound output and wi-fi working. It basically consists on going back to the kernel 5.0.0-37-generic, which makes the sound work, and then installing the package
backport-iwlwifi-dkms with the commands:
$ sudo add-apt-repository ppa:canonical-hwe-team/backport-iwlwifi $ sudo apt-get update $ sudo apt-get install backport-iwlwifi-dkms $ reboot
The internal microphone still doesn't work, although the microphone of a headset works fine. I will go after this issue now and will update this with more info if I get it to work.
